This Rounding as Estimation Mini-unit includes both print & digital resources perfect for use with a guided math model.

Rounding is so hard for 3rd graders! It is often taught as a discrete skill without the context of estimation. Since estimation is the purpose behind rounding, this unit includes 4 lessons teaching students to round to the nearest ten, hundred, thousand, and ten-thousand with up to 5-digit numbers.

Lessons Included:

  • 4.1 Rounding to the Nearest 10
  • 4.2 Rounding to the Nearest 100
  • 4.3 Rounding to the Nearest 1,000
  • 4.4 Rounding to the Nearest 10,000


  • PowerPoint Lesson: Bright, engaging digital lessons introduce and model each concept, including interactive questions and error analysis tasks to check understanding. (editable text)

  • Math Mat & Task Cards: Task cards guide students through hands-on activities designed to reinforce the concepts introduced in the Mini-Lesson. (editable questions)

  • Practice Pages: Perfect for in-class practice or homework, these activities provide plenty of support, but ask students to start demonstrating their understanding more independently.

  • Exit Tickets provide a brief snapshot of student understanding for you at the end of each math block. (editable text)


  • Quick Check (lessons 1-4 quiz with editable questions)
  • All digital options
