We need to arrange the students in to groups.
Teal Elementary has 21 students.
Beige Elementary School has 28 students
This is a GCF problem because we need to divide the students into groups.
The kids move on to the next problem after a few minutes.
A group of kids finish solving a problem every 30 minutes. Another group finishes solving a problem every 45 minutes.
When will both groups finish solving a problem at the same time?
This problem is a LCM problem because we need to fins when both groups will finish the problem at the same time.
