A great formative assessment that encourages lots of peer dialogue. Students solve sets of problems involving operations with rational numbers. Consider posting the problem sets around various areas of the classroom, as students use the provided template for showing work. Use as a more formal assessment, or cooperative classwork. My favorite thing about this format is the math communication that occurs between students!
Two versions are included - one version is black-and-white, designed to be photocopied with problem sets posted on classroom walls. The other version is full-color, and each problem set can be accessed by students by scanning the colored QR-codes included. Students have access to the problems sets on a mobile device and enjoy the suspense of scanning the QR-code to see what it reveals!
Both problem-set versions have their own black-and-white paper-copy templates for student work. Great with or without iPads!
