Realising that this provocative math prop would not last long on the floor of my classroom, we elected to suspend it from the ceiling instead.
(Critical tip for those thinking of following suit: Use LOTS of tape to make sure the thing doesn't fall down overnight and set off the school's alarm. No, seriously!)
My coach was right, btw: I did need a cubic metre hanging from my classroom ceiling: It's been all the rage, and our unit launch for measurement was a success as students worked in groups to ponder what in the world might take up a cubic meter of space, and refreshing their vocabulary memory describing this paper beast with whiteboard markers on their desks (comes off with a damp cloth)...
- Find the surface area of a variety of 3-D prisms.
- Determine the volume and capacity of a variety of 3-D prisms.
- Use measurement concepts to solve problems and make mathematical decisions.
- Use written and verbal communication effectively to justify their mathematical problem solving.
- Use technology/manipulatives to solve problems and justify solutions.
Success Criteria - Grade 8:
- Use formulae and mathematical notation to determine the volume of a cylinder
- Determine and use the relationships among units (cubic cm to mL, cubic cm to cubic m) in order to solve problems related to capacity
- Apply knowledge of volume and capacity to communicate understanding of real-world circumstances
