Teacher copy · prompts and answer keys

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.

This file has every worked check. Learner files deliberately have no link to it. A learner may use speech, signed/typed language, pointing, AAC or a partner acting as hands. Record access support separately from mathematical prompts. Alternative maps/strategies are valid when they satisfy all stated constraints. Never reduce a child's judgement to one total mark; use the next-move table.

Daily exits

Day Expected evidence Immediate next move if uncertain
11 D4 seats; not directly below shade tree D2 because open D3 lies between. Trace column D and rows 2–4; ask what is named and what is open.
12 Compost B4 is one column left and one row above storage C5, using storage as reference. Put labelled tokens on both cells and name which is the reference.
13 Centre mat B2, shade A2, notice B3. Place centre first; read one relational clue at a time.
14 Tool shed B2 is above compost B4 in the same column, but not directly: B3 intervenes. Put a token on each row of column B to clarify distance.
16 43 020 = 4TT 3Th 0H 2T 0O; empty hundreds and ones; read “forty-three thousand and twenty.” Align all five place cards, including zero placeholders.
17 50 080 > 50 008; equal through hundreds, then 8 tens > 0 tens. Compare left to right in aligned columns.
18 156 + 278 = 434; ones 6+8=14, tens 5+7+1=13, hundreds 1+2+1=4. Rebuild the newly exchanged hundred.
19 503 − 268 = 235; 235 + 268 = 503. Show 503 as 4H9T13O, then remove 2H6T8O.

Thirty practice routes · worked responses

Card Answer or one valid response
D11-A Storage C5, notice board C1; both are column C.
D11-B Any two of water point E1, art wall E3, recycling E5; column E alone names five cells, three of them landmarks.
D11-C Garden bed A3, meeting mat C3; garden bed is left of mat on row 3, with B3 between.
D12-A Shade tree D2 is one column right and one row above meeting mat C3.
D12-B Tool shed B2 is two rows above compost B4 in the same column, not directly above.
D12-C Art wall E3 is right of garden bed A3 in the same row, four columns apart; reversed, garden bed is left of art wall.
D13-A Hub B2, water B1, art C2. Key names each marker.
D13-B Quiet spot A2, plant A1, books B2.
D13-C Recycling C3, bench B3, gate B2.
D14-A Original is false; E1 water point is right of C1 notice board in the same row, two columns apart.
D14-B “Below” is true; “directly” is false. Seats D4 are two rows below shade tree D2, with D3 between.
D14-C Open; look for a first plan whose meaning cannot be independently decoded, then a revised labelled key that makes all three landmarks identifiable. The teacher need not make a child deliberately draw a confusing plan if they can explain what is missing from an unkeyed version.
D15-A Compost B4; e.g. one column left and one row below meeting mat C3.
D15-B Centre table B2, door A2, window B3; friend can recover all three from words.
D15-C Open; both statements must be testable on Map A, and the false one repaired without changing the map invisibly.
D16-A 21 408 = 2TT 1Th 4H 0T 8O = 1TT 11Th 4H 0T 8O; 10 000 + 11 000 + 400 + 8 = 21 408.
D16-B 35 071 = 3TT 5Th 0H 7T 1O = 2TT 15Th 0H 7T 1O; total unchanged.
D16-C 18 205 = 1TT 8Th 2H 0T 5O = 0TT 18Th 2H 0T 5O; 18 000 + 200 + 5 = 18 205.
D17-A 40 250 > 40 205; first difference is tens: 5 tens versus 0 tens.
D17-B 60 120 > 60 012; first difference is hundreds: 1 hundred versus 0 hundreds. In 60 012, hundreds place 0, tens 1; in 60 120, tens 2 and ones 0.
D17-C 42 500 > 42 050; hundreds 5 versus 0. Example exchange for 42 050: 4TT 2Th 0H 5T 0O = 3TT 12Th 0H 5T 0O.
D18-A 234 + 189 = 423 bookmarks; ones and tens exchanges, estimate about 420.
D18-B 367 + 158 = 525 cards; ones and tens exchanges, estimate about 530.
D18-C 408 + 176 = 584 tags; ones exchange 8+6=14, then tens 0+7+1=8, hundreds 4+1=5. Estimate about 580.
D19-A 804 − 376 = 428 squares; 428 + 376 = 804. Exchange 804 to 7H9T14O.
D19-B 730 − 284 = 446 markers; 446 + 284 = 730. Exchange one T into ten O: 7H2T10O, then one H into ten T: 6H12T10O.
D19-C 612 − 275 = 337 slips; 337 + 275 = 612. Exchange to 5H10T12O before removing.
D20-A 52 610 = 5TT 2Th 6H 1T 0O = 4TT 12Th 6H 1T 0O.
D20-B 508 − 179 = 329 badges; 329 + 179 = 508. Exchange to 4H9T18O.
D20-C 38 470 > 38 407, tens 7 > 0 after earlier places tie. Example 38 407 = 3TT 8Th 4H 0T 7O = 2TT 18Th 4H 0T 7O.

