Mina's chartOn school trip day Bo needed a raincoat if it rained and a sunhat if it was sunny. Mina drew a flowchart, a map of a program, with arrows that show which way to go. An oval means start or end, a box means do something, and a diamond asks a question and has a yes arrow and a no arrow. Her chart went Start, then a box, look outside, then a diamond, is it raining? Yes led to the raincoat box and no led to the sunhat box. Both paths met at one box, walk to the bus, and then came the end oval. Bo followed the chart like a trail on the floor. At the diamond he looked out of the window: drip, drip, rain! He took the yes arrow, put on the raincoat and marched to the bus.
