Stick on to card and then cut out the pie chart pieces and cut a slot down the dotted line. Slide the two pieces together along the slots so that half a light grey and half a dark grey pie chart is showing. Rotating the pieces will allow more or less of each shading to be revealed.

The pie chart game

The mean game

Maths focus: Become familiar with interpreting pie charts.

Maths focus: Begin to find the median and mean of a set of data.

Number of players:

Number of players: two to four.

What you need: • One Pie Chart piece for each player (copied onto card and cut out) • Percentage spinner to make a spinner (see How to make a spinner). • Pencil and paper.

E L

What you need: •The Data board. •A set of counters for each player. •A calculator for each player.

P M A Instructions

1 Aim is make a set of data that has a mean close to 15.

Instructions

1 Aim is to have the largest percentage of a pie chart at the end of the game. 2 Cut along the dotted line on the Pie Chart pieces and slot and twist the cards together to make one circle. Adjust the pieces so that half of the circle is light grey and half is dark grey.

2 Players take it in turns to cover 1, 2 or 3 numbers on the Data board. They write down the numbers that they have covered. 3 Once all the numbers are covered, all players calculate the mean of their data set.

4 The player whose mean is closest to 15 is the winner.

S

3 Each player starts with 50% of the pie chart. They choose which side is their side of the chart and write down 50%. 4 Players take turns to spin the spinner and slide their side of the pie chart to add on the percentage shown on the spinner. (The intervals on the Pie Chart Pieces equal 5%) Both players write down their new percentage of the pie chart. 5 The game ends when one player reaches 100% of the pie chart, or after both players have spun the spinner 10 times. 6 The player with the largest section of the pie chart is the winner.

What you need: • Equally Likely cards (copied onto card and cut out). • 1–6 dice (use Blank giant dice template if required). • The Racing board. • A counter for each player. Instructions 1 Aim is to be the first player to move their counter from the ‘start’ to the ‘finish’. 2 Shuffle the Equally Likely cards. Each player takes a card, the other cards are discarded. 3 Players take turns to throw the dice. If the number showing on the die matches any player’s card, the players with those cards move their counter forward one space on the Racing Board. 4 The first player to reach the ‘finish’ is the winner. 5 counters on their home space and must get both to school, rolling a dice and moving one of their counters the matching number of spaces.
