These are partial teaching opportunities across ten 25-minute lessons. They do not mean a content description or achievement standard is fully met, a term order is mandated, or every state/territory uses the same reporting schedule.

| Official code | Workbook row | Level | Exact official content description | Taught opportunity and limit |
|---|---|---|---|---|
| AC9M5N06 | 17704 | Year 5 | solve problems involving multiplication of larger numbers by one- or two-digit numbers, choosing efficient calculation strategies and using digital tools where appropriate; check the reasonableness of answers | Days 11–17 and 19–20 multiply larger numbers by one/two digits, compare strategies and reasonableness; limited 2-week number set. |
| AC9M5N08 | 17713 | Year 5 | check and explain the reasonableness of solutions to problems including financial contexts using estimation strategies appropriate to the context | Days 11, 14–17 and 19–20 use prior estimates and bounds including fictional costs; some decisions still need exact totals. |
| AC9M5N09 | 17717 | Year 5 | use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate the problems, choosing operations and efficient calculation strategies, using digital tools where appropriate; interpret and communicate solutions in terms of the situation | Days 16 and 19–20 formulate fictional product/limit decisions and state unknown information; no full modelling range. |
| AC9M5A01 | 17727 | Year 5 | recognise and explain the connection between multiplication and division as inverse operations and use this to develop families of number facts | Days 17–18 and 20 use a product/inverse family to check group relationships; division strategies need later practice. |
| AC9M5A02 | 17732 | Year 5 | find unknown values in numerical equations involving multiplication and division using the properties of numbers and operations | Day 18 solves three multiplication equations with an unknown and substitution; one-day sample only. |
