Exploring Dotty Grids at Upper Secondary

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

Find the Metagiff 

Age 11 to 16 Challenge Level:
Play the game. How many guesses do you need to find the Metagiff?
In a city with a grid system of roads, how do you get from A to B?
