Questions / instructions:
Billy, Brent and Pip look at this chart to see if they can have a biscuit. They start at the box which says Start here. They read the question, then follow the yes or no arrow to find out what they can do. I want you to use the chart, and follow the arrows, to find out what Billy, Brent and Pip can do.

Commentary:
Students got confused between "no" or "yes" on the flow chart and the answer they were giving. For instance, for Billy they had to follow the "yes" arrow, but then answer "no."
