## Follow-On Maths

Take a starting number and apply a set of instructions to it to achieve a finishing number.

Click create to generate a new start number and instructions. The start number will not appear. You can choose whether to show the start number or the answer. Showing the answer modifies the puzzle so that students have to do the inverse of the instructions to find the start number.

A timer can be applied. The length of time available for each instruction can be adjusted. When the length of time has passed a light appears below the instruction to show the students that they should move on.

## Square or Prime?

A really really cool interactive game to practise number properties. Thirty particles fall from above. Use the repelling particle to nudge them into the correct box depending on whether they contain a square number or a prime number.

Three thumbs up!

## Lowest Common Multiple Interactive!

A neat visual way to find the LCM (lowest common multiple) of two numbers.

## Animal See-Saw

Animal See-Saw is a game for two players.

Each player is given 12 animals.

Players take it in turns to place an animal on their side of the see-saw - making sure that their side of the see-saw is never more than 5 kg heavier than the other side.

The winner is the player who survives the game without ever being more than 5kg heavier than his/her opponent.

If a player does become 5kg heavier than their opponent, the see saw falls, they lose and the game is over.

If both players make it to the end of the game, the winner is the one with the most weight on his/her side.

Note: This is not a trick question. This is a real math problem so don't say that a bus has no legs. Also, there is no driver on the bus, so don't add any legs for a driver.

There are 7 girls in a bus
Each girl has 7 backpacks
In each backpack, there are 7 big cats For every big cat there are 7 little cats

Question: How many legs are there in the bus?
