## Grade 8 9 2 b convert rates marzano rubric course 3 florida math connectsDocument Transcript

• Grade 8: Math Course 3 TEACHER VERSIONCh 9-2 B Convert RatesPrerequisite Content:Use proportions to solve problemsConvert units of measurement within the same systemLearning Goal:By the end of this lesson, students will be able to convert rates usingdimensional analysis.More Complex Content:Use derived units to solve real-world problems.Use measurements to find area and volume.Score 4.0 In addition to Score 3.0 performance, in-depth inferences and applications that go beyond what was taught, such as the student can, without help, solve a real-life problem using derived units (such as square feet, cubic meter, miles per hour). Score 3.5 The student can, without help, convert measurements for temperature, length, weight or mass, capacity, and time, correctly from one system of measurement to another (customary to metric and metric to customary) when provided with an indirect measurement conversion table.Score 3.0 While engaged in solving measurement conversion tasks, the student demonstrates an ability to without help, convert measurements for temperature, length, weight or mass, capacity, and time, correctly from one system of measurement to another (customary to metric and metric to customary) when provided with a direct measurement conversion table. The student exhibits no major errors or omissions. Score 2.5 The student can, with help, convert measurements for temperature, length, weight or mass, capacity, and time, correctly from one system of measurement to another (customary to metric and metric to customary) when provided with an indirect measurement conversion table.Score 2.0 No major errors or omissions regarding the simpler details and processes, such as the student, with help, can convert measurements and rates involving both systems of measurement using dimensional analysis
• (litres per kilometer to miles per gallon) given a direct measurement conversion table. However, the student exhibits major errors or omissions with Score 3.0 elements. Score 1.5 The student, with help, can convert measurements within the same system using dimensional analysis (seconds per hour to hours per day) given a direct measurement conversion table.Score 1.0 With help, a partial understanding of some of the Score 2.0 elements and some of the Score 3.0 elements. The student, with help, can convert measurements within the same system of measurement (gallons to pints to cups)using unit ratios and given a direct measurement conversion table. Score 0.5 The student cannot convert measurements .Score 0.0 Even with help, no understanding or skill demonstrated.
