Children can copy a red-blue-red-blue pattern without knowing what makes it a pattern. A movement or sound pattern helps them feel the repeating unit and explain the rule before they transfer it to blocks or paper.
Begin with an AB movement pattern
Clap, tap knees, clap, tap knees. Ask children what comes next and how they know. Then say the rule aloud: “One clap, one tap, and then we repeat.” Invite students to lead while others listen for a mistake. Make seated alternatives available for every movement.
Change the unit
Try clap-clap-tap, clap-clap-tap. Ask how many actions belong to one repeating group. Mark the group with a pause or a drawn bracket. Explain that the repeating unit is the smallest sequence that keeps coming back, not the entire long row.
Translate sound into pictures
Draw a hand for clap and a dot for tap. Have students build the same pattern with counters or blocks. Ask whether a blue-yellow-blue-yellow row follows the same AB structure even though the objects differ. This separates the rule from the materials.
Find and fix a break
Create clap-tap-clap-clap-tap. Ask students to identify where the rule stopped working and suggest a repair. More confident students can invent an AAB or ABB pattern for a partner. For children who need support, keep the unit short and place picture cards beside the movement cues.
Listen for students who can say the repeating rule, not just copy the next move. That explanation shows they are noticing structure rather than following along by memory.
