The Number Line question is an ideal tool for visual learning and building number sense. It allows students to plot points, inequalities, and intervals right on the number line, providing a dynamic way to explore mathematical concepts. Use this guide to get started.
Add a Number Line question.
Click directly on the number line to plot a point. (Note: When clicking and dragging points to adjust them, they will remain strictly pinned to the horizontal axis for precision).
Clicking on endpoints allows them to change from open to closed points.
Toggle the Left and Right arrow toggles to add arrows.
Customize Tick Labels: You can control the visibility of tick labels by selecting your preference in the settings. Choose from All Ticks, Whole Numbers Only, Endpoints Only, or None. (Tip: This is especially helpful if you want students to count fractional subdivisions without the labels giving the answer away!)
To remove an element, click the point or interval you would like to remove.
Graphing Compound Inequalities
For graphing compound inequalities, you can graph each part of the inequality on a separate number line to better visualize the solution set. To do this, click the plus icon at the top of the graph to add a second graph. This will give you the ability to add a second number line, allowing you to plot each individual inequality.
