This Ducklings assessment also includes:

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median. Individuals then determine the number that will not change the mean when added.

Instructional Ideas

  • Have class members share and explain how they determine the median and mean using the frequency table
  • Provide the class with a bar graph and ask them to determine the mean and median

  • A section guides teachers on the reflection of students' performance on the assessment
  • The rubric provides point values for different solutions

  • None
