8th grade · Expressions & Equations
Use square root and cube root symbols to represent solutions to equations of the form *x*^2 = *p* and *x*^3 = p, where *p* is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
2 interactive, auto-graded activities for 8th grade students practising 8.EE.A.2. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Explore how squaring and square roots are inverse operations through an interactive slider and table. Students calculate squares, find corresponding roots, and estimate roots of non-perfect squares — discovering how rational and irrational numbers emerge through hands-on exploration.
Help students master square roots and cube roots with real-world problems involving areas of squares and volumes of cubes. Learners solve equations like x² = p and x³ = p to find missing dimensions. Supports randomization so each student receives unique problems and answers.
