Two patterns look the same at first. What comes next?
Create two rules with the same beginning. Give a partner the beginning and ask what evidence would distinguish them.
Repeat each symbol string and compare one beat at a time.
Cut these cards apart. Use the original example first, then let a partner supply a changed case. Keep sealed/final cards with the teacher until the learner commits a rule.
Repeating rule A: AB
Repeating rule B: ABABAC
My prediction and reason:
Repeating rule A: AAB
Repeating rule B: AABAAB
My prediction and reason:
Repeating rule A: ABC
Repeating rule B: ABCD
My prediction and reason:
Matching a finite beginning does not prove two patterns will always match.
