They get pretty into it, so I decided to go ahead and make a Halloween - themed version of the equation picture challenges I wanted to make.
My goal for these is to practice algebraic concepts in a different format. These are great for practicing substitutions (an awesome lead-in to solving systems of equations).
But they can also be an application of the transitive property in some cases on the challenging level of the cards.
These are great for partner work, because they can talk through different methods of solving (so common-core-friendly!).
You can also try using one each day during the week of Halloween as a warm-up.
I included an easier set of 4 problems for younger students too (or a basic starter set before using the 4 challenging ones).
