    Graphing System of Inequalities – Scaffolded Handout

    Here is a document that guides students through graphing one, then the other inequality. On the second page both are graphed on the same coordinate plane.

    Introduction to 2 Variable Inequalities

    Previously, I shared how I use a Google Jamboard to introduce 1 variable linear equalities with a focus on conceptual understanding. I use the same approach for the 2 variable version (example problem below). A conceptual gap that typically arises is the students do not understand what the shading represents. This is what I am…

    For years over many settings from middle school to college I have witnessed students struggle to make sense out of inequalities like x < 4. Not only is the concept of an inequality of an inequality challenging, merely reading the symbol is problematic. This post shows an concept based approach to making sense of inequalities.…
