This Instructional Activity is a part of the Lesson 3, Unit 8, Grade 8. In this activity, students draw three squares on small grids, building on their earlier work. Two of the three possible squares have easily countable side lengths since they line up along the grid lines. The third likely possibility, that of a tilted square with vertices at the midpoint of each side of the grid, has sides equal to the length of a diagonal of a 1 unit square.
