Local pinned import confirms AC9M1N01, Year 1: recognise, represent and order numbers to at least 120 with materials, numerals, number lines and charts; and AC9M1N02, Year 1: partition one- and two-digit numbers in different ways including tens and ones. |
This pack only develops 51–90 using strips and charts, with some exchange/alternate partition examples. It does not complete either description or assess the achievement standard. |

Independent desk walk-through
- Teacher: Starting after a 0–50 fortnight, the 51–90 progression has repeated ten-as-a-unit checks at 60, 70, 80 and 90. Each day has exact materials, 25 timed minutes, three original daily contexts, a response mode and a misconception response. Day 15 and 20 sheets give fresh items, while the other cards can be held for transfer. The teacher still chooses local sequence and prepares safe objects.
- Learner: I can pick a library, garden, craft, music, sport or game context without disclosing my own circumstances. The child-facing cards and checks contain no answer table. I can use the chart or tactile/large cards, and ask an adult to move objects under my control. A fully adult-built model does not count as an independently built one.
- Prospective funder/reviewer: The pair of codes, pinned workbook checksum, 30 context cards, two fresh checks, keys, original SVG/text aid and file hashes can be inspected. The claims remain narrow: two weeks, one Year 1 subject, no measured learning gain or classroom usability result. A complete Year 1 still needs Weeks 5–40 and all other learning areas, local review and testing.
Arithmetic audit: The teacher key recomputes each of the thirty card totals and every fresh check. At every ten boundary, 5 tens + 10 ones = 6 tens, 6 tens + 10 ones = 7 tens, 7 tens + 10 ones = 8 tens, and 8 tens + 10 ones = 9 tens. The amount stays constant during the exchange. The chart rows are contiguous 51–90. The workbook hash and exact code/year should be checked by the included verifier against the local pinned import. Any discrepancy stops release.

Outstanding: A Year 1 teacher must check time, progression and misconceptions with actual learners; accessibility and EAL/D reviewers should test the cards and print; each school must check local syllabus version, term calendar, safeguarding, approved technology and learner plans. No classroom outcome is implied by the mechanical checks.
