What's it worth?
There are lots of different methods to find out what the shapes are worth - how many can you find?
Cinema Problem
A cinema has 100 seats. How can ticket sales make £100 for these different combinations of ticket prices?
Tilted Squares
It's easy to work out the areas of most squares that we meet, but what if they were tilted?
How far does it move?
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the dot affects the distance it travels at each stage.
Semi-regular Tessellations
Semi-regular tessellations combine two or more different regular polygons to fill the plane. Can you find all the semi-regular tessellations?
Opposite vertices
Can you recreate squares and rhombuses if you are only given a side or a diagonal?

Speeding up, slowing down
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the dot affects its speed at each stage.
Product Sudoku
The clues for this Sudoku are the product of the numbers in adjacent squares.
Which solids can we make?
Interior angles can help us to work out which polygons will tessellate. Can we use similar ideas to predict which polygons combine to create semi-regular solids?
