Applied Knowledge Assessment: Nets in the Kitchen
Part 1: Nets
Recall (refer to page 12 in your textbook if necessary) that a net is a two-dimensional pattern that you can fold to form a three-dimensional figure. You are to create nets for two different boxes from your house. Some good box examples include: cereal boxes, pasta boxes, cracker boxes, etc.
1. Rummage through your house and locate the two different boxes that you will use for this activity.
2. In the space provided below, describe what your original box looks like in a few sentences. You may also take pictures of your box and insert them into this document; however, this is not mandatory. When describing each three-dimensional figure, be sure to use complete sentences and proper grammar/spelling.
3. Create a net for each box. You may cut the box to help you unfold it into a two-dimensional piece.
4. Sketch your net in the space provided below. You must sketch your net by hand. The size of the net will not be drawn to scale. Draw each net to fit in the provided space. Use a ruler or other straight edge to make neat, straight lines.
Part 2: Perimeter and Area
Part 2 of this assessment will focus on perimeter and area. Choose one of your boxes from Part 1 to complete this activity. You will need a ruler.
1. Measure the top of your box. Draw a picture of the top of the box. Include your measurements and label the units. You may use inches or centimeters for the units. (Be sure to use the same units for the remainder of Part 2.)
2. What is the perimeter and area of the top of the box? Show all work and include the proper units.
3. Measure the front of your box. Draw a picture of the front of the box. Include your measurements and label the units.
4. What is the perimeter and area of the front of the box? Show all work and include the proper units.
5. Measure the bottom of the box. Draw a picture of the bottom of the box. Include your measurements and label the units.
6. What is the perimeter and area of the bottom of the box? Show all work and include the proper units.
7. Compare the areas of the pieces of the box. Which pieces have the same area? Why?
8. There are some pieces of the box that we did not measure. Use your knowledge of area and your findings from the previous questions to infer which pieces of the box will have the same area (you do not need to calculate the actual areas here). Be sure to list all parts of the box (top, bottom, front, back, side 1, and side 2).
