What the Learning Will Be:

Lesson Objective: 

Subject Matter and Grade Level:  

Third Grade, Mathematics

Where You Will Go to Learn It:

Web Resources:

• Virtual Geoboard
Introductory investigations into the concept of area

• Shape Surveyor
Three games using perimeter and area

• Interactive Geoboard
Another virtual geoboard on which to create rectangles of different dimensions

What You Will Do to Learn It:

Research Activities

1. On the Virtual Geoboard choose the activity "Coloring Squares and Triangles".
   
2. On the Virtual Geoboard choose the activity "Putting Squares in Rectangles".

1. On the Interactive Geoboard, pick "Grid Selection #2", and create 6 different sized rectangles.
2. On the Interactive Geoboard, delete 4 of your rectangles by clicking on the colored toggle buttons.
3. On the Interactive Geoboard, can you create 2 rectangles that have the same number of squares, but have sides of different lengths?

1. On the Shape Surveyor, play "Perimeters" (on "Easy").
2. On the Shape Surveyor, play "Area" (on "Easy").
3. On the Shape Surveyor, play "Area and Perimeter" (on "Easy").

1. ESSENTIAL QUESTION:  If two rectangles have the same area, are their perimeters always the same?
2. Can you prove your answer with a drawing on one a real geoboard?
3. Can you prove your answer with a drawing you do on a piece of graph paper?
