Random Student Name is a tool for randomly selecting students from your class. It will select in an unbiased fashion and without repetition until all members have been selected.

Typically Random Student Name is used for deciding 'who will answer the next question', or for dividing your class into random pairs or teams for group work.

At the beginning of the school year teachers can set their class list (up to 32 students). Random student name is easy to edit when students need to be added or taken from your class list. It is also easy to temporarily omit a student from the list in the case of students which may be absent on a particular day.

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.
