%Unit: Perimeter & Area% %Grade level: 10- Geometry% %Time ...

This portion of the area and perimeter unit should take five days. Topics
include perimeter and area of rectangles and squares, inputting data into the
calculator and then analyzing it.
Day 1:
Review of perimeter.
Discussion of perimeter and area, and their relation to real life situations.
Discussion of an upcoming journal entry.
Development of perimeter formula’s.
Day 2:
A Day in the computer lab with Geometer’s Sketchpad.
Developing a house layout, and then finding the perimeter and area of the house.
Day 3:
Introduction to area with geoboards.
Development of area formulas.
Day 4-5:
Flower Science, given perimeter, find all area possibilities.
Enter data into calculator, graph the data, and what do you notice?
Overall Objectives:
® Students will be able to determine the difference between area and
perimeter.
® Students will be able to use their knowledge of area and perimeter to
handle real life situations.
® Students will develop general understanding for area and perimeter
and they will see where the formulas are derived from.
® Students will use the TI-84 and its graphing functions to see relations
of area.
® The students will further their knowledge of GSP (Geometer’s Sketch
Pad) and measure area and perimeter within GSP.
® Basic introduction of Geoboards (also seen in the National Library of
Virtual Manipulatives).
