Overview:

Students learn about proportions by using map scales to estimate travel distances. They use an understanding of ratios to calculate travel time using an estimated speed.

In this TV 411 activity, students watch a video clip in which two NBA stars plan a trip from Atlanta to the Basketball Hall of Fame in Springfield, MA. They learn to use map scales to estimate travel distances. They also learn to use ratios to calculate travel time using an estimated speed.

Evidence Of Student Attainment:
Students:
Given contextual or mathematical situations involving multiplicative comparisons,
  • Use unit rate to solve missing value problems (e.g., cost per item or distance per time unit).
  • Use rate language to explain the relationships between ratio of two quantities as non-complex fractions and the associated unit rate of one of the quantities in terms of the other.
Teacher Vocabulary:
  • Unit rate
  • Ratio
  • Rate language
  • Per
  • Quantity
  • Measures
  • Attributes
Knowledge:
Students know:
  • Characteristics of multiplicative comparison situations.
  • Rate and ratio language.
  • Techniques for determining unit rates.
  • To use reasoning to find unit rates instead of a rule or using algorithms such as cross-products.
Skills:
Students are able to:
  • Explain relationships between ratios and the related unit rates.
  • Use unit rates to name the amount of either quantity in terms of the other quantity flexibly.
  • Represent contextual relationships as ratios.
Understanding:
Students understand that:
  • A unit rate is a ratio (a:b) of two measurements in which b is one.
  • A unit rate expresses a ratio as part-to-one or one unit of another quantity.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.6.2.1: Define unit rate, proportion, and rate.
M.6.2.2: Create a ratio or proportion from a given word problem.
M.6.2.3: Calculate unit rate by using ratios or proportions.
M.6.2.4: Write a ratio as a fraction.

Prior Knowledge Skills:
  • Recall basic multiplication facts.
  • Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem.
  • Recognize key terms to solve word problems.
    Examples: times, every, at this rate, each, per, equal/equally, in all, total.
  • Recognize a fraction as a number on the number line.
  • Label numerator, denominator, and fraction bar.
