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.
Areas from Vectors Stage: 3 and 4
Use the applet to explore the area of a parallelogram and how it relates to vectors.
Find the Metagiff Stage: 3 and 4 Challenge Level: 
Play the game. How many guesses do you need to find the Metagiff?
Getting Round the City Stage: 3 and 4
In a city with a grid system of roads, how do you get from A to B?
Advanced Mathematics on Dotty Grids liveStage: 4 and 5 Challenge Level:
A dotty grid is a very simple mathematical structure that offers potential for very deep thought...
