Ratio (Grade 6)




 


Videos and lessons to help Grade 6 students understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

Common Core: 6.RP.1

Suggested Learning Targets

  • I understand the what ratios are
  • I can solve problems involving ratios.
  • I can write ratio notation.
  • I can explain how order matters when writing a ratio.
  • I can demonstrate how ratios can be simplified.
  • I can demonstrate how ratios compare two quantities; the quantities do not have to be the same unit of measure.
  • I can recognize that ratios appear in a variety of different contexts; part-to-whole, part-to-part and rates.
  • I can generalize that all ratios relate two quantities or measures within a given situation in a multiplicative relationship.
  • I can analyze context to determine which kind of ratio is represented.
