Plan It First
Intro to Python Programming Grades 9–12 3-day lesson 27 deliverables Teach students to turn clear plans into Python commands that guide a robot through rooms. Students write exact walking directions, draw flowcharts and use a partner's test to find steps that need work. They then write robot code and trace its path, checking how each move or turn changes what happens.

Short coding levels practice this lesson in CodeGrove, our code lab that runs in the browser. Students write the program, run it and check it, with no account and nothing to install. Use them with the lesson or as practice later.
See the levelsWhat does this lesson cover?
Students can rush into coding before they know what their program should do. This lesson connects written plans, flowcharts and robot paths, so you can see where their thinking goes wrong.
The lab on Day 2 and the activity on Day 3 have online versions that use CodeGrove, our in-browser code lab, in the First Steps level. It practices writing Python that drives a robot through rooms with move(), turn_left() and turn_right(), one command on each line. Every online version comes with a paper version, so no internet is needed. CodeGrove is free, with no accounts or sign-ins.
First Steps
Students write Python that drives a robot through five rooms and draw each path, on paper or in CodeGrove.

Why teachers love this lesson
A partner follows the plan exactlyStudents test walking directions with a classmate and fix steps that leave room for guessing.
Students draw what their code doesThey trace robot paths and mark where the robot stops, connecting each command to its result.
Print and digitalEvery page is a print-ready PDF, and the Google Forms™ and Google Slides™ let you teach the same lesson in Google Classroom™.
Real online activitiesStudents can use CodeGrove, our in-browser code lab, on a computer or tablet, and every online version has a paper version that works with no internet.
A key for every pageEvery day has its own answer key, and every written question has a sample answer and what to look for.
Every day fits a 45-minute classEach day's plan is timed activity by activity against real reading and writing speeds.

How do I get the files after I buy?
Instant download right after checkout: PowerPoint and Word files you can edit, print-ready PDFs, and links that copy the Google Forms™ and Google Slides™ into your Drive.
Can I buy the whole unit or course instead?
Yes. This lesson is part of the Unit 1 bundle and the complete Intro to Python Programming course. Both cost less than buying the lessons one at a time.
Is this AP Computer Science?
No. It is a full-year, non-AP intro to Python course for grades 9 to 12. For AP, see our AP Computer Science A and AP CSP courses.
What should students know before this lesson?
Students know that print() shows quoted text exactly and that an empty print() makes a blank line. They know that exact output counts, letter by letter.
What formats are the files in?
Every page is a print-ready PDF. The slides are an editable PowerPoint and the guided notes an editable Word file. The exit tickets and the quiz also come as Google Forms™, and the deck as Google Slides™.
Which standards does it cover?
Written for Florida's Foundations of Programming course (9007210). The skills map in the lesson shows which standards each day teaches.
