Lesson 2 How Many in Each Group?

    • Let’s represent and solve more problems.

Warm-up Notice and Wonder: More Apples

What do you notice? What do you wonder?

An apple orchard.

Activity 1 How Many Apples?

Solve each problem. Show your thinking using objects, a drawing, or a diagram.

  1. If 20 apples are packed into 4 boxes with each box having the same number of apples, how many apples are in each box?

  2. If 36 apples are packed into 6 boxes with each box having the same number of apples, how many apples are in each box?

  3. If 45 apples are packed into 9 boxes with each box having the same number of apples, how many apples are in each box?

Activity 2 Gallery Walk

Visit the posters around the room with your partner. Discuss what is the same and what is different about the thinking shown on each poster.

Activity 3 All the Apples

If 24 apples are put into boxes with 8 apples in each box, how many boxes are there?

If 20 apples are packed into 4 boxes with each box having the same number of apples, how many apples are in each box?

Discuss with your partner:

  • How are these problems alike?

  • How are they different?

  • What is alike and what is different about how these problems are represented and solved?
