Square Roots Approximating (Level 3)

This math topic focuses on approximating square roots, specifically embedded within a unit on "Squares and Square Roots - Advanced". The learner is asked to find the best approximate value of square roots for several numbers (e.g., 150, 151, 152, etc.) with multiple choice answers provided for each problem. Each question allows learners to practice and strengthen their skills in estimating and finding near-accurate values of square roots for non-perfect squares.
