Reply To: Lesson 3 – Teaching Through Task – Discussion

[Kyle Ferreira van Leer]

I do a lesson on what happens to the surface area and volume of rectangular prisms when you scale up their dimensions (from Jo Boaler’s Mindset Mathematics Grade 7). I would love to see students going through the comparison stages with the nets or even just images of the prisms for an example or two. They can begin by looking visually, then they can use unit blocks to compare them, and finally they can move towards measuring them with rulers and we will be able to eventually understand surface area and volume with a simple image with abstract measurements.
