Pyramid Maths


When the Cat's away, the Mice will play.
While the Year 4s were away, the Year 3s had a play.   The kids in Room 10 for maths made a pyramid and learnt more about ARRAYS and MULTIPLICATION.  

We started with a 9 X 9 base, then added an 8 X 8 layer, followed by 7 X 7, until finally we placed a single block on top. 

We talked about squaring numbers and tried to remember some of them.

  2. Isn't it cool that if you subtract each of the totals from each other starting from the '1' they are all of the 'odd' numbers! (1,3,5,7,9,...)
