Exploring Squares and Square Roots in Mathematics

Mr. Buffington introduces the concepts of squares and square roots. He explains squaring a number as raising it to the power of two and demonstrates this with examples. The lesson includes a visual explanation using a square to show why it's called 'squaring.' Students practice squaring numbers and learn about perfect squares. The lesson then transitions to square roots, explaining them as the opposite of squaring. Students practice finding square roots with examples, and the importance of memorizing perfect squares and their roots is emphasized.
