Every Level 2 paper has at least one ‘estimate’ question and several where the mark depends on rounding sensibly – to the nearest penny, to a whole number of boxes, to one decimal place. This free worksheet covers decimal places, significant figures, estimating by rounding to one significant figure, and deciding what rounding a real situation needs.

Free to download, print and share for personal or classroom use. Answers included.

Common mistakes on this topic
From our tutors’ marking and the most recent examiner reports – check your work against these:
- Estimating with exact numbers – the mark is for rounding to 1 s.f. before calculating and showing it.
- Rounding too early in a multi-step calculation. Keep full accuracy until the final answer.
- Rounding 0.03974 to 2 s.f. as 0.04 rather than 0.040 – both digits must be shown when asked for 2 s.f.
How to use it
- Print the worksheet (or work on screen) and attempt every question without looking at the answers. Give yourself a rough time limit – Level 2 exams are tight.
- Mark your work against the answer page. For maths, check the method as well as the final number; method marks are where most of the marks are.
- Read the ‘common mistakes’ notes below and check whether any of them happened to you. Then redo the questions you got wrong a day later.

Frequently asked questions
What is the difference between decimal places and significant figures?
Decimal places count digits after the decimal point. Significant figures count from the first non-zero digit wherever it is. 0.03974 to 2 decimal places is 0.04; to 2 significant figures it is 0.040.
How do I estimate an answer in the Functional Skills exam?
Round every number in the calculation to one significant figure, write those rounded numbers down, and calculate. 38.7 × 21.2 becomes 40 × 20 = 800. The mark is for the rounding and the method, not for being close.
When should I round up in a Functional Skills question?
When the answer is a number of things you need enough of – packs, tins, coaches, staff. When the answer is a number of complete things you can make, round down. Money is rounded to the nearest penny unless told otherwise.
