GCSE & iGCSE Rounding & Estimation worksheet

Rounding and estimation worksheet for GCSE and iGCSE maths: significant figures, truncation and estimating. Foundation and Higher, with full solutions.

A complete rounding and estimation worksheet for Pearson Edexcel GCSE (1MA1) and International GCSE (4MA1), written so one resource works for both tiers. Every section is clearly labelled Foundation or Higher, and questions get harder as you go.

What’s covered — Foundation

Rounding to decimal places and significant figures, and truncating
Estimating calculations by rounding to 1 significant figure
Using estimates to check answers

What’s covered — Higher (grades 6 to 9)

Deciding whether an estimate is an over- or underestimate
Estimating roots of any number
Estimating with formulae

How it’s structured

A. Worked examples & Your turn — a model solution beside a matching question to try
B. Fluency — core skills
C. Reasoning — explain it
D. Problem solving — unfamiliar, multi-step questions
E. Exam practice — exam-style questions with mark allocations

122 marks across Sections B to E (61 Foundation, 61 Higher), with a progress tracker on the front page so students can record their score per section. The over- and underestimate questions require a written justification, which is exactly where students lose the final mark on the exam.

How to use it

Works as a full lesson, homework, a cover lesson or targeted intervention. Because each tier is labelled, you can set the Foundation sections to one group and the Higher sections to another from the same print.
