# Kindergarten - Compare Shapes

 Grade Level: K Skill: Shapes Topic: Compare Shapes Goal: Compare familiar plane and solid objects by common attributes Skill Description: Be able to differentiate between plane and solid objects. Identify attributes of flat objects and three dimensional objects. Compare and contrast objects based on their attributes.

### Sample Problems

 (1) What is the difference between a square and a rectangle? (2) Which shape has more sides, a circle or a triangle? (3) What shape is the cube made from? (4) How do you know a shape has a right angle? (5) Distinguish similar shapes by their angles (2)

### Learning Tips

 (1) Take objects from around the house to represent shapes. Ex. circle-plate ball-sphere Paper – rectangle die-cube Coaster-square Kleenex box- rectangular prism Draw other shapes that you are unable to locate. (2) Count number of side that a shape has. A circle and a sphere have no sides. Compare length of sides to one another. Ex. A square has four equal sides A rectangle has two long sides and two short sides. Count the number of corners a shape has. This is where two lines connect to make a point. (You may also mention that the inside of the corners are called angles). (3) There are some special shapes that your child should become familiar with. Trapezoid- triangle with its top point cut off. It has four sides. Parallelogram- lopsided rectangle. It has four sides. Diamond- skinny square. It has four sides. Pentagon- 5 sided shape. Hexagon- 6 sided shape. Octagon- 8 sided shape. (4) Solid objects- When two faces connect, they form an edge. Ex. A cube has six faces. Where the two faces meet is called an edge. Find edges around the house. Door frames have edges.
