Volume

| 0 comments

Activity 1 (individually): 

  • Pretend to be an architect. Design as many buildings as you can, only using six 1 cm³ blocks (MAB blocks).
  • “Can you make one that takes up a bigger space than another”
  • “Can you make one that takes up a bigger space than others at your table?”
  • Take a walk around the room. “Who’s building takes up more space?”
  • Is a building 6 blocks high the same as a building 6 blocks long? What is similar and different about the buildings you have made?

Question (turn and talk): Which shape below takes up more space? Justify answer.

Definition: Volume is the amount of space a 3D object takes up.

 

Activity 2 (with a partner): 

  • Pretend to be an architect. Using ten 1 cm³ blocks (MAB blocks) design a building. Then one with 20 blocks, then one with 30 blocks. As you build each one compare it to others on your table.
  • Pick a simple rectangular object on your table, make a full scale copy of it with MAB. Compare it to other made at your table. Which has more volume (takes up more space)?

Activity 3 (whole class): 

Activity 4 (with a partner): http://www.interactivestuff.org/sums4fun/3dboxes.html  (use real MAB to build what you see on screen if that helps you count how many are there)

Extension activities information (this is not required at your year level, but you can record it if you want)

How it is measured: Volume is measured in cubic units. For example a cubic cm block takes up 1 cubic cm. This is written as 1 cm³. Bigger objects may be measured in bigger units such as cubic meters, or m³

Pronounced: centimetres cubed or meters cubed.

The Formula: Volume = length x width x height.
