Lesson Plan:

Day 3:

Warm-up Activity: ( 5 minutes)
Look over their house plans. Make sure that everything is included rooms and units.

Discussion: (5 minutes)
Discuss today's exercise. Using GSP they will draw out there own house plan.

Exercise: (55 minutes)
Using the house plan that they drew for homework (display house plan from yesterday for an example in GSP Exercises), the student will draw out this plan on geometer’s sketchpad? The scale should be 1 cm  = 1 ft (the coordinate system is marked at 1 cm increments). Also the rooms must be labeled and dimensions clearly shown.  Calculate the area and perimeter of the rooms and the entire house.

Wrap-up: (10 minutes)
As the "ticket out the door" all calculations should be completed. The student’s should also have calculated the square footage of the entire house (area). Take the area of the house and calculate an estimated cost to build their house. (Should be given an average cost per square foot for example $75 per square foot on a 2000 square foot house would be $150,000).

Homework:
Any calculations that were not finished should be completed for homework. Also read the worksheet for the activity for next class period.
