Do you want to help your students to become fluent in math by developing number sense? This Sieve of Eratosthenes lesson will do just that.

It includes two printable activities, a lesson plan, teacher tips, and an answer key. Soon your students will be experts at numeracy and fluency!


Building numeracy and fluency is one of the most important math skills your students will learn. Use this Sieve of Eratosthenes Lesson to help them discover number patterns that can improve mental math with all four operations.

Students from elementary through high school can struggle with numeracy and fluency. Oftentimes, students are asked to memorize math facts but they fail to remember them long term.

Benefits of Using the Sieve of Eratosthenes Lesson

The Sieve of Eratosthenes complete lesson will have your students looking at multiplication in a whole new way. It’s an “open task,” meaning that each student will learn something unique.

For some, the sieve is a way to master times tables. For others, it will help with common denominators or factoring expressions. The sieve also highlights patterns that can improve mental math with all four operations.

Before I began using the sieve, many students got bogged-down trying to memorize number “facts”. They were trying to memorize them instead of finding patterns and building their numeracy and fluency.

When my students use this resource, they’re less likely to struggle with numeracy and fluency as they progress in math. This leads to an easier time thinking about numbers and number patterns.

What’s Included?

The Sieve of Eratosthenes Lesson contains:

  • Teacher tips and answer keys
  • Lesson plans
  • Two printable worksheets
  • A rubric

    I used this lesson in fully remote learning by putting the materials into a one note so that students could “ink” on it. I used part of the lesson during a formal observation, and my principal commented on how engaged my students were with the activity. My favorite thing about this resource is that it was accessible to all my different types of math scholars—they all were able to feel successful and engage their problem solving skills. I can’t wait to use this resource in person! Many thanks.

    Great opening activity for patterns and beginning of the year. My 8th grade students really enjoyed getting to color and I was happy to see all the learning going on.
