This activity has been inspired by the work of John Mason’s More/Less Grids and is almost an exact replication of his original More or Less Perimeter and Area Task.
The original task can be found here with other ideas for adaptations.
I was reminded of these at the Improving N5 Conference on Saturday when Chris McGrane mentioned them in his presentation. Here is a link to his blog: Starting Points.
The activity below would be suitable for upper primary and into secondary. Click on the image below to get a copy of the full PDF with instructions of what to do as well as prompt for things to think about.
If you or your pupils have a go at this activity, send me a photo of their end result and we’ll collate these on the blog for others to see.
Could you adapt this More/Less Grid to promote mathematical thinking in a different area?
