Thanks for your response. My school district just adopted the
Investigations series. We are using MathThematics at the middle school
level.

Third grade unit - Exploring Solids and Boxes from "Investigations in
Number, Data and Space" provides opportunities for students to explore
surface area and/or volume. Investigation 3: Making Boxes, and
Investigation 4: How Many Cubes in a Box?

Subject: [Channel-talkmeasurement] Surface Area & Volume
Some of my middle school students have trouble keeping surface area and
volume straight. Earlier this year, my students were assigned a problem
in which they were supposed to determine the number of unit cubes in a 3
x 3 x 3 cube. They were given a drawing and could make and use models
to help them solve the problem. Most of the students came up with 27
cubes, but some had an answer of 54 cubes, even after making and using a
model. (54 sq. units is the surface area, not the volume.) At what age
should students have experiences with surface area? If you teach
elementary school, do your students have opportunities to explore
surface area and/or volume? Do you have any tips on how to help
students with these two measurement concepts?
