"…the results from the National Assessment of Educational Progress (NAEP) estimation items… point out the weak estimation skills of our students as well as a basic conceptual misunderstanding of fractions, decimals, and percents. Unless this conceptual error is corrected, students will continue to struggle with estimating." (Reys, 1986)

Estimation is more than just ‘rounding numbers’—it’s a bigger and more useful topic than you might think! We use estimation more than we realize when making calculations and decisions in our daily life and at work. Explicitly teaching students to compute mentally and approximate answers develops their number sense and their confidence in using math.


    This professional development activity/course is designed for:

  • Adult basic education teachers at all levels of math background and comfort

In this 75-minute webinar, we will discuss different types of estimation (numerosity, measurement, and computation estimation) and how to integrate them in your instruction to help students develop number sense.

Please note: About one week before the event, registrants will receive a separate email from the SABES Math Team at TERC ( with instructions on how to access the Zoom session. 

    Learning Objectives

    Upon completion of this professional development activity/course, you will be able to:

  • Describe several types of estimation
  • Give examples of calculation estimation strategies other than rounding
  • Use resources to incorporate estimation instruction into your teaching
