FAQ

Why are number bonds for 10 considered the most important set of facts in 1st grade?

The partners to 10 (1+9, 2+8, 3+7…) underpin the make-a-ten strategy, mental computation with two-digit numbers, and virtually all addition beyond 10.

What is the fastest way for 1st graders to develop automaticity with number bonds for 10?

Daily flash card practice, ten-frame games, and asking 'what goes with __ to make 10?' as a quick class routine builds automaticity rapidly.

How do number bonds for 10 directly support two-digit addition?

When students add 38 + 7, knowing that 8 needs 2 more to make 10 allows them to split the 7 into 2+5, making the computation 40+5=45 — a powerful mental strategy.
