CCSS HS: Algebra (Reasoning with Equations & Inequalities)

Tim Brzezinski, JohnCMorris, Oct 26, 2017

This GeoGebra Book is currently a work-in-progress. It will, over the next few months, start to contain lots of discovery-based learning activities, investigations, and meaningful remediation worksheets that were designed to help enhance students' learning of algebra concepts both inside and outside of the mathematics classroom.

Graphing Inequalities on the Number Line

Directions: In the applet below, you'll see an inequality. Move the BLUE POINT above the number line below and adjust the red and blue sliders (off to the top right) so that the graph you create is the graph of the inequality shown. If you do this correctly, you'll see a "CORRECT!!!" symbol appear. If you don't see a "CORRECT" icon appear, it means your graph is not yet correct. Click on the "Generate New Inequality" button to generate a new inequality to graph. Complete this exercise AS MANY TIMES AS YOU NEED in order to master this concept.
