E3-L1 How to check your answers with reverse calculations
A good way for learners to understand the importance of using reverse calculations to check an answer to a previous question. These check questions are appearing more and more in functional skills exams. I hope you find it as useful as I and my learners do.
Carefully differentiated practice in this important skill. All four operations (+, -, x, ÷) are covered. A set of 15 practical problems. An important and useful resource: so many learners lose marks by omitting checks to their work. No answer sheet. An E2-3 version is also available.
