Can you imagine where I could have walked for my path to look like this?

Describe what Emma might be doing from these pictures of clocks which show important times in her day.

Can you create a story that would describe the movement of the man shown on these graphs? Use the interactivity to try out our ideas.

These clocks have only one hand, but can you work out what time they are showing from the information?

Use the interactivity to move Mr Pearson and his dog. Can you move him so that the graph shows a curve?

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects the distance it travels at each stage.

Use the clocks to investigate French decimal time in this problem. Can you see how this time system worked?

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its speed at each stage.

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its vertical and horizontal movement at each stage.

Looking at the graph - when was the person moving fastest? Slowest?

Can you adjust the curve so the bead drops with near constant vertical velocity?

Points off a rolling wheel make traces. What makes those traces have symmetry?

What is the quickest route across a ploughed field when your speed around the edge is greater?

A space craft is ten thousand kilometres from the centre of the Earth moving away at 10 km per second. At what distance will it have half that speed?

Build series for the sine and cosine functions by adding one term at a time, alternately making the approximation too big then too small but getting ever closer.

Boyang worked out the fraction of blackcurrant in each of the drinks to answer this problem.

Congratulations to all of you who submitted a correct solution. Have a look to see if your name has been mentioned here.

Have a look here at some of your carefully "ratioed" recipes to make some bland, and not so bland, cereal bars.

Excellent use of a spreadsheet to help with "trial and improvement", plus good graph sketching to really see what's going on.

This article explains how Greenwich Mean Time was established and in fact, why Greenwich in London was chosen as the standard.

A Short introduction to using Logo. This is the first in a twelve part series.

Logo helps us to understand gradients of lines and why Muggles Magic is not magic but mathematics. See the problem Muggles magic.
