Introduction
This is a short list of some of the flash-based interactivities I have made available to play online from my websites. I'm in the process of re-writing a lot of these with Scratch, read my Math Games weblog and interactivity weblog.
Popular Math Games Online
- The Frog Puzzle Online - Click on the lily pads to make the frogs move across the pond by hopping or sliding. Can you work out how
many moves you would need to shift any number of frogs?

Matches - A series of flashcard/concentration puzzles -
sometimes with an added interactive twist. Covers a wide range of
mathematical topics. Add your own, if you want.
- Interactive 100
Square Chart - Investigate patterns made by multiples of numbers in a 100 square. If that's too easy, try the n-square
investigation.

tessellations and Islamic Patterns.
Linking Policy
Many teachers find it much easier to link directly to specific puzzles online, rather than direct their students to this index. Feel free to do this from your own classroom webpage.
Number Puzzles
- Magic Square, Magic Triangle 1 and Magic Triangle 2 - The first three of a series of number puzzles. Drag the numbers onto the red circles to make the rows, columns and diagonals all add up to the same total. A more polished and extended version will appear on the Math Games website in October 2009.
- Magic Stars (1), Magic Stars (2) Two more from a series of number puzzles. Drag the numbers onto the red circles to make the sums and products of two sets of four numbers the same. A more polished and extended version will appear on the Math Games website in October 2009.

Quiz - answer the simple addition questions. Correct answers
colour the picture in.
- Crossnumber
- Add the 5-digit numbers together to give you the answers to the
clues in this crossnumber puzzle.
- Odd
One Out - Decide which calculation is the odd one out because it has a different answer to all the others. I was quite pleased with this mathgame, because it requires a little more thought that your standard arithmetic drill based on the four rules of number. I'm thinking of putting together a set of simpler versions of this puzzle for younger students.

questions in a row correctly.

old bomber arcade game - updated into an online mathematics drill. Drop
bombs on skyscrapers to answer multiplication table questions. For
those who prefer their mindless carnage online, there is also a retro version of
the original Bomber game.

multiplication signs to make a target of 100 in as short a time as
possible.

- 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.
- Pie
Test - Estimate the size of the sector of the pie chart which has
been shaded yellow..
