## What Are Doubles?

A double is a number arrangement where the same number is added twice. Learn all about them with these doubles facts.

1. For example, a doubles fact is that the double of 2 is 4 because 2 + 2 = 4.

2. Doubles are a mathematical tool to help young children work towards being able to add numbers automatically.

3. Doubles games and using doubles facts are great for grade one and grade two students to help them understand addition and subtraction more easily.

4. To use doubling in math, you add the same number to itself. For example, the double of 5 is 10 because 5 + 5 = 10.

5. The double of 4 is 8 because 4 + 4 = 8.

6. Children who are able to remember doubles facts in math will be able to manipulate single-digit numbers more effectively and improve their ability to add and subtract.

7. You can practice doubles with flash cards, finger counting or simply by using doubles facts verbally.

## What Are Near Doubles

Once your child understands and has memorized doubles facts, near doubles are a very useful way to take their addition and subtraction skills to the next level.

8. A near double is a maths sentence that is close to a doubles fact.

9. For example, 3 + 4 is a near double as it is just a single digit away from the doubles fact 3 + 3.

10. Near doubles draw on a core understanding of doubles facts, you then add or subtract one to get a final number.

11. For example, if a child has memorised doubling in maths, then, when asked the sum of numbers that are one more or less than doubles, such as 5 + 6 or 3 + 2, they can use doubles facts plus one (or minus one) to get their answer.

12. While children memorise double facts to make addition and subtraction easier, it is important that they understand and explore rather than memorise near doubles facts.

13. The goal of near doubles is to understand the doubles plus one or doubles minus one strategy conceptually so they can apply them to a range of examples rather than only the ones they have memorised.

14. If you hear your child saying things like “I used the doubles plus one strategy to solve this” but they can”t remember what that was, then they probably need some more explaining to get their head around the concept of addition with doubles numbers.

## Doubles Strategy For Addition

Using doubles to add is one of the quickest ways to help your child understand addition facts better and become more automatic when adding single digit numbers.

15. There are basic doubles addition facts that will help your child use doubles to add.

16. Near doubles are also very helpful to use when teaching grade one and grade two students doubles addition.

17. If a child knows 9 + 9 = 18 then using this knowledge, they will understand that 9 + 8 will be one less. 18 – 1 =17.

## Doubles For Subtraction

You can also use doubles math to help your child understand subtraction. Learn how with these facts!

18. By remembering the doubles facts, a child can apply them to subtraction math equations.

19. For example, if the equation is 6 – 3, the child knows that the double of 3 is 6, so therefore, 6 – 3 = 3.

20. For more complicated subtraction, say 18 – 8, the child knows that the double of 8 is 16, and the difference between 16 and 18 is 2. Therefore, they know the answer will be the sum of 8 and 2, which is 10.
