Unit 5, Lesson 2

Find and name two-dimensional shapes including trapezoid, rhombus, and a square as special rectangle, based on defining attributes of sides and corners.

In this lesson, students connect defining attributes of shapes to the names of those shapes. Along with circle, triangle, rectangle, and hexagon (introduced in Kindergarten), students learn trapezoid and rhombus. From Kindergarten, students recall squares as special rectangles.
