Year 11 / Mathematics / Term 1 / Weeks 03 04

Part of the full two-week lesson sequence. Check the pack guide and taught point before teaching.

Open for this lesson: Pack guide · Fresh learner checks · Aids and text routes.

Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.

Learner choices

Goal: transfer GST-base and simple-interest reasoning to new independent values. 25 = 2 + 3 + 12 + 5 + 3.

0–2: Explain the new case is public practice and its tax and interest assumptions are stipulated; it is not a QCAA exam or real advice.
2–5: Offer exact reading, large text, calculator, tactile factor cards, AAC/sign or exact-word scribe without giving the method for these new values.
5–17: Learners show first independent reasoning; collect before content feedback.
17–22: After collection, revisit exclusive or inclusive base? / annual rate and years? / model or reality? Routes: price blocks; annotated equation table; spoken/typed two-case audit. Preserve first evidence and record any hint.
22–25: Use the public worked key to choose a specific next practice. Move: create a new local parallel check when prior access made the first response ambiguous.

Alternative domain: Fictional sports-poster supply and a completely invented interest table after assessment. Optional/home: explain the difference between a percentage on a base and an included total.
