Supporting grades: 3
Description: Sal uses an array and understanding of multiplication to divide. Created by Sal Khan. What I want to do in this video is to divide it into different numbers of groups. So the first thing I want to do is I want to divide this 24 triangle things into 3 groups and think about how many do I end up per group. So I'm going to divide it into 3 equal groups.
