Why Three-Step Sequence works

At its simplest, Three-Step Sequence is about reasoning that can be explained from visible clues or rules, starting with the instruction to watch or listen to the full three-step sequence. Remember and reproduce a three-step sequence of actions, objects or symbols in the original order. The first useful comparison appears when the child then has to repeat the three steps aloud or with gestures before acting.

Set up — Watch or listen to the full three-step sequence

No special materials are needed before the child is asked to watch or listen to the full three-step sequence. Complete the opening request to watch or listen to the full three-step sequence once before adding the next instruction to repeat the three steps aloud or with gestures before acting. Use age-appropriate pieces and avoid small loose parts for children who may mouth objects throughout that first transition.

Step 2 — Repeat the three steps aloud or with gestures before acting

Treat the attempt to repeat the three steps aloud or with gestures before acting as a checkpoint between the earlier step to watch or listen to the full three-step sequence and the coming step to perform the first step. A perfect answer is not required.

Step 3 — Perform the first step

After completing the instruction to perform the first step, pause and ask what changed from the earlier step where they had to repeat the three steps aloud or with gestures before acting. Use that answer to decide whether they are ready to continue with steps two and three in order.

Step 4 — Continue with steps two and three in order

Keep the adult prompt brief while the child tries to continue with steps two and three in order. If needed, return to the earlier step to perform the first step before asking them to compare the completed sequence with the original model.

Step 5 — Compare the completed sequence with the original model

Keep the pace slow while the child tries to compare the completed sequence with the original model. If the effect is hard to see, simplify that action before continuing with the instruction to compare the completed sequence with the original model.

What to notice before Compare the completed sequence with the original model

The strongest evidence appears after the child has tried to perform the first step and before they finish by trying to compare the completed sequence with the original model. Look for which clue, position, or relationship supports the answer rather than judging the round by speed or neatness.

Make Perform the first step easier or harder

Use the child’s last successful attempt to perform the first step to set the next round. Simplify by doing this: use fewer items and make the relevant difference more obvious. Extend it by doing this: add one plausible distractor, remove one cue, or ask the child to explain the rule.

Finish after Compare the completed sequence with the original model

Compare the completed sequence with the original model. Close on that result so the child leaves with one clear idea from the activity. For another activity, use the activity search or create one with the activity generator.
