Explain how you used the bar model in exercise 2 to solve the problem

Grandma has 14 red roses and 7 oink roses. How many mo re red roses than pink roses does she have.

We are given that Grandma has 14 red roses and 7 pink roses.

In order to represent them on bar modal, we need to make a bar with 14 identical sections for 14 red roses.

And for pink roses, we need to make a bar with 7 identical sections for 7 pink roses.

From the bar graph, we can see that bar for red roses have 7 more boxes than bar of pink roses.

Therefore, she have 7 more red roses than pink roses.
