Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Types of rocks means naming rock types (igneous, sedimentary, metamorphic) and process words like weathering, erosion, and deposition. We will practise once together, then check a fresh example.
Spend about 12 minutes matching three rock-type words and one process word, then checking a fresh term.

Check understanding
- Correctly classify igneous, sedimentary, and metamorphic rocks and explain in one sentence how each type forms
- Use 'erosion', 'weathering', and 'deposition' correctly as three distinct stages in a sequence
- Explain how fossils form using 'sediment' and 'sedimentary rock' correctly
“Could your child explain the difference between a rock being weathered and being eroded — those are actually two different things?”
