What the work shows

The task

The teacher presented the students with a bucket containing two red balls and two blue balls. She asked them to determine the probability of getting two red balls if they randomly selected two balls from the bucket.

Images of student problem solving process

Iain's work shows that he is able to:

  • use a diagram to identify all possible outcomes
  • list all possible outcomes from a diagram or drawing.
