Introduction
Display the Headline Story pictured in the sidebar to children. If children need help coming up with some of the ideas suggested in the sample responses, pose questions such as, “How many grapes could there be in all?” or “How many grapes couldn’t there be?”
Headline Story
Oscar and Maria share a bowl of grapes. In order to share them equally, they have to leave one in the bowl.
Possible student responses
- If they each get 10 grapes and there is one in the bowl, then there are 21 grapes in all.
- If each person gets 8 grapes, then there are 17 grapes in all.
- There could not be 100 grapes in all because each person would get 50 but there would not be one left over.
- There has to be an odd number of grapes to start.
