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.

Original SubjectNest draft · educator and accessibility review pending. © NeuroForgeIO Pty Ltd 2026, CC BY 4.0. Use the child prompt strips below. The teacher privately prepares the A/B quantities in the key; do not show the keyed table during the check. Each context is imaginary. Use the comparison page or PNG for counted sets. The original paper leaf/seed symbols and PNG can be cut or copied for Week 14. Print enough copies for both sets: one sheet has twenty of each symbol, so two leaf sets of 12 and 14 need two sheets. Pre-cut for pupils who do not use scissors. These are stylised marks, not scientific illustrations or observations.

Copyable no-picture route

SET A [                              ]
SET B [                              ]

Move each object once to count: A has ____; B has ____.
Pair one from A with one from B: matched pairs ____.
Unpaired objects: A ____; B ____.
Conclusion: A has MORE / FEWER / THE SAME NUMBER as B.
My evidence: I counted / I paired / I used both.

For counting, move objects from an uncounted region into a counted region, one move per number word. For pairing, set one A beside one B and leave unmatched pieces visible. If using matching positions on the grids, fill both from top left across each row before comparing cells; otherwise use separate pairing lanes on the table. Pairing alone tells the relation, not necessarily the exact total. A final count can name each quantity. A spread-out row is not proof of more. Use tactile trays/strips, enlarged or plain-text prompts, sign/AAC, and adult movement directed by the learner where needed. Large safe counters are a better option than tiny paper pieces for learners who need a grippable object.

Child prompt strips: varied everyday places

Print or read one line at a time. Each is a pretend counter task, not a claim about an actual school, service or household.

ID Child-facing prompt
C01 Two library trolleys have return-slip counters. Which has more? Show how you know.
C02 Two art tables have paper-shape counters. Are the amounts equal?
C03 Two map routes have dot counters. Which has fewer?

C12 Two recycling posters have token counters. Which has more?

Child prompt strips: fictional paper drawings of living things

The drawings are imagined. They are useful for counting and comparison only; do not infer real plant or animal facts. Use symbols cut from paper-symbols.svg, teacher-drawn marks, or equivalent accessible tactile pieces. On cards naming a different living thing, neutral paper counters can stand for those imagined picture marks if the teacher says so; no detailed animal art is required. Change the artwork but preserve the teacher's A/B quantities.

Private teacher setup and answer key

Make A and B sets from the indicated counts. Set B spread out and A close together on C04 and L02, and reverse the layout on C09 and L07, so appearance cannot answer the task. Move/pair without adding or removing items. = means every object can have one partner; for unequal sets, the larger set has the remaining unmatched objects. Differences below count unmatched objects after maximum one-to-one pairing.

Card A B Relation Unmatched after pairing
C01 12 14 A fewer; B more B 2
C02 13 13 equal 0

Four fresh teacher checks

Do not rehearse these exact sets before checking. Prepare counters or paper symbols without numeral labels in the child's view.

Check Setup Key
F1 A 16, B 16; B widely spaced. Equal; both 16; no unmatched objects.
F2 A 18, B 20; A and B arranged differently. B more, A fewer; B has 2 unmatched after 18 pairs.
F3 A 20, B 19; use fictional paper leaf symbols. A more, B fewer; A has 1 unmatched after 19 pairs.
F4 A 0, B 13; use fictional paper plant picture symbols. B more, A fewer; 0 pairs, B has 13 unmatched.

If a fresh set is changed, recalculate and write the actual key. Keep the child's mathematical record separate from any science observation. No real plant, seed, animal or child photograph is required.
