BRIJBOX · MORE, FEWER OR THE SAME · PAIRING MAT

One partner each.

Put one counter in each box, one kind along the top row and the other along the bottom. Partners sit in the same column. Whatever is left with an empty box below or above it has no partner — and that is the answer. No printer? Two hand-drawn rows work just as well, and so does pairing the counters straight on the table.

The boxes are the same size all the way along, so a row that looks longer really does hold more. When you compare counters that are not on the mat, spacing can fool the eye — that is exactly what this lesson is about.

BRIJBOX · MORE, FEWER OR THE SAME · THREE COMPARISONS

Which row has more?

Cut out each pair of rows. For each one, give every hollow circle a solid partner, then ring anything left without one. Say which row has more, which has fewer, or whether they are the same. One of these three is a pair of equal rows — the spacing is there to mislead you.

Reading a pairing that is already made is not the same as making one. The pairing your child builds with real counters is the evidence.

Trust the partners, not the look.

Ten counters of one kind and ten of another, plus a cloth. App 2–3 min → table 9–11 min → app practice 2–3 min. The table is the longest part, and these are estimates, not deadlines. The mat and the counters are the complete no-device route.

1. Two loose clusters: 6 blue, 4 red. “Are there more blue counters or more red counters?” A guess from the look is a fine entry. Then: “How could we be sure?”
2. Model two partner pairs; your child pairs the rest. “Which counters have no partner?” Read the picture together: leftovers mean more, and running out means fewer.
3. “So — more blues or more reds?” … “And fewer?” Then bring out the 5-and-5 sets: pair them, discover they are equal, and supply the word equal once if it is new.
4. Transfer: keep the same 6 and 4. In full view, stretch the four into a long line and cluster the six. “Now — are there more reds or more blues?” If the answer is “red”, say only “Be sure.” — their next move is the evidence. Close by respacing one equal set: “Still equal?”
5. Sitting boundary: a coherent stop is after step 3; step 4 then takes a flexible sitting, re-entering by rebuilding the pairs.

What did you notice?

The practice items here present pairings that are already made, so they are receptive rehearsal — reading a pairing is not the same as constructing one. Constructing pairs is table evidence, and it lives on your paper card.

• Pairs two sets one-to-one: one partner each, completely, without prompting.
• Reads leftovers as more or fewer: points to the leftovers as the reason.
• Identifies equal sets: says same or equal when the pairing exhausts both.
• Spacing transfer: keeps or re-derives the answer with pairing, counting or conservation reasoning — including a self-chosen check after the neutral “Be sure.” Note the initial slip; it is still independent.

Record which method your child treats as their own proof — pairing, counting or both. If the mathematics is right but the words are crossed, ask “show me the set with more”: that separates vocabulary from concept. Nothing is scored or stored.
