|Stage 1- Desired Results |

|Established Goals: (TEKs) |

|Geometry |

|(10) Two-dimensional and three-dimensional figures. The student uses the process skills to recognize characteristics and dimensional changes |

|b. determine and describe how changes in the linear dimensions of a shape affect its perimeter, area, surface area, or volume, including |

|proportional and non-proportional dimensional change. |

|(11) Two-dimensional and three-dimensional figures. The student uses the process skills in the application of formulas to determine measures |

|of two- and three-dimensional figures. The student is expected to: |

|d. apply the formulas for the volume of three-dimensional figures, including prisms, pyramids, cones, cylinders, spheres, and composite |

| |Given information of a cylinder (i.e. dimensions or volume, students |

|Lesson Summary |

|In this lesson, students will discover and use different volume formulas and make predictions based on observations or conjectures. This |

|lesson uses two 3D shapes (prisms and cylinders) and discusses the difference in volume each produces using the same size paper to form each |

|shape (i.e. same surface area). |

| |

|Objectives |

|Students will be able to determine the volume of rectangular/square prisms and cylinders using information such as the height, radius, |

|circumference, etc. Students will also discover how changes in these pieces of information impacts the volume. |

|(10) Two-dimensional and three-dimensional figures. The student uses the process skills to recognize characteristics and dimensional changes |

| |

|Duration |

|This lesson should take about 1 to 2 hours, so plan for at least 2 classes. |

| |

|Lesson Type |

| |

|Group activity (3-4 students per group) |

| |

| |

|Technology Integration |

|After the lesson, the students will explore more ways how each dimension of a 3D shape will impact the volume. This website provides an |

|interactive program that allows you to adjust the dimensions of each shape and compare two individual shapes simultaneously. |

|Instructional Procedures |

| |

|Students should work in pairs because they will work together to create the objects and in filling the objects with popcorn. Pass out the |

|Popcorn Prisms Anyone? activity sheet, a piece of white paper, a piece of colored paper, tape, and a ruler to each pair of students. It is |

|helpful to spend time showing students some model rectangular prisms, reviewing the volume formula, demonstrating the prism construction. |

|Popcorn should not be used for the demonstration, but students should be able to see how the prisms fit inside of each other. |

|Circulate around the room as students work through the activity sheet. After students finish Question 2, hand each group a bowl of popcorn and|

|a cup for transferring the popcorn. Suggest to students that one hold the rectangular prism as the other fills the tall prism without spilling|

|the popcorn into the shorter one. If availability allows, watch students during this part of the activity to see their reactions. |

|Question 6 may be difficult for some students. You may choose to guide students by asking them the dimensions of their rectangular prisms. |

|After students conclude that the bases are squares, ask for the formula for finding the area of a square. Students should be able to transfer |

|this knowledge to the volume formula. Ask more advanced students how to relate the side of the rectangular prism to the side of the |

|rectangular piece of paper use to form the prism and create a formula for volume based on this. They should find: |

|V = (w/4)2 · l |

|where l and w are the length and width, respectively, of the original rectangular paper |

|Question 7 can be used as enrichment for students who finish early. Have tactile learners use their original rectangular prisms to determine |

|the length and width by changing the dimension. Encourage students to play with the numbers and explain their methods for solving the problem.|

|At the conclusion of the activity, model the algebraic solution if no students found one. |

|The beginning of the cylinder activity should closely mimic the prism activity. Distribute the same materials and the Popcorn Cylinders |

|Anyone? activity sheet. Again, model the cylinders and have students follow the same steps as in the rectangular prism activity. Show students|

|how to measure the diameter, stressing it is only an estimate, and the lesson should run smoothly. |

|Students may struggle with Question 6. Direct them back to the prisms activity. The example in Question 6 is very important for helping |

|students see concrete examples before tackling the remaining questions. If they copy the answer from the prism activity, ask them why they can|

|substitute radius for side-squared. Once most groups have completed the activity, you should write the following formulas on the board: |

|V = πr2h |

|V = w2h  |

|Provide initial values for the radius and the height and ask students how the volume changes as you increase each by one unit. Duplicate the |

|activity for the volume of a square prism. This is a good place to reinforce what the patterns implied with the activities. For enrichment, |

|provide models of square prisms and ask students to compute the change in volume as the sides and height are increased. |

|If time allows, the Comparing Cylinders activity sheet is available to help students understand the concept of calculating radius given |

|circumference and that the circumference of the popcorn cylinder was formed from the side of the rectangular paper. Have materials available |

|for students who want to recreate the cylinders. |

|It is suggested that Questions 1–9 be instructor-led with student input. Select students in different groups to help with the answers and |

|question the students as they build the cylinders. The student pairs should be able to complete Questions 10 and 11 based on the prior |

|questions. |

|To bring closure to this activity, a class discussion of the results is important. Questions for Students can be posted on the board and |

|groups walk around and add their comments for the class discussion. During the discussion, encourage both concrete examples and algebraic |

|reasoning. |
