Topic F: Reasoning with divisibility

Topic F includes lessons 22-25. "Find factor pairs for numbers to 100, and use understanding of factors to define prime and composite. Use division and the associative property to test for factors and observe patterns. Determine if a whole number is a multiple of another number. Explore properties of prime and composite numbers to 100 by using multiples." Eureka Math/EngageNY (c) 2015 GreatMinds.o
