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? _______________________________________________ Channel-talkmeasurement mailing list Channel-talkmeasurement@learner.org http://www.learner.org/mailman/listinfo/channel-talkmeasurement You may un-subscribe from this email list at any time by using the online form at the above URL.
