OBJECTIVES

• Build geometric figures with other common shapes
• Name concrete objects and pictures of
  three-dimensional solids
• Describe relationships between two-dimensional
  and three-dimensional objects

SHAPES WHAT ARE THEY?

• Square  A 4 sided shape that has four right
  angles and four equal sides.
• Rectangle A 4 sided shape that has four right
  angles and parallel sides are equal.
• Triangle A polygon with three sides.
• Circle The set of all points in a plane that are
  the same distance, called the radius, from a
  given point, called the center.

Build geometric figures with other common shapes

• To make different shapes you can use triangles,
  square and parallelograms to make different and
  better objects is called TANGRAMS
• A fun way to see how to make some fantastic
  figures with basic shapes Tangram Activity

SHAPES
in 3-D

• Two Dimensional shape that has height and width
  (flat on paper)
• Three Dimensional object that has height, width
  and depth (something you can hold)
• Construct 3-D objects
• Guess the 3-D objects

7
2 Dimensional Vs. 3 Dimensional

• flat
• sides
• angles
• Compare 2-D shapes
• find the ATTRIBUTES

• able to hold
• sides
• angles
• faces
• edges
• vertices
• base

WHICH ONE IS BETTER??

TURN, ROTATE, SLIDEMAKE UP YOUR MIND!
Slide moves from left to right
Flip movement of a figure to a new position by
flipping the figure over
Rotation - A movement of a figure by turning it
around a fixed point.
9
Symmetry
When one half of a figure looks like the mirror
image of the other half.
