Grade: 2 pts. for Padlet post.

Step 2: Make a model (3 pts)

Draw a picture that will help you solve the problem. Make sure you include all of the possible rectangles in the problem, not just the one you think is the correct answer. When your drawing is ready, take a screen shot or photo of it and post it to this Padlet.

Make sure you look at the ways in which your classmates have represented the problem. Then come back and finish the lesson when you are done.
