# Number Line Bars

This interactive online number line is the perfect tool for both virtual and in-person learning. Use it to teach many different skills ranging from counting to adding, subtraction, skip counting, multiplication, division, fractions, and more.

To use this online number line, click and drag the black box at the top to the right or left to see higher or lower numbers. Toggle the numbers that appear on the number line by clicking the white “1” in the bottom right corner. Add blocks to the number line by clicking and dragging them on or off.

You can show addition problems by dragging two different blocks onto the number line. For example, 2 + 6. If you align the blocks with 0 at the beginning, students can see that the blocks add up to 8 on the number line. You can reinforce this concept by dragging an 8 block above the other blocks and showing that it is the same length.

The online number line is also useful for teaching the concepts of zero and of negative numbers. They are clearly visible on the number line, showing that numbers are a continuum.

Invite your students to explore problems while using the interactive online number line. The manipulatives offer students a visual way to explore possible solutions.
