What This Standard Means
What Students Need to Do
- Students notice when the same calculation or structure appears across several steps. They use that repetition to create a rule, make a shortcut, or check whether an answer makes sense.
What Mastery Looks Like
- Students identify what changes and what stays fixed across repeated steps. They write a general rule, test it with several cases, and use it to solve efficiently.
Common Misconceptions
- Students may guess a rule from one or two cases without checking later cases. They may describe how to get the next value but cannot write a rule for any value.
How to Assess It
- Give the sequence 7, 11, 15, 19. Ask students to write a rule for term n and explain which repeated calculation supports it.
