Use after the learner's first response. Keep this page out of the learner stack. The 900 limit is a rule of an invented paper-card model. None of these outputs establishes a real visitor preference, price, safety, accessibility certification or event approval. Record independent reading separately from listened comprehension; record whether multiplication, plan choice or wording was prompted. A child may use AAC, pointing or a scribe without losing their mathematical agency when the child selects the steps and explanation.
| Plan | Exact product | Comparison with 900 | Useful check |
|---|---|---|---|
| Book swap | 46×18 = 828 cards | Fits; 72 below limit | 46×(20−2) = 920−92 = 828. |
| Games meet | 24×37 = 888 cards | Fits; 12 below limit | 25×37−37 = 925−37 = 888; 888÷24 = 37. |
| Garden model | 29×32 = 928 cards | 28 over limit | 30×32−32 = 960−32 = 928. |
| Mini museum | 42×21 = 882 cards | Fits; 18 below limit | 42×(20+1) = 840+42 = 882. |
| Garden revision | 28×32 = 896 cards | Fits; 4 below limit | 28×(30+2) = 840+56 = 896. |
| Guided Day 15 | 33×26 = 858 cards | Fits; 42 below limit | 33×(20+6) = 660+198 = 858. |
| Guided Day 20 | 22×41 = 902 cards | 2 over limit | 22×(40+1) = 880+22 = 902. |
| One possible Day 20 revision | 21×41 = 861 cards | Fits; 39 below limit | 22×41−41 = 902−41 = 861. Other transparent valid revisions accepted. |
What to look for each day
| Day | First evidence worth keeping | If it goes wrong, teach this next |
|---|---|---|
| 11 | Two facts tied to Source A, one flyer overclaim and an answerable question. | If cards become visitors, re-label the two table columns and have child point to the missing visitor count. |
| 12 | Benchmark before product, rounding direction and a statement that a coarse estimate does not settle a close cap. | If 25×40≈1,000 is treated as proof that 24×37 fails, calculate the exact plan and compare the two claims. |
| 13 | Product parts keep tens value, label cards, and a 900 comparison. | If 46×18 is read as 46+18 or 460+36, rebuild 46 groups of 10 and 8 symbolically. |
| 14 | 928 > 900; flyer arithmetic corrected without making a claim about real visitors. | If a neat poster is accepted as evidence, ask the child to show the factor row and product first. |
| 15 | Guided 858 and a source-bound sentence after the separate subject checks. | If answer copied from a group, invite a new method individually; do not relabel this as an independent check. |
| 16 | Two imagined priorities are paraphrased without a fake survey. | If “everyone prefers” persists, underline “I might” and the no-survey note in Source A. |
| 17 | 888÷24=37 or a genuinely different recomputation; a bound exposes 8,880. | If the inverse is merely copied, ask what the quotient counts and rebuild one box/group. |
| 18 | Original 29×32=928 is separate from revised 28×32=896; ? is tray count. | If 29×32=896 is written, keep both rows visible, circle the changed factor, then substitute. |
| 19 | Choice, product, cap, source scope, another possible view, unknown and deliberate revision. | If the pitch is polished but uncheckable, ask visitor to reproduce the calculation and locate the source row. |
| 20 | 902 is over; a labelled revision works; conclusion stays within the model. | If a child asserts real cost or safety from cards, ask which source would be needed and save that question. |
A child may reasonably reject the suggested garden revision because fewer trays might not represent every invented plant category; the card model alone does not settle that design concern. Other corrected plans are acceptable with accurate calculations and a newly stated meaning. The imagined reader's access priority deserves attention but this pack cannot certify any real access feature. A spoken-presentation outcome requires actual observed delivery, not just a written script. Gather multiple samples before making any achievement judgment.
