- Discuss relationships between whole numbers and powers of numbers (indices).
- Students make up other numbers represented as powers.
- Students work independently answering the questions.
- Discuss answers including strategies for solving problem 8 (e.g. use the calculator to find how many thousands of millions - 5 911 + 5 911 = 11 882 - and then add zeros for millions mentally: 11 882 000 000).
- Form students into groups to prepare strategies for solving the Investigation.
- Students share strategies (in particular, ideas about scaling) and revise their plans as necessary before working on the sports area.
- Students carry out the working for their scale solar system.
- Students compare models and evaluate their success in solving the problem.
| | Reflections | Students compare models and evaluate their success in solving the problem.

2. 5 (Earth, Jupiter, Mars, Mercury, Venus) 3. Pluto, Neptune, Uranus, Saturn 4. Uranus to Neptune (1 626 000 000 km) 5. Venus (41 000 000 km) 6. Uranus 7. 5 762 000 000 km (from Earth) 8. Use the calculator to find how many thousands of millions to Pluto and back - (5 911 – 149) x 2 = 11 524 – and then add zeros for millions mentally: 11 524 000 000).
Investigation: Answers will vary but a reasonable scale might be 1 metre = 50 000 000 km
