4) Bring class together. Review strategies / solving of 2-70 a – f.

4b. SWBAT:Calculate the perimeter and area of regular and irregular shapes using a variety of methods.

Perimeter:

The total distance around the outside of a 2-dimensional shape. You calculate it by adding together lengths of all the sides of a shape.
