Today in Maths we have been counting forwards and backwards in steps of 4 and 8.

Isabelle really impressed Miss Roberts because she said,

“The number 45 is a multiple of five and if I keep counting in fours Iwill have one left over.”

Explain how Isabelle knew this.

Does anyone know the special word for a number that is left over?

How many squares can you make on a chess board?

Today we have been investigating how many different ways you can make a square on a chess board.

At first we thought it was 64, but it turns out that there is a lot more.


What if….

  • What if the grid was 12 x 12?
  • What if the grid was any number x any number?
  • Can you find a rule to apply to all grids no matter what the size so that no one has to count any more squares?
