This lesson is the start of an ongoing activity in which students use the calendar to practice multiplication. Each month the class will focus on a different factor. As part of a daily routine, students will decide if that day's date is a multiple of that month's factor. Students will represent the date as a number sentence using that focus factor and drawings.

Content in this Lesson

  • Identifying multiples of the numbers 2 through 11.
  • Writing and completing open number sentences involving multiplication [E1].
  • Identifying patterns in multiples and factors.
  • Using drawings to represent multiplication problems [E2].
