| MTS Set | MTS7

| NATIONAL Curriculum | The Number System |
| Topics | Understand Whole Numbers
|
| Keywords | Volume, Strategies, Large Numbers, Integers |
| Grouping | Learning pairs |
| Resources | Have available: 1 cm cubes, metre tapes or rulers, calculators |
| Lesson Notes | - Allow students time and space in their learning pairs to develop strategies and commence working (measures etc) before interacting with them.
- Come together as a class when most learning pairs appear to have initiated a strategy for the first problem. Share ideas and encourage students to question each other.
- Allow students the opportunity to reassess their strategy and working as necessary.
- Repeat for Investigation 2.
- Discuss: How many cubic centimetres in 2 m3? 3? 4? 10? ... Is a cubic metre always the same shape? How many shapes can we make that are a cubic metre?
- Note: The term cubic metre is a little confusing as it refers to the amount (volume) of space taken up and not the shape (cube). That is, any space equivalent to 1 m x 1 m x 1 m, regardless of its shape, is referred to as a cubic metre.
- Extend: Investigate measurement of difficult volumes such as the volume of spheres.

| Reflections | Ask: Did you go back and change your plan while you were working? How did you know you had answered the question? Did you work well as a team? Give me an example of how you did (or did not) work well as a team?...

| Answers | Investigation 1. 1 cubic metre = 1 000 000 cubic centimetres
Investigation 2. A cubic metre can be represented by any shape where the length x width x height = 1 000 000 cm3
e.g. 10 cm x 100 cm x 1000 cm, 500 cm x 200 cm x 10 cm...
