Exploring dotty grids at upper secondary
The problems below are all taken from our recent dotty grids resources for Lower Secondary students. We've chosen to feature them on the Upper Secondary page because they all have scope for some interesting mathematical investigation at a higher level. We invite you to explore the problems and then send in your thoughts via Advanced Mathematics on Dotty Grids.
An Appearing Act Age 11 to 16
Cut out and reassemble the pieces. Can you explain what happens?
Areas from Vectors Age 11 to 16
