Three pages of worksheets that walk students through rational word problems. This is a great introductory activity because many students will be able to work through it will little or no guidance from you.
The questions include equations, tables, graphs, and critical thinking. I gave it to students in small groups so they could discuss how to answer questions, but it could also be individual work.
There is also a modified version that includes hints for the students who may need it.
The key is included, as is a link to edit the documents if you choose.
