What This Standard Means
What Students Need to Do
- Students notice what stays the same when they solve several similar problems. They use that pattern to predict an answer and explain their shortcut or rule.
What Mastery Looks Like
- A student notices, for example, that adding 1 gives the next counting number and uses that idea on a new problem. They explain the rule with objects, drawings, or numbers.
Common Misconceptions
- Students may name a visual pattern but miss the number relationship. They may claim a rule after one example or repeat steps without explaining why they work.
How to Assess It
- Show 4 + 1, 5 + 1, and 6 + 1. Ask students to solve 7 + 1 and draw or write what they noticed.
