- Use fraction circle pieces to model the problem.
- Is Kathy's estimate correct? Explain your reasoning.
- Exactly how much pizza is left over? Show or tell how you found your answer.
- Write a number sentence that shows how you solved the problem.
Kathy models the problem with circle pieces this way:
“Let's put all the pieces together like we did with the pieces of pizza,” said Romesh. “Now the model looks like this.”
“Now let's solve the problem,” said Kathy. Romesh and Kathy both show a different way to solve the problem.
Kathy's way
I just look at what's missing from the whole. We need one more blue piece to make a unit whole.
Romesh's way
I trade the pink piece for blue pieces so all the pieces are the same color.
