Rounding to Decimal Places in Year 7–9 Maths

Students learn the rule: look at the next digit, and if it is less than 5 leave it, but if it is 5 or more, round up. They start by rounding to a whole number and then to one decimal place, using 6.3675 as a worked example, before applying the skill to real problems such as the cost of pizzas rounded to the nearest pound and the time on a clock. A misconception task asks whether a student has really rounded or just moved the decimal point.
