Description
Our Prime/Composite Numbers lesson helps students distinguish the difference between prime and composite numbers, and how knowing and identifying them can help them with mathematical operations. It is important for students to explain why prime and composite numbers are not the same as odd and even numbers. Students are asked to play a prime/composite game with a partner in which they create their own factor trees and the student who correctly completes their tree and circles all prime numbers first wins. Students are also asked to individually complete practice problems in order to demonstrate their understanding of the lesson.
At the end of the lesson, students will be able to define prime and composite and identify prime and composite numbers and explain their use for mathematical operations.
