# Why your child should know Doubles Facts while theyre young

Jul 8, 2022 | Upper Mount Gravatt

Numerical Fluency includes knowing doubles facts, and kids should learn about it from Prep. At this level, they should understand doubles facts of basic numbers: from 1+1 to 5+5, plus 10+10. And when they’re in Year 1, they should know from 1+1 to 12+12.

Learning doubles facts - or maths in general - with manipulatives allows students to move from concrete experiences to abstract reasoning.

Learning doubles facts through playing is learning the fun way!

Why does a younger student need to know double facts? It will help them to expand their maths skills to more complex maths problems.

1. It helps them do sums over 10 such as 6+7 or 9+8 by using doubles and plus or minus 1.
2. If they’re able to do doubling, they would know halving; for example, half of 14 is 7. And when they’re progressing to half of odd numbers, they would know that half of 19 is 9 ½ because 19 is 18+1, and half of 18 is 9, and half of 1 is ½ so you would add them together to get 9 ½.
