I think this will help my grade 8s with many of their units, especially in surface area. I always feel that I should be able to get to the formulas because of prior knowledge but I always find so many students are unable to manipulate the forms to unfold them to figure out where the measurements go.I think this year I will slow it down and go back a little bit so we can build that understanding.
direct comparison-comparing two rectangular prisms and deciding which one might have the largest surface based on a visual inspection
indirect comparison-use square tiles to cover the different face to determine the areas
direct measure-unfold the prism to be a 2-D net and use tiles to measure every face of the net and build a connection to measuring with a ruler
indirect measure-using the formula to determine surface area
We will be able to repeat this process with triangular prisms and cylinder. As we move into volume a similar process can be used.
