Lesson objective: Relate comparing objects to comparing numerals to determine which has a greater or lesser value.  

This lesson provides an opportunity for students to apply their knowledge and understanding of comparison of numbers presented as written numerals to a real-life connection to which students can relate. Students are asked to compare who scored more or who scored less between team members of a soccer team.  

 Key Concept students will understand that: 

  • Written numerals can be compared using the language greater than, less than, or equal to.

Skills students will use:

  • Counting and matching strategies to support their understanding of comparing numerals.
  • The number path and counting sequence to support understanding.
  • Comparison language of greater than, less than, and equal to, when explaining their reasoning.

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they apply and extend their understanding of comparing with objects to comparing written numerals. They also apply Mathematical Practice 6 (Attend to Precision) as they use correct comparison language: greater than, less than, and equal to. Students may rely on counting and matching strategies and the counting sequence as they transition to comparing written numerals.  

Key vocabulary:

  • compare, comparison
  • counting, counting sequence
  • equal, equal to
  • greater, greater than
  • less, less than
  • more, more than
  • number path
  • same

Special materials needed:

  • number path (optional)
  • ten frames (optional)
  • counters or connecting cubes for support

For additional practice:

  • numeral cards with ten frames
  • numeral cards
  • game directions... Number Compare: Who has More? and Number Compare: Who has Less?
