Essential QuestionsHow would knowing
measurement affect your ability to build
something? How does measurement relate to the
solar system?
Unit Questions How do you use a ruler? What
could you use to measure objects if you did not
have a ruler? Can the area of two different
shapes be the same? Which is larger, the area or
the perimeter of a shape? If we have large
measurements, how do we scale them so we can
place them on paper?

Other fun things to do with Area and Perimeter

• Tangrams are composed of seven pieces.  One of
  the pieces is a square, another piece is a
  rhomboid, and the other five pieces are isosceles
  right triangles of various sizes. For a fun game
  with tangrams go to http//pbskids.org/cyberchase/

• Tessellation make awesome pictures with regular
  polygonal shapes http//nlvm.usu.edu/en/nav/frames
