GCF and LCM Prompts

Storyboard Text

  • 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.
