    Description

    Get BOTH the Square Roots Number Line and the Cube Roots Number Line to display in your classroom! These can be hung in your algebra classroom all year or only used when teaching irrational numbers on a number line.

    Square Roots Number Line: 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 decor 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.


    Cube Roots Number Line: This is ideal for beginning to teach approximating cube roots! You can hang this number line in your classroom all year or just get it out as you start to estimate cube roots of non-perfect cubes or other irrational numbers. Simply print the 4 pages and tape them together to create a number line that goes from 1 to 10.

    There are 2 versions.

    • 1 version with the whole number equivalents
    • 1 version with just the square roots of perfect cubes

    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.

    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.
    Use square root and cube root symbols to represent solutions to equations of the form 𝘹² = 𝘱 and 𝘹³ = 𝘱, where 𝘱 is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
