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.

The Tower of Hanoi is an ancient mathematical challenge. Working on the building blocks may help you to explain the patterns you notice.
Imagine you have an unlimited number of four types of triangle. How many different tetrahedra can you make?
How many more miles must the car travel before the numbers on the milometer and the trip meter contain the same digits in the same order?
Can you find a cuboid that has a surface area of exactly 100 square units. Is there more than one? Can you find them all?
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the dot affects its vertical and horizontal movement at each stage.
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?
Can you find the pairs that represent the same amount of money?
