Why Object Order Memory works

Object Order Memory 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 the order from left to right. Memorize the order of a short object line and rebuild that exact sequence after it is hidden. The opening action leads directly into the moment when the child is asked to cover the line or move the child’s view away.

Set up — Study the order from left to right

No special materials are needed before the child is asked to study the order from left to right. Keep the space simple enough that the child can move from study the order from left to right to cover the line or move the child’s view away 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 the order from left to right.

Step 2 — Cover the line or move the child’s view away

After completing the instruction to cover the line or move the child’s view away, pause and ask what changed from the earlier step where they had to study the order from left to right. Use that answer to decide whether they are ready to mix the objects without removing any.

Step 3 — Mix the objects without removing any

Keep the adult prompt brief while the child tries to mix the objects without removing any. If needed, return to the earlier step to cover the line or move the child’s view away before asking them to rebuild the original order from memory.

Step 4 — Rebuild the original order from memory

Keep the pace slow while the child tries to rebuild the original order from memory. If the effect is hard to see, simplify that action before continuing with the instruction to reveal the reference arrangement or photo and compare positions.

Step 5 — Reveal the reference arrangement or photo and compare positions

Treat the attempt to reveal the reference arrangement or photo and compare positions as a checkpoint between the earlier step to rebuild the original order from memory and the coming step to reveal the reference arrangement or photo and compare positions. A perfect answer is not required.

What to notice before Reveal the reference arrangement or photo and compare…

Use the attempt to mix the objects without removing any as the observation point. If the child understands why they are next asked to rebuild the original order from memory, the final request to reveal the reference arrangement or photo and compare positions should feel connected.

Make Mix the objects without removing any easier or harder

A shorter version can finish after the child has tried to mix the objects without removing any, using this support: use fewer items and make the relevant difference more obvious. An advanced version can continue to reveal the reference arrangement or photo and compare positions after you add one plausible distractor, remove one cue, or ask the child to explain the rule.

Finish after Reveal the reference arrangement or photo and compare…

Reveal the reference arrangement or photo and compare positions. A brief look back at the result is enough before ending the session. For another activity, use the activity search or create one with the activity generator.
