Why Copy the Arrangement works

Copy the Arrangement is designed to practice reasoning that can be explained from visible clues or rules through a sequence that begins when the child is asked to study which object is left, right, in front or behind. Recreate a small object arrangement with matching relative positions, distances and orientations. The opening action leads directly into the moment when the child is asked to place the first object as an anchor.

Set up — Study which object is left, right, in front or behind

No special materials are needed before the child is asked to study which object is left, right, in front or behind. Keep the space simple enough that the child can move from study which object is left, right, in front or behind to place the first object as an anchor without rearranging everything. Use age-appropriate pieces and avoid small loose parts for children who may mouth objects while the child works through the first instruction to study which object is left, right, in front or behind.

Step 2 — Place the first object as an anchor

After completing the instruction to place the first object as an anchor, pause and ask what changed from the earlier step where they had to study which object is left, right, in front or behind. Use that answer to decide whether they are ready to add the remaining objects relative to that anchor.

Step 3 — Add the remaining objects relative to that anchor

Keep the adult prompt brief while the child tries to add the remaining objects relative to that anchor. If needed, return to the earlier step to place the first object as an anchor before asking them to compare orientation and spacing with the reference.

Step 4 — Compare orientation and spacing with the reference

Keep the pace slow while the child tries to compare orientation and spacing with the reference. If the effect is hard to see, simplify that action before continuing with the instruction to adjust only the positions that differ.

Step 5 — Adjust only the positions that differ

Treat the attempt to adjust only the positions that differ as a checkpoint between the earlier step to compare orientation and spacing with the reference and the coming step to adjust only the positions that differ. A perfect answer is not required.

What to notice before Adjust only the positions that differ

Use the attempt to add the remaining objects relative to that anchor as the observation point. If the child understands why they are next asked to compare orientation and spacing with the reference, the final request to adjust only the positions that differ should feel connected.

Make Add the remaining objects relative to that… easier or harder

A shorter version can finish after the child has tried to add the remaining objects relative to that anchor, using this support: use fewer items and make the relevant difference more obvious. An advanced version can continue to adjust only the positions that differ after you add one plausible distractor, remove one cue, or ask the child to explain the rule.

Finish after Adjust only the positions that differ

Adjust only the positions that differ. That completes the core sequence; no extra finale is needed. Browse the activity search for a different mechanic, or use the activity generator.
