11. END OF LESSON The next slides are student copies of the notes for this lesson. These notes were handed out in class and filled-in as the lesson progressed. NOTE: The last slide(s) in any lesson slideshow (entitled “Practice Work”) represent the homework assigned for that day.

12. Rectangular Prism Net Directions: Cut flattened shape out. DO NOT cut along the inside lines. Once cut out, fold along the inside lines to make a rectangular prism (or box).

13. Cylinder Net Directions: Cut flattened shape out. DO NOT separate the top and bottom circles from the rectangle. In other words, you should end up with ONE CUT-OUT shape– NOT three separate ones!! See if you can form a cylinder! 13 cm. 13 cm 6 cm 2.5 cm
