Headline Story
Jon has more marbles than Tyler. Jon and Tyler each give the same number of marbles to Ben.
Possible student responses
- Jon still has more marbles than Tyler.
- Ben might have more marbles or fewer marbles than either Jon or Tyler.
- If Jon starts with 20 marbles and Tyler starts with 18 marbles and they each give 10 marbles to Ben, then Ben has 20 marbles, Jon has 10 marbles, and Tyler had 8 marbles.
- Jon might still have the most because if Jon had 20, and Tyler had 18 and they each gave 3 to Ben, then Jon has 17, Tyler has 15, and Ben has 6.
