Learning about distance, rate and time is part of the curriculum on ratios in 6th grade general mathematics. Students determine the distance traveled, rate of speed and time given various components of word problems. Units of distance and time i.e. miles, seconds, as well as speed, miles per hour are calculated depending on the problem presented to the student. Typically at the 6th grade level, students are asked to determine the distance traveled given rate and time. As students become comfortable with this calculation, the unknown variable changes from distance to time and speed. Students must manipulate the equation to solve for the variable. Students are encourage to use the Magic Triangle to help solve these types of problems. Units of measure must be paid close attention as problems will ask for conversions of measurement. As the questions become more complex, students in subsequent lessons will learn about the DRT table. For this specific lesson:
1.1 Students will identify and briefly explain the distance formula
1.2 Understand the vocabulary associated with the lesson: distance, rate and time
1.3 Compute or calculate the distance, the rate or the time
Identified Academic Language:
Distance
Speed
Average Speed
Time
Distance Formula: Distance (D) = Rate (Speed) x Time (T)
