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.

Answer key · Set A
Bo follows the flowchart
1The yes arrow The question is is it raining, and the answer is yes, so Bo follows the yes arrow to the raincoat box.
2True Both paths join before Bo walks to the bus, so the chart carries on from one box.
3no A yes or no question has two answers, so the diamond has a yes arrow and a no arrow.
43 On a sunny day Bo goes through look outside, put on the sunhat and walk to the bus, which is 3 boxes. The raincoat box is on the other path.
5False Actions go in boxes. A diamond asks a question.
6Bo takes the no arrow and wears the sunhat The answer to is it raining is no, so the same chart sends Bo down the no path. One chart works for both days.
71-D, 2-C, 3-A, 4-B Ovals start and end, boxes act, diamonds ask, and arrows show the way.
85, 2, 1, 4, 3 Bo starts, looks outside, answers the question, follows the yes arrow to the raincoat box, and then both paths meet at the bus.
9Put on a coat, Look outside Put on a coat and look outside are things to do, so they go in boxes. Is it sunny is a question, and End is an oval.
10A question goes in a diamond with a yes arrow and a no arrow A box means do something. A question needs a diamond, with a yes arrow and a no arrow.
11before Drawing first helps you spot mistakes while they are still easy to fix.
122 Each question gets its own diamond, so two questions need two diamonds.
