Your students can practise solving subtraction calculations using friendly numbers with these engaging code creator worksheets.

A range of subtraction problems must be created for another classmate to solve. The classmate will round the first number in each calculation up or down to the nearest friendly ten and then use compensation to find the correct answer. Some of the answers will be circled or highlighted. These numbers must describe the appearance of an emoji when used with the code provided. After solving the problems, the classmate must draw the correct emoji.

Three differentiated versions of the worksheet are available. The first requires two-digit by one-digit calculations, the second requires two-digit by two-digit calculations, and the third requires three-digit by two-digit calculations.

When you have decided which version of the worksheet to give to which students, you can print out the number of copies that you need and start the maths fun.
