7 Classroom Supplies Every Elementary Teacher Needs

August 3, 2019 by Krejci Creations

Raise your hand if you are ready to go back to school!?!? Well, ready or not, here it comes…and the more organized and prepared you can be from the start, the better. 

Making your list of classroom supplies, however, can feel like registering for a wedding. You want all the things! How do you narrow it down? 

You’ll still need certain necessities like post-it notes and pencils, but here are 7 nontraditional classroom supplies you might want to consider adding to your list.

*The links provided are Amazon affiliate links. There is no extra cost to you, but purchasing through these links helps support my small business. 😉

Classroom Supplies #1: Magic eraser Sponges

I will NEVER go back to using traditional erasers after using magic eraser sponges. They are exactly as advertised…MAGIC! They make erasing on laminated materials, such as task cards, so much easier and are used every single day in my classroom.

To assure I never run out of these little gifts from heaven, I always put them on my wish list. I even cut them in half to make them last longer. This pack of 50 from Amazon might even last you the entire year!

Classroom Supplies #2: Clear Sheet Protectors

I seriously could not live without sheet protectors. I use them ALL THE TIME. They are a great alternative to laminating and are perfect for holding math work mats, student choice boards, and math games. 

You can even place a sheet of white card stock inside and they instantly become a dry-erase board! I literally have hundreds of sheet protectors and use them in so many different ways. In my opinion, they take less time to prep and work better than laminating. 

The Amazon sheet protectors and Office Depot sheet protectors are my favorite! The most common way I use sheet protectors is for work mats, which means I can reuse them year after year. Talk about a time-saver! I store work mats in binders and organize them by chapter.

Classroom Supplies #3: Ultra Fine Dry Erase Markers

During a whole group lesson, my students use traditional (chisel tip) dry-erase markers on their whiteboards. These are my preferred markers because the larger size allows me to see their work from a distance. 

Unfortunately, traditional markers are too thick for task cards. So instead, I’ll have my students use markers with ultra-fine tips. Because they are so thin, it’s much easier for them to show their work on the task card.

I store these at my small group table and remind students they can only use them when they are with me. It’s a great way to distinguish their materials from mine. Plus, they are super easy to erase from laminated materials. 

If you have a hard time finding ultra-fine tips, check out Office Depot or Amazon. 

Classroom Supplies #4: Student Eraser Pads

I’ve tried many different methods when it comes to student erasers: old socks, small hand towels, and magnetic erasers to name a few. Nothing has worked better than these facial pads!

Facial Pads for Student Erasers

I grabbed this idea from another teacher’s blog years ago. They last forever and can even be washed. In fact, I’m reusing mine this year after a good run through the washing machine. Just look at all the fun colors!

You can find these at Dollar Tree and Amazon, which I’ve linked for you.

Classroom supplies #5: 9 x 12 Manilla Envelopes

9 x 12 Manilla Envelopes

You are not alone if you struggle to organize and store math centers. I used to struggle with this until I began using manila envelopes. They take up little room and can be labeled with product covers and answer keys. 

I recommend laminating the envelopes to keep them in good shape for future use. I also organize them by chapter, making resources easy to find when I’m in a hurry!

Classroom Supplies #7: White out Tape

If you’re like me, you love using flair pens and skinny markers to grade papers. If you’re also like me, you make mistakes often. 

Instead of scratching out my writing and making a mess, white-out tape allows me to neatly write over my mistakes. It’s much cleaner and easier than liquid white-out. I will never go back! 

In addition, white-out tape is a great way to make accommodations to a test. For example, I often use it to eliminate an answer choice or a Part B to a question. 

You can find white-out tape just about anywhere, including Amazon!

Classroom Supplies #7: Cardstock

If you plan on using an activity more than a few times, cardstock is a must. It can withstand the use and abuse of elementary students, especially when laminated. 

Cardstock works well for task cards, games, math work mats, bulletin board letters, and name tags. My preferred brand is Neenah Bright Cardstock and of course, Astrobrights! I love using bright colors with my math centers. 

Take a look at the video below to see how these colors really spruced up this Factors and Multiples Sort!

Whether you put these classroom supplies on your shopping list or on your wish list, I hope you find as much success with them as I have. I wish you a happy and healthy school year ahead!

Until next time,
Happy Teaching!

How to Make the Most of Review Days with Boom Cards

May 12, 2019 by Krejci Creations

I used to DREAD review days. The challenge of trying to keep an entire class engaged and on task left me overwhelmed and exhausted. While most of my 4th graders didn’t need to review, others required serious remediation. I tried playing review games (who doesn’t love a good game of Jeopardy?), but only a handful of students were engaged and very few benefited. In the end, I never felt satisfied and knew there had to be a better way of utilizing these days.

