Question 2

Lily has 8 stickers. Her friend gives her 5 more stickers. How many stickers does Lily have now? Choose the number sentence that correctly shows the situation and explain why it matches the story.

Accepted Answer

8 + 5 = 13 – because Lily started with 8 stickers and then got 5 more, so you add them to find the total.

Answer

8 + 5 = 12 – because you add the numbers, but the sum is written incorrectly.

Answer

8 - 5 = 13 – because you subtracted instead of adding, which does not match getting more stickers.

Answer

5 + 8 = 12 – because the numbers are added in the wrong order and the sum is also wrong.
