NEXT27 · Check a proposed whole-card share
Component and target criterion
C-later-Q3 · Rejects 5 each because four such shares need 20 members, but only 19 whole cards are supplied;4 each/3 aside fits the stated task.
Purpose
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.
Entry
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.
Materials
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.
Time
About 8–12 minutes, unpiloted; split or stop as needed.
NEXT27
A new pretend collection has 13 whole flower-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?
Five full teaching moves
1. Introduce the entire new source and ask what each quantity names. Preserve a first model or explanation. 2. A supplied claim gives 4 cards to each of four places. Build four four-member required outlines and compare their 16 spaces to the 13 available members. That proposal lacks 3 cards. Reset the 13 into 3 each/1 aside under the original rule. The empty required outlines are a comparison aid, not new actual cards. 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.
New-source adult model
Name 13 as the whole collection and 4 as the known number of recipients. Deal one flower-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 flower-picture cards; 1 whole flower-picture 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 3 + 3 + 3 + 3=12, then 12+1=13. 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.
Full different guided practice
A whole different guided try
In a separately introduced new job, 17 whole map marks are shared equally between 4 places, as many whole members per place as possible, with leftovers aside. How many go to each and how many stay aside? A pretend helper proposes five marks for each of the four recipients. Does that fit this whole job? Explain using the stated collection and rule.
Guided worked possibility
Name 17 as the whole collection and 4 as the known number of recipients. Deal one map mark to each recipient in a complete round, or make a different equal-allocation model the child can explain. After 4 complete rounds each recipient has 4 map marks; 1 whole map mark 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 4 + 4 + 4 + 4=16, then 16+1=17. 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. The supplied claim does not fit: check the complete represented collection and the exact required relationship rather than the confidence of the claim.
Observation
Read the full guided source and its stated helper claim. Invite the child to decide whether it fits and explain with a model, words or directed objects. Keep both first response and any subsequent support. Explain why a proposed equal amount is unavailable.
Guided source criterion
Explains why the specific helper claim in this new guided source fails the stated relationship, using the actual whole, requested unit and equality/complete-size/equal-kit rule. An unexplained rejection or correct numeral alone is insufficient. Keep this guided source distinct from the old held case.
Follow-up and eligibility
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.
Access choices
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.
