Topic # 6 Analyzing Shapes

Learning Expectations:

* Compare and contrast the attributes of 2- and 3- dimensional shapes.

* Use a square corner (An angle that measures 90 degrees. Also called a right angle)

* Draw lines of symmetry. (A line dividing a two- dimensional figure into two parts that are mirror images of each other. Also called balance line.)

In this topic we will use clues to describe shapes. Here is a sample of “clues” that we will use to help us talk about shapes:

* the shape is a parallelogram * It has more than one line of symmetry

* the shape is a polygon * the opposite sides are the same length

* the perimeter is 32 cm * the shape is a quadrilateral

Sample problems:

Draw a polygon. (A polygon is a plane shape or figure bounded by straight sides.)

(A circle or an oval are not polygons.)

Draw a rectangle. Write as many facts or clues about the shape.

For example: The shape has more than one right angle.
