Lesson objective: Apply knowledge of center and spread to solve problems using a data set.

This lesson provides an opportunity for students to apply their knowledge and understanding of describing center and spread to a real-life situation. Students are asked to analyze data and use the data to answer questions about a situation.

Key Concept students will use: 

  • measures of center and variability can be used to describe a data set

Skills students will use:

  • describe measures of center and spread 
  • find measures of center and variability (Grade 6, Unit 12)

Students engage in Mathematical Practice 3 (construct viable arguments and critique the reasoning of others) as they create a report to convince the CEO of Sharp Pencils that 60 pencils should not be included in the "Back to School Pencil Pack".

Key vocabulary: 

  • dot plot
  • interquartile range
  • mean
  • mean absolute deviation
  • median
  • mode
  • range

Special materials needed:

  • paper
  • pencil
