THE MAKE-TEN STRATEGY

Making Ten is one of the most powerful addition strategies. The idea is simple: break one number apart so that part of it combines with the other number to make exactly 10. Then add whatever is left. Our brains find it very easy to add to 10!

8 + 5

18 needs 2 to make 10

2Split 5 into 2 + 3

310 + 3 = 13

= 13

LEADER TIP

Ten-frames are essential manipulatives. Practice number bonds to 10 daily until they become automatic.
