This game is designed to help students understand / investigate how adding a piece of data, deleting (dropping) or changing a piece of data will affect the measures of central tendency. Students also see how just how much of an impact a low grade can have upon their overall grade.
It corresponds to the 2016 Virginia 6.11 (b) Standards of Learning.
2 decks of playing cards (grade cards / direction cards)
Student recording sheet
The activity works best with small groups of students, 2 to 4 students. Happy calculating!
