"I printed this on colored cardstock and laminated it. I taped the pages together, leaving a small gap. This way, it folds nicely for my files. During class, we wrote on it like the example pictured."

"I printed this and laminated so I could write right on it. It was large enough for the students to stand up and write on it as well. I placed this at one of my math stations. I printed in a bright color too. Good resource. "

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.

I love the idea of laminating this and having students be able to physically estimate a square root. Very engaging.

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.
