Home 38 · Count each bundle
Try one little turn.
Prepare: Describe five fictional paper bundles with counts 0,1,1,3,3.
Invitation: Ask how many bundles have each count. Use safe real large paper bundles only if wanted and suitable.
Adult model/check: MODEL 0→1 bundle,1→2,3→2, total 5 bundles;8 pieces altogether. Zero is a known empty bundle; missing information is different.
Observe and respond: Ask for one useful reason; keep the child's response as actually made. If count and frequency merge, name one bundle’s count first, then count bundles with that value.
Usual communication, wanted exact scribing, private/untimed work, rest and stopping are welcome. No purchase, photo or upload. A model is not an observation of your home; actual child mathematical choice, helper physical action and any real willing-reader trial are separately named.
