KS3 Rounding Off Numbers in different currencies

Rounding off numbers is an important part of Maths and a very handy tool for everyday life. To introduce rounding off numbers to my pupils, I do an activity on the board using the numberline. This helps them to see it visually. It works for the many who do not understand why we round up for 5 and greater and round down for less than 5. It gets them in the habit of estimating amounts of money, lengths of time, distances, decimals and many other physical quantities. We practice a lot and mastered it comprehensively. As a result, this worksheet takes a little of their time.
