This is a new station for practicing problem solving.This set focuses on subtracting rational numbers and includes four different Poly Problem Solvers, each with eight problems. Students solve the problem and match the answer to it. I suggest using hook and loop tabs. This way, students can actually stick the solutions next to the problems. There are two extra answers in each case, so that student must solve the last problem rather than use process of elimination.
My station rotations are in groups of four. I like to use these as a partner station. That is, when the group gets to this station, they work in partner pairs on two different Poly-Problem-Solvers. They can switch if both partner pairs finish with time left at the station. You could also have the students work individually or in groups of four. There is a sheet for students to show their work.
I have included two versions. In the first, the problems and answers are in corresponding colors. That way, if a student drops an answer, you know which Poly Problem Solver it belongs to. In the second version, all the problems and answers are in black. Here you can print them on four different colored sheets of paper. I prefer cardstock for the weight and feel, but plain copy paper works, too.
I am working on Poly Problem Solvers for many other problem solving skills. Please check back for more!!!

Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
Apply properties of operations as strategies to add and subtract rational numbers.
