Estimating Square Roots WORKSHEET DESCRIPTION

This worksheet helps students develop confidence in estimating square roots without a calculator.

Section A introduces the concept by asking learners to identify two consecutive integers between which a given square root lies, using inequality notation. This lays the groundwork for understanding square roots numerically.

In Section B, students work with double number lines, a visual scaffold that helps them locate and estimate square roots to one decimal place, supporting learners who benefit from structured visual aids.

Section C builds on this by removing the scaffolding; here, students independently estimate square roots to one decimal place, applying their understanding in a less guided context.

Finally, Section D challenges learners with a variety of applications: completing inequalities, matching square root estimates to calculation results, and solving basic equations that require square root estimation. This section encourages deeper thinking and fluency.
