One of the Mental Math Strategies we learned about is making 10. This is also a very useful strategy for when we begin grouping and adding larger numbers. To practice this valuable strategy, we learned a new card game called Making 10. The players each got 5 cards, and they had to make 10 either using 1 card (a 10 or a face card) or 2 cards (two numbers that add up to 10). Students were to lay down their cards that made 10, then pick up more, and wait for their turn again. Below is a video of Nick and Colby playing Making 10.
