Here is another set of infoNotes and activities I use for a unit.
Before we begin surface area and volume, we make area apps to review area formulas. This is a fun activity and students really enjoy doing it.
I do soooooo many hands-on and application type activities during this unit. Here is a previous post where I group them all together.
Make sure you check out my surface area and volume calculator. I love using this after we explore the formulas.
