We will explain how to find the area of rectangles using the TI 84 tutorial. We will use “Area Explorer” from Project Interactivate to demonstrate how to find the area of different rectangular shapes. A Pre-designed house plan from GSP will be given to the students (to be loaded in each computer) to simulate a floor renewal. Students will calculate different areas from the house floor plan and collect the data.
