This is a short list of 20 of the interactivities I have produced. New interactivities are added every week.
But this list no longer gets updated. If you want to see the
latest collections of my work, visit my Mathematical
Interactivities or join the Interactivities
Forum to learn how to make your own interactive
educational multimedia resources.

Matches - A series of flashcard/concentration puzzles -
sometimes with an added interactive twist. Covers a range of
mathematical topics.

really repeated subtraction.

cruncher around the screen, collecting multiples as you move.
- Percentage estimation - try to
estimate what percentage of the bar has been shaded. Score 3 marks
for being spot on. 2 for a very close answer, 1 for a fairly close
answer.

- Flash Algebra - is it an algebra lesson about Flash, or a Flash

successes out of 20 trials be? Use this interactivity to find the
answer to this and other questions.
