5. Lesson Vocabulary Prism A solid object that has two identical ends and all flat sides. The cross section is the same all along its length. The shape of the ends give the prism a name Right, Rectangular Prism A solid (3-dimensional) object which has six faces that are rectangles. Volume The amount of 3-dimensional space an object occupies. Capacity.
6. Warm Up/Do Now OBJECTIVE: SWBAT develop and utilize the formula for the volume of right, rectangular prisms. Explain why the figure at left happens to be called a Right, Rectangular Prism. Think of 3 examples of these prisms that you encounter in everyday life. What geometric term do we use to describe the space inside 3-dimensional figures? Why is such space measured in cubic units rather than square units like when measuring Area? Agenda
7. Agenda OBJECTIVE: SWBAT develop and utilize the formula for the volume of right, rectangular prisms. 1) Warm Up: Independent (10 Min) 2) Launch: Teacher Guided Problem (15 Min) 3) Explore: Partner/Group Investigation (30 Min) 4) Summary: Independent (5 Min) 5) Practice: Homework
8. Problem Launch Jamal started a Boston business, City Crave, selling chocolate bars made using his grandmother’s recipe. He wants to ship the bars to a candy store in Los Angeles. City Crave Agenda
9. Jamal has 3 shipping box options. What are some important things for Jamal to consider? No vertical stacking or bars will break. Tall Wide Cube First, he needs to know how much space is inside each box ! Agenda
10. Measuring Area Vs. Measuring Volume Remember that when we wanted to find the space inside a 2-dimensional, flat shape, we determined how many 1 x 1 squares fit into that shape. Area of rectangle is 18 units2 3 units 6 units Well, to find the space inside of Jamal’s boxes (3-dimensional prisms), we will use 1 x 1 x 1 cubes instead of flat squares. Don’t worry yet about the fact that his candy bars are not cubes…focus on box space. Agenda
11. 1 X 1 X 1 cube How many cubes will fill each box ? (these boxes are on CW page #1) Agenda

15. Summary, Key to Leave, HW 3) Calculate the volume of the prism. Show all work. Measured in cm. Provide a definition for volume. How is it different than area and perimeter? (think units) What is the formula for the volume of Right, Rectangular Prisms? Challenge - Given a right, rectangular prism with a volume of 120 cm3, length of 12 cm, and width of 5 cm, determine the prism's height. Agenda Name:
