Let’s represent and solve more problems.
Warm-up Notice and Wonder: More Apples
What do you notice? What do you wonder?
Activity 1 How Many Apples?
Solve each problem. Show your thinking using objects, a drawing, or a diagram.
If 20 apples are packed into 4 boxes with each box having the same number of apples, how many apples are in each box?
If 36 apples are packed into 6 boxes with each box having the same number of apples, how many apples are in each box?
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

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?
