Here are a few of my favorite ones.
Domino Keepers Addition
a game for 2 players (or two teams)
All of the dominoes are placed in the centre face down.
Both players pick up a domino at the same time.
Each player tells the sum of the dots on their domino, e.g. 2+4=6, 5+3=8.
The player with the highest answer keeps both dominoes. If both players have the same answer, each keeps a domino. The winner is the player or team with the most dominoes when all dominoes have been picked up.
Domino Keepers Multiplication
a game for 2 players (or two teams)
Play this game as above but instead of adding the two numbers on the domino, multiply them.
These games tick all of the boxes - the kids love them, they are simple to play and all you need is a set of dominoes!
