Turning coins

Aim: Investigate the factors affecting the number of 2p coins that can be turned over in 10 seconds.

Objective: To have an opportunity to compare data and calculate mean, median, mode and range of the data collected.

Year 6

Turning coinsPlace 10 2 pence coins in a row along the edge of a table, with approximately a finger’s space between them.

Turning coinsWork in a group of 2 or 3, one timing 10 seconds, one keeping count and one turning.

Turning coinsTurn the coins one by one, with the fastest hand from Year 5 first. Make sure that you go back to the start of the row after turning ten coins, and don’t work your way back.

Turning coinsWhat about a practice turn first ?

Turning coinsDon’t forget to record your results on your personal worksheet.

Turning coinsNow you need to find the mean, median, mode and range of the number of the coins turned over.

20, 26, 26, 21, 19, 24, 25, 26, 20, 22, 25, 21, 18, 22, 24, 21, 19, 27, 28, 26

18, 19, 19, 20, 20, 21, 21, 21, 22, 22, 24, 24, 25, 25, 26, 26, 26, 26, 27, 28

Mean460 ÷ 20 = 23

Median22 + 24 = 23 2

Mode26

Range28 – 18 = 10