Small Group Review

One day it dawned on me. What I needed to do was shift my focus from whole group review to small group review. This way, I could meet with the students who truly needed remediation separately from those who did not. But how could I know with certainty which students to reteach and what skills to focus on? I needed data, and I needed it fast. Boom Cards™ immediately came to mind.

Going Digital

If you haven’t tried a set of Boom Cards, pencil them into your next unit lesson plan. These digital task cards are such a time-saver and are easy to implement in class. They provide immediate feedback for students and will give you valuable data, including which problems students answer incorrectly and how long it takes them to complete the assignment. Below is a picture of the data analysis Boom Learning does for you.

Boom Learning data

On top of that, students LOVE them! They were a game-changer for me. Learn how to use Boom Cards in the classroom in my previous post!

Chapter Review Boom Cards

I created my first set of Chapter Review Boom Cards during Chapter 7 of Go Math: Add and Subtract Fractions. My students completed this review two days before the test. The data showed me exactly who was struggling and what concepts they were struggling with.

It was obvious they didn’t need more practice adding and subtracting fractions. Their struggle was with mixed numbers. Furthermore, the data showed me who did not require additional support from me. I was AH-MAZED! Planning for review days just got that much easier. I now knew exactly who to work with and what to work on.

I first met with students who needed remediation, and we only worked on mixed numbers. In addition, I provided enrichment activities for the others, including the next chapter’s pretest. How did I not think of this sooner? Immediately, I got to work on creating a set of Chapter 8 Review Boom Cards. Before I knew it, all 13 Chapter Reviews were finished!

Less is More

From here on out, I use the phrase “less is more” to plan out review days. I meet with fewer students and cover fewer topics but accomplish more. I could not achieve this without the data from my Chapter Review Boom Cards! Below is a preview of my review on Angles and Degrees, which aligns with Chapter 11 in Go Math.

https://krejcicreations.com/wp-content/uploads/2019/05/video-preview.mp4

 

All 13 Chapter Reviews contain 3-5 questions per lesson and use a variety of question types, such as drag-and-drop, multiple choice, multiple select, and fill-in-the-blank. Questions are organized from the first lesson to the last, making it easy to read and interpret data.

If you are short on time, assign them for homework! The immediate feedback will help you plan which skills to review in whole group and which to review in small groups. In addition, you can identify which lessons you need to focus on more throughout the unit.

Digital and Printable Versions

If you have limited access to technology, I also offer printable versions. Personally, I like to use both. For example, when looking through my data I’ll pull out task cards aligning with the questions most commonly missed. I can then use these cards to review with students and discuss why they missed the questions in the first place and/or what misconceptions they had. Why reinvent the wheel when it’s already been made?

If you struggle with review days, try my “less is more” approach. Use data from Boom Cards to prioritize and plan your small group activities. Click on the links below for more information regarding my 4th Grade Math Reviews!

Until next time,

Happy Teaching!

Winter-Themed Fraction Fun for Elementary Students

February 23, 2019 by Krejci Creations

If you teach fractions, chances are you teach them during the long, dreary, and cold winter months. While I’m not a huge fan of winter, I am a fan of using winter-themed fraction activities for my small group center. They bring me joy and provide instant engagement and excitement to the classroom!

Improper Fraction Snow Globe Sort

One of my favorite winter-themed fraction resources is this Improper Fraction Snow Globe Sort. It is hands-on, versatile, engaging, rigorous, and purposeful. I love seeing the look on my student’s faces when they realize they’ll be working with snowflakes and snow globes. They are always curious and anxious to discover what it’s all about! To prepare, simply spread out the improper fraction snowflakes and arrange the mixed number snow globes in order from least to greatest.  

improper fraction sort

The goal is for students to correctly sort the improper fraction snowflakes into the appropriate snow globes. To do this, they first convert the improper fractions to mixed numbers by either using division, mental math, or decomposing the fraction into wholes and parts. It always makes me proud to see students using more than one method!

Next, students compare the mixed numbers to the ranges labeled on the snow globes. This is where the wheels start turning in their heads! Since many snowflake values are close to more than one snow globe range, students must think carefully about where to place the snowflake. Hearing my students make justifications as to where they place their snowflakes, and the conversations that result gives me valuable feedback. 

improper fraction snowflake sort

Once all 48 snowflakes have been placed in the appropriate snow globes, the sort is complete! Even though students work independently with their snowflakes, it feels like a team effort. Therefore, we celebrate together when finished!

