This PowerPoint slideshow will help your students determine whether a number is prime or composite. Slides use cute images of beetles, lizards, fish or stars and addition sentences to illustrate the difference between these two types of numbers. The entire slideshow is fully animated (just click on the arrow to advance to the next slide). This lesson is perfect for whole-class instruction. And you can place it on student-computers for independent review as a Math Center.
Take a look at the Preview to see some of the slides in this slideshow.
