TIMS Task

Make sure the story fits the sentence. Use of the numbers 20 and 15 is not a guarantee that the story matches.

Possible story: Hannah wanted to take 20 cupcakes to a party. There were 15 cupcakes already frosted. How many more cupcakes did Hannah need to frost?

B. Number Sentence Stories

The number sentence 20 = 15 + can fit a story like this:

Simon wants a computer game that costs $20. He has saved $15. How much more money does Simon need to buy the game?

Write another story for 20 = 15 + and solve the problem.
