Success today: A child compares two sets between six and ten by counting or pairing, and explains which has more, fewer or the same even when one set is spread out.
Prepare: Two mats, 20 large counters total, cards 6–10, optional ten-frames. Set up seven objects stretched across one mat and nine close together on the other.
- Reconnect, 3 min. Show 7 and 9 in ten-frames. Ask, “Which has more? How can the empty spaces help you see?” Count both to verify.
- Model, 6 min. Show the spread seven versus the bunched nine. Think aloud: “The seven row looks longer, but length is not the number of objects. I will count each set once: seven and nine. Nine has more because nine comes after seven on our number path.” Pair objects if needed to show two extra in the nine set.
- Play: river rescue, 9 min. Two rescue teams collect 6–10 pretend supplies on separate banks. Each team arranges supplies any way, then partners compare by counting or pairing and explain. Variation: compare library books on two shelves or seeds in two planting trays. Include an equal pair, such as eight versus eight.
- Independent try, 4 min. Show eight objects spread out versus ten objects grouped tightly. Ask, “Which has more? Prove it.” Then ask for a same-size comparison if the child can manage it.
- Check and close, 3 min. Show two differently arranged groups of nine. Ask if either has more. Recount only after the child has explained.
If the child relies on area or object size: Move each object into a ten-frame or pair one-to-one. Ask what changed when the arrangement changed. If a child swaps “more” and “fewer,” identify the group first, then rehearse “this one has more; the other has fewer.”
Access routes: Use two distinct raised mat areas, grippable or magnetic objects, enlarged numerals, and a number path that can be heard or felt. Accept “nine is later than seven,” a paired leftover, or a correct demonstration as explanation.
Record: 7/9, 8/10 and 9/9 decisions; whether the explanation is counting, matching, order or appearance; support needed.
