Our site is mainly based around the US Elementary school math standards.

Though the links on this page are all designed primarily for students in the US, but they are also at the correct level and standard for UK students.

The main issue is that some of the spelling is different and this site uses US spelling.

Year 5 is generally equivalent to 4th Grade in the US.

What are inverse operations?

Inverse operations are opposite operations. Subtraction is the inverse of addition and division is the inverse of multiplication.

When are children introduced to inverse operations?

When subtraction is first taught in Year 1 , children would probably be encouraged first of all to use a group of objects and take a certain number away from this group. They would most likely also use a number line to count back on. These activities would give them a really firm grounding in the concept of subtraction. Teachers would then encourage them to try to work these questions out in their head. For example, with this question: 14 - 8 = your child needs to start to think: 'What would I add to 8 to make 14?'  This means they are using the inverse operation to work out a question mentally.  

When division is first taught (usually in Year 2) a teacher may use counters to demonstrate what the concept means.  For example: 12 ÷ 3 = The teacher might show 12 objects and then group them into 3 circles in order to make division clear. Once children have got the hang of this, they would be expected to work out the answers to division questions quickly by using the inverse operation – multiplication. In Year 2, they would need to learn their 2, 5 and 10 times tables and the corresponding division facts. So if someone asked them what 30 divided by 5 was, they would need to think: 'What do I multiply 5 by to make 30?'  In doing this, they are using the inverse operation.

Children in Key Stage 1 also need to be aware of the fact that doubling is the inverse of halving.  They should understand that where double 3 is 6, half of 6 is 3.

Using the inverse operation in Key Stage 2

In Key Stage 2, children would be expected to start using the inverse in order to check their answers.  

For example, if they had worked out the following subtraction: 392 - 133 = 251 they would be encouraged to add the 133 and their answer of 251 together to work out if these numbers total 392 (which they don't!).

Equally, if they worked out a tricky division, such as: 672 ÷ 56 = 12 it would be a good idea for them to quickly multiply 56 by 12 to check if the answer was 672 (which it is!).

If they halved a number, such as 652, and got the answer 326, they could check this by doubling it.

Using the inverse operation to solve number puzzles

Sometimes children may be given a question similar to the following: I think of a number. I add 17 to it. I divide it by 2. I end up with 20. What number was I first thinking of? The best way to work this out would be by using the inverse. You would need to start with 20, then multiply 20 by 2 to get 40. Since the original number had 17 added to it to make 40, you would need to subtract 17 from 40 to arrive at the answer, which is 23.
