Domain Operations and Algebraic Thinking
Cluster Solve problems involving the four operations, and identify and explain patterns in arithmetic.
Standard Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. <span class='clarification'>For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.</span>

3.OA.D.9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.

  • Addition Patterns
