From the *Investigations 3* curriculum, which Brookline will begin adopting in the 2020-2021 school year. You can play this game online, too!

**Materials**

*If you don’t have cards around, you can either print them or check out some creative suggestions for alternatives from the kids in 3M*

• Something to cross off or cover the numbers on the bingo board (e.g. pencil, pen, coins, etc.)

**Directions**

- Turn over one 0–20 card.
- Figure out the results of adding and subtracting 9 to/from that number.

11 + 9 = 20 11 – 9 = 2 - Cover one of the answers on your gameboard. (If both are already covered, discard the card, and turn over a new card.)
- Place the 0–20 card in the discard pile.
- Continue playing until all numbers in one row are covered. The numbers can go across, down, or corner to corner .
