One of the “games” from our math curriculum was to play a little addition/subtraction game using playing cards. We loved it so much that I made a little game board to go along with it!
Once you have made your two equations, remove the cards, set them aside and continue turning over cards from the stack until you are able to make another equation. This process {practice} continues until all the cards in the deck have been turned over and there are no more possible equations to be made.
FYI, though we haven’t really used it yet, I did include a multiplication/division game board in the download as well!
