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.
