# 1st Grade - Triangles, Circles And Other Shapes

 Grade Level: 1st Skill: Shapes and Geometry Topic: Triangles, Circles and Other Shapes Goal: Identify, describe, compare triangles, rectangles, squares, and circles, including the faces of three-dimensional objects. Skill Description: The student will be able to describe and compare a variety of shapes including triangles, rectangles, and circles. They will also be able to describe the faces of three dimensional objects.

### Sample Problems

 (1) Describe a circle. (round, continuous) (2) Describe a square. (four straight sides that are all the same sides) (3) Describe a rectangle. (four straight sides. Two sides are smaller than the other two sides.) (4) Describe a triangle. (three straight sides, three points) (5) What is the difference between plane and 3 dimensional shapes. (Plane shapes are flat. Three dimensional shapes are solid and have more than one surface.)
