This lesson builds number sense with the aid of the 100 Chart by focusing on number patterns, number relationships, and the connection between tens and ones. To explore number relationships on the chart, students find target numbers and solve number riddles using more than, less than, between, and closer to.

Content in this Lesson

  • Representing and identifying numbers to 100 using the 100 Chart [E1].
  • Comparing quantities and representing that relationship using less than, greater than, between, and closer to [E3].
