Answer is 64. Mum and Dad both used their times-tables to get to the answer of 64 by counting the number of rows (8) and the number of columns (8), ie 8×8=64.

Hamish (Yr 2) counted the number of squares in a column (8) and then counted in 8s across the columns to get to 64.

Audrey (Prep) countered all squares by 2s and got 64.

The answer is 64, I used multiplication,because I saw 8 columns and 8 rows and 8 times 8 is 64.

Well done to Bridget Mihulka of 3/4 for working out the solution!

I drew a chess board and circled all the squares. First the single squares then doubles and so on. I went over some times and my final answer is 204.
