Middle Grades Math: Using Venn Diagrams to Find the GCD

In this activity, students use Venn diagrams to sort data. Specifically, students use the diagrams to analyze the factors and multiples of different numbers.  In the screenshot, the constant is +6.

Students use the lcm( and gcd( features to investigate the number relationships in the Venn diagrams. Also, to find the factors of the three numbers given, students can use the integer division and remainder features to show the actual remainder from the division.
