Estimating Powers and Roots WORKSHEET

Suitable for Year groups: Year 7, Year 8
GCSE Tier: Foundation
Targeting grades: 1-3
Prerequisite knowledge: Square and cube numbers.
Learning Objective: Estimating powers and roots

Estimating Powers and Roots WORKSHEET DESCRIPTION

This worksheet is perfect for helping learners with their understanding of powers and roots, and also strengthens the important skill of estimation.

Section A starts the worksheet by providing some number lines to help learners think what whole number values some square roots would lie between.

Section B then asks learners to complete a table about cubes and cube roots.

Section C then requires learners to think about sensible intervals for answers to square and cube roots.

Section D has a short matching exercise and the worksheet finishes with an extension question asking learners to estimate the answer to an equation.

All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions

Students should have a solid understanding of square and cube numbers before tackling this estimation work. This foundation is essential because the worksheet builds upon recognising perfect squares and cubes to help learners identify reasonable intervals for non-perfect roots. Without this prerequisite knowledge, students may struggle with the number line activities and interval estimation tasks.
