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.

Age 11 to 16

Cut out and reassemble the pieces. Can you explain what happens?

Age 11 to 16

Use the applet to explore the area of a parallelogram and how it relates to vectors.

Age 11 to 16

Challenge Level

Play the game. How many guesses do you need to find the Metagiff?

Age 11 to 16

In a city with a grid system of roads, how do you get from A to B?

Age 14 to 18

Challenge Level

A dotty grid is a very simple mathematical structure that offers potential for very deep thought...
