Georgia 1.PAR.3.2
The Standard
Identify, describe, and create growing, shrinking, and repeating patterns based on the repeated addition or subtraction of 1s, 2s, 5s, and 10s.
Georgia's K-12 Mathematics Standards · Identify, describe, extend, and create repeating patterns, growing patterns, and shrinking patterns found in real-life situations.

What This Standard Means
What Students Need to Do
- Students find the part or change that repeats in a pattern. They tell whether amounts stay in a cycle, grow, or shrink. They count forward or backward by 1, 2, 5, or 10 to continue and make patterns.
What Mastery Looks Like
- Given 7, 9, 11, a student states the rule is add 2 and writes 13 and 15. Given 40, 30, 20, they state subtract 10 and continue accurately. They can name a repeated unit and create a new pattern that follows a stated rule.
Common Misconceptions
- Students may choose a rule from only the first two terms and ignore a later mismatch. They may count by 5 as 5, 15, 25, skipping numbers that end in 0. They may call a growing sequence repeating because the same operation is used each time.
How to Assess It
- Exit ticket: Complete 32, 30, 28, __, __, then write the rule and circle growing, shrinking, or repeating. Create a four-term pattern that uses repeated addition of 5.

Ways to Teach It
Build cube towers with 2, 4, 6, and 8 cubes, then ask partners to make and explain the next two towers.
Display 25, 20, 15, 10 and ask, “What changes each time, and how do you know what comes next?”
Play Rule Card Match: students pair sequence cards with add or subtract 1, 2, 5, or 10 rule cards.
Model a snack shelf with 50 items and remove 10 daily, recording the amount left after each day.
