Oh how I tire of pupils telling me that 0.9 is smaller than 0.21! \nThis excel sheet is a good starter or quick supporting exercise for ordering decimals with different numbers of decimal places.\nIt shows three randomly generated decimals, one with one dp, one with 2, one with 3. The numbers have different coloured backgrounds. Pupils can compete to name the biggest and the smallest, calling out either the number or the background colour.