Assessing and Advancing Understanding

There’s no doubt this resource can serve as a great assessment tool. Throughout the activity, I use questioning strategies to assess and advance their understanding of the skill. For instance, if I see a student place a snowflake in the wrong snow globe, I’ll simply ask them to share their reasoning. I can also give students small prompts without revealing the answer to help steer them in the right direction.

In addition, I make sure my struggling students are working with simpler fractions and my advanced students are solving more complex ones. This helps to avoid any potential frustration and allows everyone in the group to feel successful.

For my early finishers, I often take it a step further by challenging them to convert improper fractions to decimals. This is proof that differentiating activities doesn’t have to be time-consuming!

Extensions

Once all snowflakes have been sorted, you can give students one more task to complete. Have them each take eight snowflakes, set up four fraction comparison problems, and write in the correct symbol. This can be their “exit ticket” from your small group table.  

Another extension is to have students place the improper fractions on a number line labeled 0-4. You can easily create this number line by using a dry-erase marker on your table.

Do yourself (and your students) a favor and try this hands-on, festive, and engaging activity in your classroom. It has been updated to include number lines on the snow globes, making it easier for students to understand.

Christmas Math Crafts That Help Spread Holiday Cheer

December 9, 2018 by Krejci Creations

“O Factor Tree, O Factor Tree, your factor pairs are lovely.” I know those aren’t the traditional lyrics to the song, but they are the lyrics to my FAVORITE Christmas math song, “O Factor Tree”, by yours truly! More on the song later 🙂

A Holiday Tradition: Christmas math Ornaments

These Christmas factor tree ornaments are an annual tradition of mine. As a math teacher, I don’t get to incorporate crafts into my lessons very often–which is fine because I am the LEAST crafty person I know! 

christmas factor trees

Regardless, I look forward to creating these every year with my students. It’s the perfect Christmas math craft for the not-so-crafty person. 

If you’re looking for a low-maintenance, Christmas math craft that reinforces math concepts, you will LOVE these factor tree ornaments!

Getting Started with Christmas Factor Trees

First, I teach my students about prime factorization. Since they’ve already learned about prime and composite numbers, this is a fun extension for them. After modeling a few examples, I introduce the lyrics to “O Factor Tree”, and we sing the song to an instrumental version. It’s my favorite part of the whole activity!

christmas factor trees

Next, I give students the first page of factor trees which we complete together. I then allow them the option to choose their own numbers on the second page. It’s fun to see students challenge themselves with really large numbers! When finished, they glue these pages in their math journal for future reference.

Next, I go through the instructions on how to create their Christmas factor trees. I’ve learned it’s best to design and color the trees and ornaments before cutting everything out.

Finally, I assemble all of the materials on my teacher table and have students grab what they need. To save time, I copy the trees double-sided so one side is blank and one side includes the lyrics. 

christmas factor tree materials

As a result, each student only needs one tree, 6-12 (two rows) of ornaments, and presents, which can be optional.

 

Another option is to copy the trees single-sided. In this case, each student needs 2 trees, one blank and one with lyrics that they will glue together. Either way works well!

Now they are ready to create their factor tree. During this time, I play festive music as it lessens the desire to talk and adds to the overall excitement of the activity.

How to Differentiate Christmas Factor Trees

There are several ways to differentiate this activity. Allow students to choose their own number. This is differentiation in itself! In addition, challenge your students to create presents under the tree showing the standard form of prime factorization, with or without exponents. Each tree will be unique, and students will take pride in their creations.

christmas factor tree low prep version

Want to cut down on materials and class time? Use the low-prep version where all student materials are on one page. I ended up using this version during my last few years.

Teacher Tips

It’s important that students tell you what number they are factoring before they begin. Some factor trees will be too large to fit on the tree, and some might look too small. Therefore, students should consider the number of ornaments they will need before beginning. Also, because the ornaments can be a challenge for some to cut out, I prepare a handful of them beforehand just in case.

Christmas math ornaments

Once students have cut, colored, and glued their factor trees together, the trees are ready to be made into ornaments. To do this, I hole-punch the star and tie a piece of string, yarn, or pipe cleaner around the hole.

I then display the finished products outside my classroom for the weeks leading up to Christmas Break. It’s so fun to see all of the unique and creative designs the students come up with! 

On the day before break, they take them home to hang on their own Christmas trees for years to come.

Ready to start your own tradition of making Christmas factor trees?  I hope the answer is YES!

8 Helpful Tips for Teaching Long Division

November 11, 2018 by Krejci Creations

i survived long division

Long division is one of the most difficult skills to teach. What other math skill requires students to think about division, multiplication, subtraction, and comparing numbers all within a single problem?

