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
