ALEX Lesson Plans
Subject: Mathematics (6  12) Title: What are You  Prime or Composite?
Description: This lesson is on factors and greatest common factors. The students will view presentations on prime numbers, composite numbers, and prime factorization (some using factor trees).
The students will participate in interactive games on various websites, and discover by using their initials in their name, if they are prime or composite.
Subject: Mathematics (4  6) Title: My Favorite Number
Description: The activity allows students to review many of the number theory concepts. Students will pick a composite number write verbal expressions about the number, find the factors, prime factorization, list multiples, draw a cartoon character of the number, and write a word problem. The purpose of this activity is to be a review of the number theory topics taught during middle school.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
