Prime and Composite Numbers PowerPoint Lesson with Practice Exercises

Are you searching for a step-by-step PowerPoint that can be used to introduce prime and composite numbers to your students in a way that will grab their attention? If so, this highly interactive 37-slide PowerPoint may be exactly what you are looking for! Students are taught how to make factor rainbows to determine if a number is prime or composite. Several practice opportunities are provided.

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).

***A 3-page PowerPoint companion handout is also included in this file. Students can follow along and record answers on this handout as you progress through the PowerPoint! The companion handout is available in both printable format or digital format.**

PowerPoints filled with visuals are ideal for teaching new content to students because PowerPoints tend to be highly engaging and concepts can be easily broken down into understandable chunks of information. But let's face it... they are so time-consuming to create! Fortunately, now you have an option of using one that is already complete, kid-tested, and ready to go for you!
