Lost on Alpha Prime
Stage: 4 Challenge Level: 
On the 3D grid a strange (and deadly) animal is lurking. Using the tracking system can you locate this creature as quickly as possible?
Pick's Theorem
Stage: 3 Challenge Level:
Polygons drawn on square dotty paper have dots on their perimeter (p) and often internal (i) ones as well. Find a relationship between p, i and the area of the polygons.
Eight Hidden Squares
Stage: 2 and 3 Challenge Level:
On the graph there are 28 marked points. These points all mark the vertices (corners) of eight hidden squares. Can you find the eight hidden squares?
Areas of Parallelograms
Stage: 4 Challenge Level:
Can you find the area of a parallelogram defined by two vectors?
Square Coordinates
Stage: 3 Challenge Level:
A tilted square is a square with no horizontal sides. Can you devise a general instruction for the construction of a square when you are given just one of its sides?
Completing Quadrilaterals
Stage: 3 Challenge Level:
We started drawing some quadrilaterals - can you complete them?
Vector Journeys
Stage: 4 Challenge Level:
Charlie likes to go for walks around a square park, while Alison likes to cut across diagonally. Can you find relationships between the vectors they walk along?
Opposite Vertices
Stage: 3 Challenge Level:
Can you recreate squares and rhombuses if you are only given a side or a diagonal?
Cops and Robbers
Stage: 2, 3 and 4 Challenge Level:
Can you find a reliable strategy for choosing coordinates that will locate the robber in the minimum number of guesses?
Coordinate Patterns
Stage: 3 Challenge Level:
Charlie and Alison have been drawing patterns on coordinate grids. Can you picture where the patterns lead?
Square It
Stage: 3 and 4 Challenge Level:
Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.
Beelines
Stage: 4 Challenge Level:
Is there a relationship between the coordinates of the endpoints of a line and the number of grid squares it crosses?
Doesn't Add Up
Stage: 4 Challenge Level:
In this problem we are faced with an apparently easy area problem, but it has gone horribly wrong! What happened?
Tilted Squares
Stage: 3 Challenge Level:
It's easy to work out the areas of most squares that we meet, but what if they were tilted?
Route to Infinity
Stage: 3 Challenge Level:
Can you describe this route to infinity? Where will the arrows take you next?