Day 15 held-out check · Map B

Item Worked response What to observe
1 C2 demo; column C and row 2 cross there. Interprets new top view/legend.
2 Art table D3 is right of book stall B3, in the same row, with open C3 between; not directly next to it. Uses a named reference and precision about separation.
3 On the new 3 × 3: rest B2, water B1, art C2; key labels all three. Creates a representation from constraints that a follower can decode.
4 Original false: quiet area A2 is left of demo C2, two columns away, not right. Keep reference as demo. Tests and repairs a positional claim without changing the data.

The check uses a new fictional makers' fair, not Map A. Read labels neutrally; pointing at a target would be a mathematical cue. A visual impairment or motor support route may use the same 25-cell relationship as tactile squares. Record if the check extends beyond the allotted 10 minutes.

Day 20 held-out check · stock and regrouping

Item Worked response What to observe
1 Read “forty-one thousand, two hundred and five.” 41 205 = 4TT 1Th 2H 0T 5O; zero holds the tens place. Naming, writing and representing beyond 10 000.
2 41 205 = 3TT 11Th 2H 0T 5O; 30 000 + 11 000 + 200 + 5 = 41 205. One ten-thousand becomes exactly ten thousands; quantity conserved.
3 41 250 is greater: TT, Th and H tie, then 5 tens > 0 tens. Orders by highest differing place.
4 624 − 187 = 437 blank cards remain. Exchange 6H 2T 4O → 5H 11T 14O, subtract 1H 8T 7O, then check 437 + 187 = 624. Count-up path 187→200 (+13)→600 (+400)→624 (+24) also totals 437. Three-digit regrouping and contextual/checking sentence.

Formative rubric and next moves

Use this for map interpretation, relative relation, map creation/repair, five-digit place, exchange, and three-digit calculation separately. It is a teaching record, not an end-of-year ACARA judgement.

Evidence seen Record Next move
Independent, checkable model plus an accurate reason I and one exact example Offer another layout/number; ask child to test a peer's description or prove an alternative strategy.
Accurate only after a mathematical prompt (“which is the reference?”, “count the ten strips”) P and prompt wording Start next small group with the same material but a fresh example, then fade cue and resample.
Specific mismatch (reversed reference, “directly” misused, key absent, zero omitted, exchange of one instead of ten, wrong regrouped total) R and work sample Use the matched repair below; retain first and revised attempts.
Not yet seen, incomplete, or access format unavailable N and why Offer an accessible quiet attempt later; do not score a blank as misconception.

Targeted repairs:

For family feedback, give a small next task (“test whether a landmark is directly left” or “exchange ten ones for one ten”), never a fixed ability label. Retain or photograph child work only under the school's privacy practice, without real school plans or names in this pack.
