Think Like a Programmer

Split problems, trace code, backtrack, then type.

Topic sequence

Follow it in order. Each topic assumes the one before it.

01Break Problems ApartbeginnerClass 9 to 10Big tasks feel impossible until you split them into small steps. Each step should be clear enough to do or check.18 min 02Boxes for ValuesbeginnerClass 9 to 10Programs store numbers and words in named boxes called variables. Picture the box, read the label, watch the value change.16 min 03Trace a ProgrambeginnerClass 9 to 10animated labTracing means running code on paper: follow each line and write variable values in a table until the program stops.20 min 04Solve with BacktrackingbeginnerClass 9 to 10animated labTry a path forward. If you hit a dead end, go back to the last choice and try another option.20 min 05Test Small FirstbeginnerClass 9 to 10Try the tiniest example before the full homework. Two numbers before twenty. One maze corner before the whole map.15 min 06Plan Before CodebeginnerClass 9 to 10animated labTen minutes of planning saves an hour of confused typing. Use lists, sketches and trace tables before you open an editor.15 min
