This Sports Bag assessment also includes:
Why not give surface area of cylinders a sporting chance in your classroom? A strategic problem-solving task requires pupils to consider the net of a cylinder. Individuals must determine the sizes of the pieces needed to make a sports bag, including the amount needed for the seams. They then figure out the least amount of material needed in order to cut out the pieces.
- Build the bag from the sizes given in the answer so the class can see that it actually does work
- Have a discussion on why the rectangular piece should not be 64 cm by 95 cm, using 29 cm as the diameter of the round end
- Surface area of cylinders is not directly contained in the CCSS, but pupils should be able to determine that the rectangular piece must go around the circumference of the circle
- The resource provides analyzed work that may be similar to work you see from your class
- The rubric provides suggestions on how to split the points for each portion of the answer
- The key shows how to lay out the pieces on a one-meter piece of cloth, though the answer for the question is that it would fit on 83 cm of cloth
