A brilliant maths investigation focusing on working out how many squares there are on a chessboard. Can be used in any year group, however I have had most success in upper KS2/grades 4-6. Looking at problem solving and working systematically to spot mathematical patterns, the pupils may be able to identify the link with square numbers.
The PowerPoint is very clear and works through the investigation step by step - however, the children get plenty of time to investigate independently. The PowerPoint includes an 'Odd One Out' maths starter and 'Self Assessment/Next Steps' at the end of the lesson.
