Ways Teams Build Software
Intro to Python Programming Grades 9–12 3-day lesson 26 deliverables Help students compare ways to build software and practice sharing Python work with a partner. Students choose methods that fit fictional projects and distinguish plans based on ordered steps from plans based on objects. They switch driver and navigator roles while writing and fixing code, then justify choices for a ticket app.

45-minute daysEvery day planned and timed
A short coding level practices 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 it with the lesson or as practice later.
Open the levelWhat does this lesson cover?
Group coding can leave a student watching silently while a partner does the work. This lesson gives each partner a clear role and requires them to switch and record what they notice.
The lab on Day 2 has an online version that uses CodeGrove, our in-browser code lab, in the Pair Up level. It practices writing and fixing three short programs as a pair: a club sign-up list, a snack vote count and a mile time check. Every online version comes with a paper version, so no internet is needed. CodeGrove is free, with no accounts or sign-ins.
Pair Up
Partners write and fix three programs and switch driver and navigator at every task, on paper or in CodeGrove.

Why teachers love this lesson
The project guides the team's methodStudents use project details to choose a development method and explain why it fits the work.
Partners switch roles and record feedbackThe driver works on the code while the navigator checks it, and students log what the navigator caught.
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 7 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 input() with int(), variables and f-strings.
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.
