# Week 6 27th Ap - 1st May

SQUARE NUMBERS

Square numbers are numbers that are multiplied by themselves.

You know a number is squared when it has a tiny 2 beside it like this: 3²

3 squared is written : 3²

To find the answer we simply write 3x3 and the answer is of course 9

The reason they are called square numbers because they can be displayed as a 3x3 square like below:

If you count up all the square they equal 9 just like 3x3=9

** TO DO SOME OF THIS WEEKS EXERCISES YOU MAY NEED TO USE THE SQUARED PAPER IN YOUR MATHS BOOK **

TRIANGULAR NUMBERS

Triangular number are best described by looking at the pattern they create on paper:

With each pattern they increase in size by extending the bottom line to form a triangle shape.

CUBE NUMBERS

Cube numbers are like square numbers except they have one more dimension to them, so rather than multiplying them by each other, you are multiplying them 3 times:

3 x 3 x 3

You can recognise cube numbers because they have a tiny 3 beside them like this: 3³

Instead of making a visual 2d square they make a 3d cube
