How many Worksheets in each Set ?
Virtually unlimited At the click of a button all numbers are randomised, so the questions change every time.  This will allow you to create as many new worksheets you will need for practice throughout the year (classwork, homework, revision etc) or even give small groups of students in your class different sets of questions either at the same level or differentiated .

As these worksheets  need little explanation, they are ideal to leave work for a replacement teacher.

Answers can be found on the second page of every worksheet, automatically generated when you create a new worksheet.
