Cycling Squares is superb NRich Maths activity to get pupils familiar with the square numbers. The idea is that the pupils get the worksheet above and have to place the numbers into the spaces in the circle. Each adjacent pair of numbers must add up to a square number.
I have used this activity a lot myself and find that pupils often get all the way around the circle only to find the last two don’t add up to a square number! It is a challenging activity that takes a lot of persistence to solve. The nice thing is that this is a true rich activity; even the lower ability pupils can still get going relatively easily and benefit from it.
As ever, answers and teacher notes are available along with the activity on the NRich website.
