B-first-Q2 · Represents 5 complete groups of 3 members, with all 15 members represented once.
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 10 whole sock-picture cards. Every complete pack needs 2 members. Make as many complete packs as possible and leave leftovers aside. How many complete packs and leftover members are there?
1. Introduce the entire new source and ask what each quantity names. Preserve a first model or explanation. 2. Use two-card pack outlines, but do not fill or number their completed count for the child. Child chooses each two-member group from the 10 and names each completed pack; track every member once. Empty outlines are not completed packs. 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 10 as the whole available collection and 2 sock-picture cards as the required size of each complete pack. Take exactly 2 at a time into a new named pack; check that size before calling it complete. There are 5 complete packs and 0 whole sock-picture cards aside. 2+2+2+2+2=10; The requested number 5 names packs; 2 names members in one pack. A leftover group of fewer than 2 is not another complete pack. Count or rebuild all original members to check; repeated addition, known groups or a supported subtraction model are possible taught methods, not a required memorised division fact.
In a separately introduced new job, 12 whole ticket marks are available. Each complete pack needs 3 members. Make as many complete packs as possible and leave leftovers aside. How many complete packs and leftovers are there?
Name 12 as the whole available collection and 3 ticket marks as the required size of each complete pack. Take exactly 3 at a time into a new named pack; check that size before calling it complete. There are 4 complete packs and 0 whole ticket marks aside. 3+3+3+3=12; The requested number 4 names packs; 3 names members in one pack. A leftover group of fewer than 3 is not another complete pack. Count or rebuild all original members to check; repeated addition, known groups or a supported subtraction model are possible taught methods, not a required memorised division fact.
For the guided source, ask the child to name the number of complete packs and any leftover, show each stated pack size and check the full whole. Focus on: Build a complete fixed-size model. Keep the model/source visible and record exact first wording, not merely a correct numeral.
On this new guided source, build a complete fixed-size model: 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.
