Lesson objective: Sort even and odd numbers by composing and decomposing a whole number of their choice.

This lesson provides an opportunity for students to apply their knowledge and understanding of even and odd numbers to a real-life situation of sorting toys. Students are asked to come up with their own number of each type of toy and sort it into a bin labeled odd or even.  

Key Concept students will use: 

  • Whole numbers are either even or odd. Even numbers can be decomposed into two equal sets, but odd numbers cannot.

Skills students will use:

  • Whole numbers can be decomposed into other whole numbers. (Grade 1, Unit 6) 
  • Decompose numbers less than or equal to 10 into pairs in more than 1 way. (Grade Kindergarten, Unit 10) 

Students engage in Mathematical Practice MP.7 (Look for and make use of structure) as they sort whole numbers by decomposing each number to decide if it is even or odd.

Key vocabulary: 

  • addend
  • decompose
  • even
  • odd
  • doubles facts

Special materials needed:

  • Connecting cubes or counters
