What are the Subtraction Facts?
The subtraction facts are the differences from 2 – 1 up to 18 – 9. Just like the addition facts, the subtraction facts lay the groundwork for the rest of elementary arithmetic. Without thorough mastery of the subtraction facts, your child will struggle as he tackles multi-digit subtraction, word problems, and long division. He’ll use so much of his working memory on simple calculations he’ll have little brain space left for understanding new concepts. This leads to solving problems more slowly, making more mistakes, and an overall lack of confidence in math.
How Fast Should My Child Know the Subtraction Facts?
Immediately is best, but it depends a lot on your child. Children who process information very quickly are quite capable of knowing each fact in less than 1 second, but children who are slower processors may always need a few seconds. As a general rule, aim for no more than 3 seconds per fact, without counting to find the answer. (Why no counting? Learn more here.)
When Should My Child Master the Subtraction Facts?
Children should master the subtraction facts after they’ve mastered the addition facts, ideally at the beginning of second grade. That way, they’re well-prepared to tackle second-grade math topics like word problems and multi-digit subtraction. But, if your older child hasn’t mastered the subtraction facts, it’s never too late.
