I use this activity as a review for our multiplying and dividing rational numbers assessment. There are multi-step problems included, which incorporate addition and subtraction of rational numbers as well, but the majority of the problems are focused on multiplication and division of rational numbers. This activity contains four different sets of problems (with 5 problems in each set). The sets vary in their level of complexity, which allows you to differentiate the practice based on your students' understanding of the concepts. The students complete their set of 5 problems independently, and then meet with the classmates who completed the same set of problems, to compare their answers and problem solving strategies. This activity is a good way to have the students practice with the concepts independently, but also have an opportunity to collaborate, check their work, and explain their thinking.
*Note: The 4th (most challenging) set of problems includes some problems that involve simplifying radicals. This set of problems can be eliminated, if this is not a concept that applies to your students' work*
