Help your students understand how to convert between customary units of length, weight, capacity, and time. This unit includes a pre-test, a formative assessment, and a post-test. There are also instructional elements for them to use in their Interactive Notebooks or Math Journals. If you don't use those, they can still use these charts and reminders in class. I have included practice items that can be used in cooperative learning groups or as individual activities, and Problem Solving (Word Problems). These are formatted for quick, easy grading. All answer keys are included. No Prep, just print and GO! I also offer a very similar product "Converting Metric Units of Measure", if you teach both!
