I am sure someone somewhere has already come up with this idea but it came to me in class the other day and I wanted to share!
I needed a quick activity the other day to play to reinforce the topic of additive inverse. I came up with the idea of Additive Inverse Go Fish and the kids loved it so here are the rules:
Just like in lots of our other integer card games we made the black cards positive and the red cards negative. I also have a sign in my room that assigns numeric values to all of the “face cards”. We do A = 1, J=11, Q=12, K=13. Each player got 5 cards and was allowed to ask anyone at their table for a certain card. The catch was that in order to lay down a matching pair, the 2 cards had to be each other’s additive inverse. So instead of just asking for a 7 students had to ask for the additive inverse of 7 or if a student had a red 3 they would have to ask for the additive inverse of negative 3. Just like in regular Go Fish if the person you asked didn’t have the card you were looking for you had to draw from the pile. First student to run out of cards was the winner! It was a great and quick way for students to practice up on their additive inverse skills while having fun. I hope you will give it a try!
