Readings

Area
~Area is defined as the amount of space covered by the inside boundries of a two demensional figure and the formula is A=LXW

~Finding the area of irregular shapes
~Creative ways to come up with answers
~Explore own ways to find area of irregular shapes on grid paper (come up with their own strategies). Then share in pair share or classroom discussion, or they could write in their math journals as writing across the curriculum.

~Might be beneficial to discuss what units of measure are used in area. To piggy back that idea, what does a squared centimeter look like, etc. Then they could explore areas and their appropriate units of measure (EX. Not going to measure a soccer field in squared inches)

~Trace their hand on grid paper then find the area of their hand.

~In everything that they are doing they should reflect in their math journals

Which Measure is It
~Can two shapes have same area but different perimeters? Explain?

~To show understanding students need to construct visual representations of figures, generate word problemss, and justify properties.
