Ordering decimal numbers- an ICT activity to target misconceptions.

This resource contains an EXCEL spreadsheet that ‘builds’ decimal numbers out of units, tenths and hundredths and allows pupils to compare them and sort them in order of size. There is also a worksheet which gives sets of numbers to order; pupils are directed to try ordering these, then feed the numbers into the spreadsheet and see if they were correct. You can use the spreadsheet with or without the worksheet, or think up your own activities for pupils to do. The sets of numbers given on the worksheet are designed to target as wide a range as possible of these misconceptions.
