Why Pattern Copy works

At its simplest, Pattern Copy is about reasoning that can be explained from visible clues or rules, starting with the instruction to look at one complete repeat of the model. Copy a visible repeating pattern exactly, preserving both element order and the point where the repeat begins. The first useful comparison appears when the child then has to name the repeating unit.

Set up — Look at one complete repeat of the model

No special materials are needed before the child is asked to look at one complete repeat of the model. Complete the opening request to look at one complete repeat of the model once before adding the next instruction to name the repeating unit. Use age-appropriate pieces and avoid small loose parts for children who may mouth objects throughout that first transition.

Step 2 — Name the repeating unit

Allow room for a mistake while the child tries to name the repeating unit. A self-correction here is more useful than fast repetition before the child moves on to reproduce the first unit beside the model.

Step 3 — Reproduce the first unit beside the model

After the child tries to reproduce the first unit beside the model, ask one brief question about the result. Connect their answer to the next request to continue the pattern for at least two more repeats rather than explaining it for them.

Step 4 — Continue the pattern for at least two more repeats

Have the child continue the pattern for at least two more repeats before offering a solution. What happens here should help them understand how to compare the copied pattern position by position, especially compared with the earlier request to reproduce the first unit beside the model.

Step 5 — Compare the copied pattern position by position

Give the child time to compare the copied pattern position by position and notice the result. The following instruction to compare the copied pattern position by position should use what they learned after previously trying to continue the pattern for at least two more repeats.

What to notice before Compare the copied pattern position by position

The strongest evidence appears after the child has tried to reproduce the first unit beside the model and before they finish by trying to compare the copied pattern position by position. Look for which clue, position, or relationship supports the answer rather than judging the round by speed or neatness.

Make Reproduce the first unit beside the model easier or harder

Use the child’s last successful attempt to reproduce the first unit beside the model 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 copied pattern position by position

Compare the copied pattern position by position. Use that result as the stopping point for Pattern Copy. Browse the activity search for a different mechanic, or use the activity generator.
