2.OA.3 Even and Odd Numbers



This 2.OA.3 Even and Odd Numbers math standards-based Operations and Algebraic Thinking unit focuses on the Common Core math standard 2.OA.3. This asks students to determine if a number is odd or even (up to 20) and also use repeated addition to represent. There are daily lesson plans, whole group activities, partner practice activities, MATH group centers, exit slips, and assessments.


What’s included in the 3 daily lesson plans:

  • Whole group activity
  • Partner practice activity
  • MATH group: Math writing, Apply new skills, Teacher time, Hands-on math (Teacher time is differentiated learning opportunities for remediation, on-level, and enrichment.)
  • Exit slip


2.OA.3 Focus:

–First Day- Paired Up Objects Into Sets

–Second Day- Splitting Up Number Into Two Sets (Show Addition Problem)

–Third Day- Mixed Review of Determining Odd or Even

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.

The 2.OA.3 activities that are included in my short answer, centers, printables, and interactive notebooks are similar but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the ‘Apply new skills’ part of MATH groups
