Use these formulas to find the areas of more complex figures by dividing the figures into basic shapes. Make a list of small things. Compare things on the list to other things which are smaller or larger than those listed. One student stands up against a large piece of butcher paper tacked to the wall. A silhouette of his body is traced.
Students compare the child's silhouette to that of an adult's tacked up next to the child's.
Using non-standard and customary measurements, a comparison is made of the two silhouettes. Results are recorded on a T-Chart. Discuss the relative scale of doors to an adult and then to a child. Stress the idea that a door must be tall enough to walk through. Teacher explains that students are to draw people in the pictures who would be able to go through the doors of the building.
