Chapter 3 Problem Solving with Units
In this No Prep Math unit, high school students will review basic unit conversion and dimensional analysis and solve challenging real-world and mathematical problems using estimation and dimensional analysis techniques. High-school students at all levels will be challenged by problems in this unit.
Most lessons are intended to take one 45-minute class period for notes, however you may decide to go faster or slower depending on the needs of your students. The notes include a brief review of basic unit conversion followed by more challenging multistep modeling problems. Homework assignments tend to include a brief review of skills and one or two challenging problems for a total of 8 to 10 problems. If your students are not familiar with unit conversion, then you may need to supplement with other resources containing more skills practice. One activity, an optional project, two quizzes, a chapter test, suggestions for additional activities, and answer keys for the notes, assignments, and assessments are included in the full unit.
