In the age of calculators, basic number facts sometimes get lost. Use this note sheet and quick quiz as an activator to keep skills fresh or as teaching tool for those first learning perfect squares. -Note sheet explains the concept of the perfect square verbally, visually, and in multiple numeric representations. -Timed quiz sheet gives students space to complete perfect squares 0-12, 15, 20, and 25. Tip: I love to use this right before my students learn about square roots.
