Mathematics | Grade : 2

Domain - Operations and Algebraic Thinking

Cluster - Work with equal groups of objects to gain foundations for multiplication.

[2.OA.C.3] - Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.

Predecessor Standards:

  • 1.OA.D.7
    Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

Successor Standards:

  • 3.OA.A.1
    Interpret products of whole numbers, e.g., interpret 5 x 7 as the total number of objects in five groups of seven objects each. For example, describe a context in which a total number of objects can be expressed as 5 x 7.
  • 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.

Same Level Standards:

  • 2.NBT.A.2
    Count within 1,000; skip-count by 5s, 10s, and 100s. Identify patterns in skip counting starting at any number.
