Making 10: These activities support the kindergarten common core standard: CCSS.Math.Content.K.OA.A.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
This file contains several different ways to teach students the complements of 10.
The rainbow graphic helps students to visualize how to add numbers to make 10. If students follow the colors of the rainbow they can see the numbers that make 10. (0+10=10, 1+9=10, 2+8=10, 3+7=10 etc.) The number 5 is in the middle of the rainbow. It does not have a partner so it uses some of the magic from the rainbow’s pot of gold and doubles itself (5+5=10).
There is a dice game that can be played with a partner, alone or with a small group. Kids roll a dice. Then figure out what number they need to add to the number on the dice to make 10. Students record their answers on a worksheet.
The 10 boxes can be used to play games such as memory or go fish. They can also be used with counters to provide students manipulatives to calculate the complements of 10.
