## Reflection: Developing a Conceptual Understanding Unit Cubes and Volume - Section 2: How many cubes will it take to fill up the box?

As I walked around, I saw many students working to figure out how many blocks they would need to fill the bottom (here and here).  Next, I saw most students using the unit blocks to figure out how many layers it would take to fill the box up to the top.  When I asked one group how many blocks it would take to fill the box, they told me the amount of blocks for only one layer.  I then told the group that that amount would fill part of the box, but part of the box would still be empty.  I explained again that they need to fill the box completely up to the top.  A minute later, they were able to tell me the correct amount of blocks.  Being able to work with the blocks and boxes helped students visualize finding volume as filling a box with layers and help students connect to the volume formulas including,  Volume= Area of the base times the height.

Developing a Conceptual Understanding: Working with Unit Cubes

# Unit Cubes and Volume

Unit 8: Geometry
Lesson 12 of 19

## Big Idea: What is volume? How many unit cubes would it take to fill this box? Students work to develop formulas for finding the area of rectangular prisms and cubes.