Here’s the thing. I know students will eventually have that “aha moment”. The challenge is preventing them from getting frustrated and giving up. I tell them daily I don’t expect perfection, but I do expect progress. So we shoot for that: progress.

Here are a few tips to help you teach long division without any tears from students…or from you!

Tip #1: Focus on a Growth Mindset

My first tip doesn’t have anything to do with the long division process, but it is a must. When I hear students say they don’t understand, I make them add a very important word–YET! Teaching students to have a growth mindset instead of a fixed mindset is key. They need to realize mistakes help them grow.

Class Dojo has amazing videos that reinforce the importance of this concept. I’ve been showing these videos weekly and have had wonderful discussions with my students about growth mindset. Sometimes they need a pep talk from someone other than me!

One of my favorites is called The Incredible Power of Yet. This short video will inspire your students to conquer long division!

Tip #2: Begin with a Hands-On Approach

It may be tempting to start with a cute acronym (Does McDonald’s Sell Cheeseburgers?) and then begin drilling the steps repeatedly. While I’m not opposed to the acronym, I’ve learned you must first begin with a hands-on approach.

long division base 10 blocks

Students need to know the meaning behind the steps. Why do we compare the remainder to the divisor? Why do we bring down the next digit? They won’t understand this without seeing it first.

Therefore, on day one, I help students model the process with base 10 blocks. We have deep conversations about what each part of the division problem means and why the steps are in the order they are. As a result, students begin to understand the true meaning behind the algorithm.

Tip #3: Teach the Box Method First

I want to kick myself for not teaching this method years ago. The “box method” prepares students to learn the algorithm but presents the steps in a simpler, more organized manner. I teach this method first and work up to dividing a 4-digit number. Here is a video of an example in action.

After students master this method and comprehend the steps of long division, I move to the algorithm.

box method long division

I am amazed at how quickly students understand the algorithm on the FIRST day! This was not the case when I didn’t teach the box method. Back then, long division was frustrating to teach and frustrating for students to learn. It took DAYS for them to grasp this concept. Now students have a choice and can pick the method that works for them.

In the end, most of my students prefer the algorithm. For the rest, I’m so thankful they have a backup method that fits their needs and helps them be successful. You can find this FREE WORK MAT HERE!

Tip #4: Use a Long Division Guided Work Mat

 

Because there are so many steps, long division can be an overwhelming process to learn. That’s why I make sure to check in with students frequently. I want to know what part is clear and what part may be confusing to them.

The most common problem they express is not understanding where to place the digits. Guided work mats can be helpful when students struggle in this area. I created these to use with my students and recently added the place value chart for students to gain a better understanding of what long division means. This work mat has been extremely beneficial and is something I recommend trying if your students are having difficulty with long division.

Try a FREE SAMPLE to see for yourself!

Tip #5: Create Long Division Challenges for Students

It’s easy to spend most of your time helping students who are struggling, but you can’t ignore those who master long division early. Be sure to create a few challenges for those students as well. Mine love my LOOOOOOONNNGGG DIVISION challenge where they can attempt to see how many digits they can divide. It has become quite the competition! By the end of the unit, my entire outside wall is filled with division problems from floor to ceiling!

Tip #6: Go Digital with Boom Cards™

Since much of our current and future testing will be online, students need exposure to digital resources. Those who are just getting the hang of long division by hand may struggle with transitioning to a digital platform. Therefore, it’s important to be selective when going digital.

My favorite digital resources are Boom Cards because of their unique guiding nature and self-checking component. Curious about these digital task cards? Read this blog post which explains how I use Boom Cards in the classroom!

https://krejcicreations.com/wp-content/uploads/2018/11/video-preview-1.mp4
https://krejcicreations.com/wp-content/uploads/2018/11/Video-Preview-1.mp4

After a few days of practice, I assign students my Long Division Boom Cards. Students who have mastered long division work through these with ease and are able to move on to the Long Division Challenge. Students who struggle still benefit because of the self-checking feature. As a result, students learn from their mistakes, something other digital resources don’t always have.

The Bright Bunch has this to say about my Long Division Boom Cards-“My students were much more engaged while using this than a typical worksheet, and the fact that it collects grades – wow!”

Sample a few Long Division Boom Cards yourself! Not sure your students are ready for 2-step division? Try practicing with 1-step division first.

Tip #7: Listen to Your Students

When you see students struggling, refrain from automatically telling them what to do next. Sit down and listen to what they have to say. Ask them what parts of the process are clear and what parts are still confusing. Every student is different!

Tip #8: Be Patient

It’s called Long Division for a reason…sometimes it takes students a LONG time to grasp. But hang in there. It is so rewarding when they finally succeed!
