You can earn coins and spend them in the virtual shop, challenge other people (including children from other classes or teachers) and you can battle in the arena. Well done to Jack, Laura, Harlow, Freya, Nikita, Jessica, Jacob and Lauryn who have already been on it during the school lockdown.

 

Nikita has won the most coins -  who can catch up with him in April?

Year 3 Maths

Subtraction

To help pupils to subtract accurately, we encourage them to use a written method. We teach column subtraction. Pupils have been taught this already in year 3 but here is a reminder below.

 

Column subtraction showing regroupingIn this example of column subtraction, it is easy to subtract the ones: 7 - 3 = 4
It is not possible to subtract the tens though: You can't subtract 4 from 2. (If I have 2 apples, you can't take 4 of them!)

So, we regroup the hundreds. We take one of the hundreds and put it in the tens. Now there are 12 tens: 12 - 4 = 8

Last of all, subtract the hundreds. (Remember there are only 4 hundreds left now). 4 - 1 = 3

Addition

This is how we add large numbers in year 3 at Morland (some parents may have learnt a different way but try to stick to this method.)

 

Always start with the right-hand column, the ones:

8 + 7 = 15

We can't put 15 in the ones column (only one digit is allowed in each column).

15 is made of 10 and 5, so we write the 5 in the ones. 10 can go above the tens column, but because it is 1 ten we write just a 1.

Next, we add the tens (don't forget that extra 1)

1 + 5 + 3 = 9

Last of all, we add the hundreds: 4 + 1 = 5
