Unit of InstructionFocus 3: Percents & Focus 5: Samples/ Populations
Standard(s) Taught

MAFS.7.RP.1.3

Use proportional relationships to solve multi-step ratio and percent problems.

MAFS.7.SP.1.1

Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

MAFS.7.SP.1.2

Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.

Learning Targets and Learning Criteria

Students are successful when they can…

  • use proportional reasoning to solve real-world ratio problems, including those with multiple steps.
  • use proportional reasoning to solve real-world percent problems, including those with multiple steps, such as markups, markdowns, commissions, and fees.
  • critique examples of random sampling as statistical tools using precise mathematical vocabulary: random sampling, population, and valid generalizations.
  • design random samplings to collect the data given statistical questions.  Defend the samplings as random.
  • draw valid inferences and generalizations from random samplings of populations and justify the inferences and generalizations as valid using appropriate vocabulary.
  • explain the variability in multiple random samples and gauge how far off an estimate may be.
