Activity 2
Activity 3
Your teacher will give you either a Problem Card or a Data Card. Do not show or read your card to your partner.
Information Gap routine. Step 1, both students read the problem card. Cycle. Problem card student says, can you tell me, fill in the blank? Data card student says, why do you need to know, fill in the blank? Problem card student says, I need to know, fill in the blank, because dot, dot, dot. Data card student listens to partner's reason and answers with information from the data cards. Repeat cycle until the problem card student can state, I have enough information to solve this problem. Both solve the problem independently and continue to ask questions if more information is needed. Finally, share data card, then compare strategies and solutions.
Pause here so your teacher can review your work. Ask your teacher for a new set of cards and repeat the activity, trading roles with your partner.
Student Section Summary
We learned to find the volume of a right rectangular prism by multiplying the side lengths or by multiplying the area of the base by the height.
Each of these expressions represents the volume of this prism. The volume of this rectangular prism is 60 cubic units.
We learned to use different cubic units to measure the volume of objects of different sizes. We used cubic inches, cubic feet, cubic yards, and cubic centimeters to measure volume.
