Reflection: Discourse and Questioning Volume of Prisms - How are base area and volume of a prism related? - Section 2: Explore


I found it really helpful to have students write down the name of the figure and the shape of its base. Naming the base really helped the kids identify the correct formula for finding the area of the base.  Also, I really emphasized calculating the area of the correct base - in triangular prism you can multiply length, width and height and divide by 2 - but that steers away from the idea of volume being the area of the base times the height.

Volume of Prisms - How are base area and volume of a prism related?

Unit 8: Geometric Measurement
Lesson 8 of 18

Objective: Students will be able to calculate the volume of rectangular and triangular prisms.

Big Idea: Volume is related to area – what?! Students get to make connections to volume through the idea of “stacked” area.
