Square Roots Approximating Between Perfect Square Roots

Level 3

This math topic focuses on approximating square roots between perfect square roots at an advanced level. It involves identifying the closest perfect square roots that are just smaller and larger than the square root of a non-perfect-square number. Learners practice pinpointing these boundaries by considering numbers like 87, 72, 28, 137, 107, 156, and 154, determining the perfect squares that lie immediately below and above their square roots. The exercises enhance understanding of squares and square roots, refining estimation skills and familiarity with square number properties.
