Number

Addition is...

bringing two or more numbers (or things) together to make a new total.

Here 1 ball is added to 1 ball to make 2 balls:

Using Numbers it is: 1 + 1 = 2

And in words it is: "One plus one equals two"

Subtraction is...

taking one number away from another.

If you have 5 apples

and you subtract 2,

you will be left with 3.

This would be written: 

5 - 2 = 3

Division is... splitting into equal parts or groups.

It is the result of "fair sharing".

Example: there are 12 chocolates, and 3 friends want to share them, how do they divide the chocolates?

12 chocolates

12 chocolates divided by 3

Counting on 
These cards assist children with counting on. The children are able to see how many there is my the written number and how many more they are required to count to obtain the total. Counters are encouraged to be used with these cards to demonstrate a concrete example to the students.

   Doubles
Doubling cards such as these lets the student see how the numeral can double to make a total of four. Children that can not subitise the amount instantly can practice this with doubling cards or die.

Near doubles
Domino cards such as these can be used to show near doubles to children. The difference in colour allows the child to see the near double plus one.
