What educators are saying

Students loved referring back to this resource hanging above my whiteboards. Often I would catch them checking themselves to make sure they were correct without using a calculator. Great for building confidence.
This is probably the best and most used thing on my wall this year. My kids depended on it when estimating and were very upset when I had to cover it for state testing…definitely never coming down!

Description

This is ideal for beginning to teach approximating square roots! You can hang this number line in your classroom all year or just get it out as you start to estimate square roots of non-perfect square.

Simply print the 5 pages and tape them together to create a number line that goes from 1 to 15. NEW! Now, you can also include negative numbers. Print the additional 5 pages to include numbers -14 through 0.

There are 2 versions.

  • 1 version with the integer equivalents
  • 1 version with just the square roots of perfect squares

Check out the preview to see more.

You can laminate it and use dry-erase markers to plot points. Use this to help students use rational approximations of irrational numbers and locate them approximately on a number line.

This is math classroom décor with a purpose! I love hanging this above my board so students can reference all year... even before they even know what those radical symbols mean.

Get number line displays for both square roots and cube roots and save with this Square Roots & Cube Roots Number Lines Bundle.

Standards

to see state-specific standards (only available in the US).
Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π²). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
