I use this activity to introduce my students to the concept of square roots. It starts by having students draw as many squares as they can on grid paper. Students are then asked to analyze the squares to see how long their sides are and what their area is (in squares). Once students have that data, they are able to make connections between the length of side and the area (side x side = area). This enables a discussion about square roots and perfect squares, as the students will have essentially drawn the first several perfect squares. I talk with them about what a root is, and we go over how the length of the side is like a root of the square. This also allows me to introduce the idea that raising a number to the power of 2 is also called "squaring" a number. The last sheet in this download is a practice sheet for students to practice identifying perfect squares and square roots.
