There are 2 worksheets with 10 questions each. The questions in the first worksheet come with clues to guide the student.
Questions 1 to 6 have fully worked answers, with clear explanations. They should be used to facilitate student discussion and analysis. They are not meant to be the one and only correct method of answering the questions.

Questions 7 to 10 also have step-by-step working but no detailed explanations. Again they should be used to facilitate student discussion.
A second set of worksheet, with blanks for students to fill in, is included to be used as a template for students to create their own worksheet.
There is no better way for students to fully understand how to use the four operations than to write questions that can be solved.
As students discuss and try to solve each other’s worksheets, they will gain confidence. This will also help them to better analyze and solve difficult questions during exams.
