Addition and Subtraction
Column Method
In Year 3 we use column method for addition and subtraction. Here is a help sheet to show you how to lay this out and answer an addition or subtraction problem.
Multiplication
We use grid method for multiplying 2 digit numbers by 1 digit numbers. Below is an explanation of how to lay this out and use the method.
Times Tables
Times tables are the multiplication calculations for all numbers from 1 x 2 to 12 x 10. They are usually grouped by the number being multiplied. Children begin by learning the 2x, 5x and 10x tables, and the English curriculum requires that times tables and the related division facts are known by heart by the end of Year 6.
Continue to use this at least three times a week. The idea behind Times Tables Rockstars is to improve the children’s recall and fluency – the computer automatically releases new questions accordingly!

You still need to be practising your times tables at least 3 times a week! The idea behind Times Tables Rockstars is to improve the children’s recall and fluency – the computer automatically releases new questions accordingly!
Some children prefer to use Numbergym to practice their times tables rather than Times Table Rockstars and that is absolutely fine. Numbergym does not work very well ontablets but works from a laptop or computer.
We have created a handy sheet to help you login to Numbergym from home. How to login to Numbergym. If you need your child's login details please email either maple or larch classs emails
Part Whole (Cherry) Models and Bar Models
These are used to help children to visualise maths problems and can be used across the maths curriculum.
Part Whole Model
The part whole model shows that numbers can be split into parts. The top circle is always the whole and the two lower circles are the parts. This helps children to see the relationship between the whole number and the component parts and to make connections between addition and subtraction.
When we used it in our money topic for subtraction, it meant that children could more easily subtract the pence as they converted £1 into 100p.
There is a good explantion of part whole models on twinkl
Bar Models
These are used to help children to visualise maths problems and can be used across the maths curriculum.
Pictures of bars are used to represent calculations and word problems. Like the part whole model the top bar is the whole and the bottom bar is the parts. This can sometimes be switched around with the long bar at the bottom.
