Lesson 18: End of Course Project


This capstone lesson takes students through the process of designing, developing, and showcasing their own Play Lab projects! To ensure this process goes smoothly, we have provided a step-by-step structure for students to follow, from planning on paper to coding on our website. In addition, we offer ideas to help teachers facilitate a showcase finale!


This lesson provides students with space to create a project of their own design, using a step-by-step process that requires planning but also allows for broad creativity.

Students will be able to:

  • Use a planned design as a blueprint for creation.
  • Overcome obstacles such as time constraints or bugs.


  • Play through the puzzles to find any potential problem areas for your class.
  • Print out one Play Lab Project Planning Guide for each student (or pair).
  • Review the Play Lab Project Planning Guide (Exemplar) document.
  • (Optional) Complete your own planning guide and code your own project to show to students!


Heads Up! Please make a copy of any documents you plan to share with students.

Get students excited and ready for today's activity!


We have already had a chance to build a project in Play Lab. Today, this experience will be much more open-ended, so it will require planning beforehand! Planning is a very important part of coding a game or any other kind of software. So, before we jump onto computers, we will spend some time planning the projects we want to build.

Teaching Tip

If students are pair programming for this assignment, this warm up is a great opportunity for them to practice sharing and respecting others' ideas. Ensure students are following group work norms you already have in place in your classroom. Otherwise, spend a brief moment going over your expectations.

Distribute: Distribute one Play Lab Project Planning Guide to each student or pair. With students, go over the steps listed on the guide, then allow them to complete it. Refer to the included exemplar if needed.

Main Activity (25 min)


Teaching Tip

Students will experience plenty of trial and error while coding. Their projects are likely to become truncated versions of their original scope. Remind students that this kind of compromise is common in software design. It's okay if they don't get to build in every feature they planned!

Equipped with their completed planning guides, students are now ready to bring their projects to life. These levels correspond to the structure of the planning guide, and help navigate students through the process of transforming their ideas into code.

Wrap Up (10 min)


To celebrate students' work, spend the last 10 minutes or so allowing them to showcase their projects. This can be done in many ways, but here are a few:

  • Public Demo: Select a few exemplary volunteers to briefly demo their projects in front of the class. As they do so, have them touch on what the planning-to-coding experience was like for them, including ideas they'd still like to implement.
  • Pair Playtesting: Have students or groups pair up and playtest each other's projects. As they do, ask them to provide positive and constructive feedback to each other. The benefit here is that students will have the opportunity to provide and respond to feedback in a smaller setting.
  • Gallery Walk: Ensure all students have their projects ready for testing. Have students move "musical chairs"-style to another computer and playtest the project there for a few minutes, until they receive a signal from you to move to another computer. Repeat this every few minutes. While there is less opportunity for structured communication here, this ensures students get to demo as many of their peers' projects as possible.

It is amazing how much you have learned! Let's make a game step by step.

Using new blocks in your toolbox, choose a new background, then pick an actor to be in your game.

Student Instructions

Use blocks like events and actions to make your player move when you press the arrow keys.

Get the player to the targets to complete this puzzle.

Let's add some more characters to your game!

Use the set actor block to add more characters then move to the goal to complete this puzzle.

Student Instructions

Multiple characters and getting the actors moving is a great start to a game, but we need to do more to make this feel like a real game. Let's add a score!

Use event blocks like the when actor touches to change the score or win the game. Score 5 points or win the game to complete this puzzle.
