C-later-Q2 · Represents all 19 members exactly once across 4 equal recipient groups of 4 and a separate 3 leftover group.
Teach this particular missing component with a new ordinary job after retaining the held first response. The previous answer/source is not silently edited into a new independent sample.
Read the exact original response and separate access support from mathematical hints. Check counting the fresh whole and understanding the named unit. Offer a small new four-member/two-place or six-member/two-per-pack introduction if this representation is new; do not require fluent symbolic division.
Plain paper, a pencil or child-directed marks, safe large pieces and named places. A place can be a drawn box or spoken label. No food, real money, purchase, printer, account or device required. A helper moves only the piece/place the child chooses.
About 8–12 minutes, unpiloted; split or stop as needed.
A new pretend collection has 15 whole landmark-picture cards. Share equally between 4 named places, as many whole members per place as possible, leaving leftovers aside. How many go to each place and how many remain?
1. Introduce the entire new source and ask what each quantity names. Preserve a first model or explanation. 2. Use four named places and 15 members. After three complete rounds twelve are assigned and three remain aside. Each place has 3; the separate 3 leftovers are not a fifth recipient share. Label both quantities because their numerals match but meanings differ. 3. Teach with the separate worked possibility below only after that first attempt. Invite the child to direct a different coherent model; do not require a faster strategy or a repeated physical action. 4. Introduce the full different guided source, not just new numerals. Let the child first choose a representation and label the requested quantity. 5. Recheck the precise new-source component, record actual support and choose another fresh opportunity later if needed.
Name 15 as the whole collection and 4 as the known number of recipients. Deal one landmark-picture card to each recipient in a complete round, or make a different equal-allocation model the child can explain. After 3 complete rounds each recipient has 3 landmark-picture cards; 3 whole landmark-picture cards remain aside. Check every recipient has the same amount and that every member of the original collection is in exactly one recipient place or the leftover place. The collection check is 3 + 3 + 3 + 3=12, then 12+3=15. The requested answer names an amount per recipient, not the total or number of recipients. Do not split a whole card or invent more members; another fairness arrangement would need a different agreed job.
In a separately introduced new job, 19 whole library cards are shared equally between 3 places, as many whole members per place as possible, with leftovers aside. How many go to each and how many stay aside?
Name 19 as the whole collection and 3 as the known number of recipients. Deal one library card to each recipient in a complete round, or make a different equal-allocation model the child can explain. After 6 complete rounds each recipient has 6 library cards; 1 whole library card remains aside. Check every recipient has the same amount and that every member of the original collection is in exactly one recipient place or the leftover place. The collection check is 6 + 6 + 6=18, then 18+1=19. The requested answer names an amount per recipient, not the total or number of recipients. Do not split a whole card or invent more members; another fairness arrangement would need a different agreed job.
For the guided source, ask the child to name the per-recipient amount and any leftover, show equal groups and check the full whole. Focus on: Track equality and leftover membership. Keep the model/source visible and record exact first wording, not merely a correct numeral.
On this new guided source, track equality and leftover membership: show the exact requested relationship and unit using the complete stated collection; keep equality or the required pack/kit structure and any leftover explicit. This is the guided source criterion, not a demand to answer the old held case.
A later new small source may change the named purpose or one stated quantity. Introduce it whole, check its intended relationship and criterion before use, and keep it as a separate dated record. A prompted correction now is supported teaching, not proof of unseen transfer.
Let the child mix objects, a drawing, speech, signing, AAC, tactile marks or an exact directed helper. Read the whole source and allow processing time. Offer a quiet seated route and a pause. Record reading/motor access separately from hints that choose a mathematical step. These are choices, not fixed learning styles or neurotype assignments.
