# Why your child should know Doubles Facts while theyre young

Jun 30, 2022 | Red Deer

Numerical Fluency includes knowing doubles facts, and kids should learn about it from kindergarten. 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 grade 1, they should know from 1+1 to 12+12.

Learning doubles facts - or math 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 math skills to more complex math 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.
4. They’ll have a smooth process when learning quartering – i.e. half of half – in grade 3. They would know that a quarter of 60 is 15 because half of 60 is 30, and half of 30 is 15. They would know that half of half of 1 is ¼ or a quarter, because it’s just half of half. Many kids are not aware of that, it is very common to see a sixth grader answer “zero” when asked what is half of half.

So you can see that laying math foundations since your child is young is very important as math is built upon itself, layer by layer, brick by brick. And just like learning a language, the younger they are introduced, the more fluent they will be.

Acknowledge your child’s pace and learning style

Some kids got confused easily when introduced a new concept. We have one student who got mixed up between “doubling” and “halving”, so we need to be gentle and adjust to their pace and learning style. For younger kids, introducing a new concept with manipulatives and games work really well (see pictures above). They can relate much better with real objects that they can see and touch as they’re not abstract like reading and writing numbers on a worksheet. Our centre uses a number of manipulatives for doubling. Not only with pictures like shown below, but also with real objects like a dozen eggs in a carton, 6-pack soda cans, spider and cat toys, big truck ’18 wheelers’, etc. For games, we ask kids to play Tic Tac Toe doubles. Having a “mentor” i.e. an older student to play with is also fun, because both can gain positive experience from that.  For halving, using cookies always work! ðŸ˜Š
