The game uses a 3x3 square board. 2 players take turns to play, either placing a red on an empty square, or changing a red to orange, or orange to green. The player who forms 3 of 1 colour in a line wins.

### Yih or Luk Tsut K'i or Three Men's Morris

Some puzzles requiring no knowledge of knot theory, just a careful inspection of the patterns. A glimpse of the classification of knots and a little about prime knots, crossing numbers and knot arithmetic.

## Matching Fractions Decimals Percentages

Match the cards with the same value.
Keep an eye on your score - ending at around 400 would be an excellent score.

To download a printable version of this game, use the links below. There are three sets - set A are the easiest and set C are the most difficult.

If you print double sided, then the cards will have an NRICH logo on the back. Otherwise, you can just print the first page.

### Why play this game?

This game can be played to speed up recognition of equivalent fractions, decimals and percentages.

### Possible approach

There are three sets of printable cards, which you may find useful. Set A is the easiest, and set C is the hardest. Each half (top/bottom) is a stand alone set: you can combine these to form the size and difficulty that you would like. For example, you might want to combine the bottom half of set A with the top half of set B, or all of set B with the top half of set C.

Play the game with the class at the interactive white board, to explain the game and revise the subject.

Ask pupils to play the game on computers, or with printed out cards - seeing how quickly they can clear the cards.

Bring the class together and ask for any tips / strategies / special things to remember that help with the game. Ask if the cards are too easy, too hard, what else could have been on the cards.

Ask pupils to make a memory card game, to practise fraction / decimal / percentage equivalence. Suggest that they make it difficult but not impossible for their class. You could stipulate that pupils' games turn 3 cards on each go, and try to find a matching triple (fraction / decimal / %)

Demonstrate Fraction and Coins Game and Fraction and Percentage Card Game on the interactive white board, to suggest ways to make the game easier / harder.

### Key questions

When you see 0.3, what are you thinking / looking for?
Which cards are easy / difficult?

### Possible extension

Play Fraction Card Game 4 where the card matching requires calculations.

### Possible support

Allow pupils to keep a record of the value of the cards that they have turned.
Ask pupils to design a game with fewer cards, but with the most important facts.
