Number Bond Game

20Number Bond Game

Great idea on E is for Explore. 

2 player game
materials: 4 straws, 6 paper plates (2 large, 4 small), tape

Younger kids - dice and number counters (or paperclips, beans, cheerios, etc.)
Roll the dice, using number counters, kids count out the number they rolled. Then, they place the number counters on the whole plate. They roll again, count out the number with their number counters, and place the counters on one of the "part" plates. Whoever figures out the missing part and places the correct number of counters on the plate first gets a point!

You can also use money. Ex: place one dollar on the whole plate and some coins on one of the part plates. Kids figure out the missing part, counting out coins.

Shake and Number Bond!

Fun activity from Teach Math.CA to help kids with number sense (understanding parts and wholes). All you need is a cup with a lid and two-sided counters (a color on one side and a different color on the other). Kids shake the cup and pour the counters on the table. Then, without flipping any of their counters over, they count how many of each color landed face up. For example, 6 red and 7 blue landed face up, with a total of 13 counters. Six and seven are both parts of thirteen (the whole). Not only does this game help with addition skills, but also with fractions. Have kids write the number bond and fractions for each color.

Note: You could also use ten frames with this game. After kids spill their counters on the table, they place the counters on ten frames. Kids see that 13 equals 1 ten and 3 ones, which helps with place value skills!

Have kids compare their number bonds. One friend could have 9 red and 4 blue. While someone else ended up with 3 red and 10 blue! Kids see various combinations of two numbers that equal the same whole: 13. 

If you want to take the activity further, you could have kids write out the fact family for their number as well. However, this would take the fun out of the game!
