So here’s a game to get kids to know how algebraic signs work:
Give each student a card with a plus (+) or a minus (-) sign on it, and give them a blank card. The first person in each row passes their card to the one behind, and that kid will have to figure out which sign is the result of the combination of the one they got and they one they had. Write the answer on the blank card, and pass on that answer card. The game continues until the last person in the row has the final outcome of the signs.
Then we’ll review and see on the board what the answer actually was. The winning row gets points.
I think there are more games where this one came from 🙂
