Here's a great review activity for writing and solving two-step equations and using formulas (distance formula and Fahrenheit to Celsius formula). There are four stations each containing 3 or 4 review problems where students decode a puzzle using the answers to the problems. Real world problems involving positive rational numbers (whole numbers, decimals and fractions). Answer key is included. If you'd like the Word version of the document, just message me after purchasing, and I'll email it to you.
