|Introduction | Finding the Area of Different Figures | Try It Yourself: Finding the Area of Dot-Paper Shapes | Summary | Your Journal|
To find the area of a figure, we need to determine the number of square units that make up that figure. For example:
Think about what you just did with the parallelogram. Describe with pictures and words the answers to the following questions. Remember, the focus here is on communication, so your answers need to clearly communicate your thinking and the process you used to solve the problem.
1. What makes finding the area of a parallelogram more difficult than finding the area of a rectangle?
2. Explain how you found the area of the parallelogram. How did you deal with the parts of square units that were "hanging off the edge"?
3. What would be another way to count the total area? Explain your new method in words and with a drawing.
