Designed for elementary readers, this course uses simple code blocks to introduce computational thinking and computer science basics. Students learn by connecting code blocks and apply constructs such as loops and conditional logic to create algorithms that solve problems. Space Cadet can be used online at or on an iPad using the Tynker app.

In Space Cadet, students help a crash-landed astronaut collect parts to repair their spaceship. As students complete each lesson, they are introduced to new concepts in a gentle progression. They first understand sequencing through a series of movement puzzles. Then they learn to recognize repeating patterns and apply loops to make their programs more efficient. Students explore events, actions, and conditional statements and apply these concepts to solve coding challenges. By the end of this course, students can solve puzzles with code, write algorithms using loops and conditionals, and debug simple programs.

Space Cadet maps directly to the elementary curriculum in Everyone Can Code program from Apple. Educators can download Apple Education’s free book Getting Started with Code 1 which provides additional guidance on how this course can be taught using an iPad.

Lesson Plan

Course: Space Cadet
Lesson 1: Crash Landed!
Time: 30+ mins


Welcome to the Space Cadet course! Students will begin their adventure in outer space, where they can choose which space cadet they want to play as: Mae or Buzz. As students complete the coding puzzles, they'll practice sequencing and collect items in space! Additionally, students will learn the following commands: "on start", "walk", and "jump".

New Code Blocks

  • : This is an event block that will run all code attached to it when students press the Play button. Note: Students must attach commands to an event block for their code to run.
  • : Make the character move one step forward.
  • : Make the character jump and land two spaces forward.


  • Code: The language that tells a device (e.g., computer, tablet, iPhone) what to do
  • Sequence: The order in which steps or events happen
  • Command: A specific action or instruction that tells a device (e.g., computer, tablet, iPhone) to do something.


Students will...
  • Sequence code blocks to create algorithms
  • Use code blocks to solve puzzles


  • iPads (with installed Tynker app), computers, or laptops

Warm-Up (5 minutes)

Remind students that a command is an action or instruction that tells the computer to do something. Next, ask students to pair up and think of real-world examples of commands when they brush their teeth. Bonus: Encourage teams to work together and create a sequence of commands to brush their teeth. Example:

Pick up your toothbrush
Wet the bristles of your toothbrush
Put toothpaste on the bristles
Brush your teeth for 2 minutes
Rinse your teeth and toothbrush

If this is your students' first time using Tynker, demonstrate how to...
  • Drag and drop Tynker code blocks to the center coding panel
  • Delete code blocks (drop the Tynker code blocks to the far left to make it disappear)
  • Attach code blocks

Activities (30 minutes)

Facilitate as students complete all Crash Landed! modules:
1. Select a Space Cadet (Puzzle)
  • Students will need to choose which space cadet they want to play as.
2. Introduction (Puzzle)
  • Students are introduced to the "walk" block, which makes the space cadet move one step forward.
  • Make sure students are connecting the "walk" code block to the "on start" block.
  • Do students need help running their code? Once students finish coding their program, ask them to press the play button.
3. Collect the Ray Gun (Puzzle)
  • To solve this coding puzzle, students will need to use multiple "walk" blocks.
  • Give a hint: Ask students to count out loud how many spaces the space cadet needs to move forward.
4. Collect the Tablet (Puzzle)
  • Now it's time to program the space cadet to walk forward and collect the tablet.
  • Give a hint: Ask students to count the number of spaces in front of the space cadet.
5. Jump the Rock (Puzzle)
  • Students need to reach the medkit, but there's a pile of rocks on the path.
  • To solve this coding puzzle, students need to use the "jump" block, which will make the space cadet jump and land two spaces forward.
  • Give a hint: Ask students to use the "jump" block to jump over the rock.
6. Beware of Aliens (Puzzle)
  • Students need to reach the powercell, but aliens are blocking the path.
  • To solve this coding puzzle, students need to use multiple "jump" blocks.
  • Give a hint: Tell students to avoid the aliens by jumping over them.
7. Avoid the Obstacles (Puzzle)
  • In this final coding puzzle, students need to use the correct sequence of "walk" and "jump" blocks to reach the crystal.
  • To solve this coding puzzle, students need to use multiple "jump" blocks.
  • Give a hint: Tell students to avoid the aliens by jumping over them.

Extended Activities (10 minutes)

Ask your students…
  • What are commands? (Answer: A specific action or instruction that tells a device to do something)
  • Who can give real-world examples of commands? (Answers will vary)
  • Which commands did you use in today's coding activities? (Answer: "jump" and "walk")

U.K. Standards

Key Stage 1
  • Use logical reasoning to predict the behaviour of simple programs
  • Use technology safely and respectfully, keeping personal information private; identify where to go for help and support when they have concerns about content or contact on the internet or other online technologies
Key Stage 2
  • Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; solve problems by decomposing them into smaller parts.
  • Use logical reasoning to explain how some simple algorithms work and to detect and correct errors in algorithms and programs.
  • Understand computer networks, including the internet; how they can provide multiple services, such as the World Wide Web, and the opportunities they offer for communication and collaboration.
  • Use technology safely, respectfully and responsibly; recognise acceptable/unacceptable behaviour; identify a range of ways to report concerns about content and contact.

Class Presentations

These student-facing slide presentations help educators seamlessly run Tynker lessons in a virtual or physical classroom setting. Each lesson has its own set of slides that introduce the big ideas, suggest unplugged activities, and include a section for each activity module. While running lesson slides, you can switch back and forth between the activity, the slides, answer keys and other lesson materials.
