I was happily distracted this morning by this lovely problem, Create a System of Two Equations by Daniel Luevanos on Open Middle, accessible for students yet such a great task for mathematical thinking. We could discuss inequalities here as well as simultaneous equations.

Noting the link to a Desmos page as a suggested answer I couldn’t resist creating a more general Desmos page.

Graspable Math created a canvas for this problem, in class we could have this available as well as Desmos. Note the scrub feature.

Now we could systematically change one variable at a time and start talking about inequalities….

If you are not familiar with Open Middle do explore these excellent problems; you can read more about the type of problems you will find on the site on the About page.
