Lesson: Estimating Products: Multiplying by One-Digit Numbers Mathematics • 4th Grade

In this lesson, we will learn how to estimate the products of one-digit numbers and two- or three-digit numbers by rounding to the nearest ten or hundred.

Lesson Plan

Students will be able to

  • estimate the product of a one-digit and a two-digit number by rounding the two-digit number to the nearest 10,
  • estimate the product of a one-digit and a three-digit number by rounding the three-digit number to the nearest 100,
  • use estimation to identify if an answer is reasonable,
  • use estimation to find two numbers a product is between.
