Charts for Prime and Composite Numbers

Do your students have a solid understanding of prime and composite numbers? Can they explain what makes a number prime and what makes it composite? If your students need a little more help with this topic, or if you are looking for some math printables to use in your classroom, you have come to the right place! 

Teach Starter has created a set of prime and composite posters to use in your classroom today! Each poster is beautifully decorated and highlights either prime or composite numbers. Students will also find the definition of a prime and composite number.

Choose your favorite theme to use in your classroom! This resource has the posters in 3 different themes, including:

• Boho rainbow
• Muted rainbow
• Bright rainbow

How to Make the Most of Your Prime and Composite Numbers Poster Pack

1. Print the posters and display them in your classroom for students to reference when doing independent work.
2. Print the posters, slip them into a clear sleeve, and use them in your guided groups as a reminder.
3. Print the posters, slide them into a clear sleeve, and hang them on a ring as a reference tool for a learning center. 

We’ve also come up with bonus ways to turn posters into interactive tools that really make your lessons stick!

📝 Create a fill-in-the-blank worksheet by removing selections of text.  

📂 Place copies in students’ homework folders for reference. 

💻 Provide posters as digital resources for virtual students. 

🧠 Test students’ memories by showing them the poster, then hiding it and having them tell you what they remember.

✅ Incorporate posters into your lesson wrap-up: students write on a sticky note what they learned from the lesson and place it on the poster.
