Go Fish! Number Bonds Version

Our youngest is doing Singapore Math 1 this year and is learning number bonds now. Number bonds, are simply sets of three numbers—two parts and a whole—that go together, like 3, 2, and 5. They are usually represented something like this:

When children learn this one number bond, it becomes easy for them to memorize the fact family 3+2=5, 2+3=5, 5-3=2, and 5-2=3. It also helps later to be able to break numbers down to make them easier to work with.

On to the game. My little guy brought out his set of Go Fish cards last night after dinner and we decided to play "Go Fish to Make 10." (We could have decided to make any number.) You've probably got the idea already, but instead of fishing for pairs of identical cards, you fish for pairs that make 10. For example, if you have a 3 in your hand, you ask for a 7. Don't forget before playing to pull the cards out of the deck that won't work. Last night we had to take out the 11s and 12s.


Above is the Numbers Go Fish Game that we have [amazon affiliate link]. The cards are large and sturdy, the numbers are clear, and the pictures are interesting. A regular deck of playing cards works fine too, but I like having zeros and ones (not aces).

It's nice to have another game to practice number bonds and fact families. I've previously written about others like Salute, Eleven, and Number Bonds Dominoes. All you need for these games is a deck of cards or some dominoes. Please share your favorite ways to practice number bonds in the comments area below!

Math Game: Use Dominoes to Practice Number Bonds

A fun, hands-on math game to practice number bonds, or fact families, is with dominoes. First choose a sum that the dominoes must add up to. I usually use the number ten for double-nine dominoes.

Then place all of the dominoes face down and mix them up. Turn one domino face up. The first player draws a domino and if one of the sides of her domino plus one of the sides of the face-up domino add up to ten, she places her domino next to the face up domino and says, for example, "six and four make ten." Whether she can play her own domino or not, play passes to the next player. This game starts slow sometimes, but it picks up quickly and students end up scanning the table for all possible number bonds that add up to ten.

What I like about this game is that it is fun for any number of players, correction is immediate because the other players are watching, players are thinking mathematically while waiting for their turn, and once several dominoes are on the table, there are several possible correct answers for each turn.

Another fun game to practice number bonds is Salute. Also be sure to check out a page full of math games to play with UNO cards.
