Deforestation Causes & Scale

Understand the causes and scale of rainforest deforestation — cattle ranching (largest driver in the Amazon), soy and palm oil plantations, logging for timber, and mining — and know that approximately 10 million hectares of forest are lost globally each year, with devastating consequences for biodiversity, climate, and indigenous communities

Lesson

Set out your lesson

Explain causes and consequences while attaching forest-loss figures to a date and definition.

Before teaching

Use this short check, then start teaching.

Activity

Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Printer, credit, and teaching notes

Sequence

Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.
Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.
For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.
Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.

No Printer

Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.

Privacy

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

Amazon driver ranking, regional palm/soy comparisons and community-specific impacts are not established here. No verified current annual rate is supplied.
These bounded examples do not establish independent performance in other situations. Record the support used.

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Check understanding

Name at least three major causes of deforestation: cattle ranching, palm oil, soy, logging, and mining
State that approximately 10 million hectares of forest are lost globally each year
Explain the impact of deforestation on at least two of: biodiversity, climate, and indigenous peoples

“Can your child explain why rainforests are being cut down — naming causes like cattle farming, palm oil, and logging — and say roughly how fast it's happening?”
