Prime and Composite Numbers Bundle: Worksheets, PowerPoint, Craft Activity, Game

This bundle focuses on prime and composite numbers. After defining prime numbers and composite numbers, students will draw factor rainbows to determine whether a given number is prime or composite. It includes a 38-slide interactive PowerPoint that introduces the process in a logical step-by-step manner. It also includes a matching math craftivity, three worksheets, and one game.

38-slide PowerPoint

• It begins with reviewing the meaning of factor and introducing definitions for prime and composite numbers.
• Students are then shown how to create factor rainbows to help them determine if a number is prime or composite.
• I also address two common misunderstandings, by showing how odd numbers are not always prime, and how even numbers are usually composite (the number 2 is the only exception). It includes many practice opportunities.
• The PowerPoint comes with a 3-page matching companion handout. Students write on the handout as you progress through the PowerPoint.

Worksheets and Craftivity

• Students begin by completing two worksheets.
• Then, they use the answers on their worksheet to create their craftivity!
• Each student's craftivity is just a little bit different than their classmates' displays because it is based on their birthdate!
• The finished products can be hung on a bulletin board or in the hallway. They create a fun display!

3 Worksheets and Game

• Worksheet #1: Solve the riddle at the bottom of the worksheet by identifying whether each number is prime or composite. Students also identify the factors of each given number.
• Worksheet #2: Students are presented with eight numbers. If a number is a prime number, he/she writes it on a prime popsicle. If a number is a composite number, he/she writes it on a composite cupcake. Students also identify the factors of each given number.
• Worksheet #3: In Part 1, students are presented with 4 numbers. Three of the numbers are the same classification (prime or composite) and one number is not. Students must choose the number that does not belong in the group, and write a sentence that explains why it does not belong. For Part 2, students are given six numbers. They must identify the factors for each given number and determine whether it is a prime number or a composite number.
• OUCH Game! This fun game is perfect for small groups. Sixty cards are cut apart and spread facedown on a table. Students take turns drawing cards, reading the number, and saying whether it is prime or composite. If they happen to draw an OUCH card, however, all of their cards get put back on the table and they must start over with collecting cards. The first person to get seven number cards wins the game!

Here's what teachers like you have to say about using these prime and composite numbers activities with their students:

⭐️ Ann G. said, "Great resource!! I love everything in this. Students really enjoyed the craftivity."

⭐️ Alisa D. said, "My observation had been rescheduled several times before winter break. The day that worked out for my admin just so happened to be the day I was using this resource. I knocked that observation out of the park and my students had mastery of prime and composite numbers after this lesson and the included practice! "

⭐️ Susan C. said, "My students with learning difficulties were so engaged with this and did very well demonstrating their understanding after we watched the PowerPoint."

⭐️ Ladetra P. said, "This PowerPoint included how to find the factors of numbers and how to identify as prime or composite. It is extremely engaging and interactive."

⭐️ Kimberly M. said, "If you are looking for something to teach Prime and Composite numbers, this is what you MUST get!!!"
