3.OA.D.9 (Operations and Algebraic Thinking): Find patterns in numbers, such as a rule that adds or subtracts the same amount, and explain why they work.
About this standard
Third graders look for patterns in numbers and explain why they happen, such as why 4 times any number is always even. Ask your child to describe a rule in words before using it. Find adding and subtracting rules in Number Patterns: Find the Rule, and work with division rules in Division Input-Output Tables.
