Watch how we find which perfect squares a non-perfect square root falls between — and how to decide which it’s closest to.

You’ll see step-by-step how to:
✅ Identify the two nearest perfect squares
✅ Place the irrational square root on a number line
✅ Estimate its approximate value
✅ Apply this skill to common examples like √12, √18, and √50

This lesson supports Common Core Standard 8.NS.A.2, helping students understand how to approximate irrational numbers and compare their values.

Perfect for 8th-grade math students, teachers, and parents looking for quick concept reviews!\n
