Programming 1A Lesson Plan

Lesson: Sequencing

Time: 60+ mins


Students review sequencing and loops as they help Gus the astronaut collect power cells.

Tynker Blocks Introduced

  • No new code blocks are introduced in this lesson.


  • Sequence: The order in which steps or events happen


Students will...

  • Identify and order steps to solve puzzles
  • Recognize patterns to create sequencing tasks
  • Solve puzzles using loops for repetition


  • Computers (1 per student) with student account access to

Warm-Up (25 minutes)

Model a simple everyday task, such as washing your hands with soap and water. As a class, identify and order the steps. Write the steps on the board. For example:

  1. Turn on the water faucet
  2. Get your hands wet
  3. Apply soap
  4. Rub your hands together for about 10 seconds
  5. Rinse the soap off by placing your hands under the running water
  6. Turn off the water faucet

Explain to students that a sequence is the order in which things happen.

  • Ask, "Who can tell me the steps to clean your hands with hand sanitizer?" List the students' steps and follow them in order. Now complete the steps out of order. As a class, discuss the importance of completing steps in the right order.
  • Explain that identifying and sequencing steps is how we tell a computer what to do, but it is also necessary to give the computer instructions in the right order.

Activities (30 minutes)

1. Introduction (Introduction)

  • This short clip introduces Gus the astronaut, who has a crash landing on a strange planet.

2. Collect the Ray Gun (Puzzle)

  • Students will use the "walk" block to help Gus reach the ray gun.

3. Collect the Tablet (Puzzle)

  • Students will have more practice using the "walk" code block to help Gus reach the tablet.

4. Avoid Obstacles (Puzzle)

  • This puzzle uses the "jump" block, which was introduced in previous lessons with Codey the Troll. Say, "Instead of Codey jumping over bottle caps or thimbles, Gus jumps over rocks and aliens."
  • Remind students that the "jump" block makes the Actor jump over the obstacle and land on the other side.

5. Use a Loop (Puzzle)

  • This puzzle uses the "repeat" code block, which was introduced in previous lessons with Codey the Troll.
  • Students can solve this puzzle by placing the "walk" block nine times, but encourage them to use the "repeat" block.

6. More Obstacles (Puzzle)

  • Students can solve this puzzle by placing the "walk" and "jump" blocks three times, but encourage them to use the "repeat" block.
  • Give a hint: Tell students that two code blocks need to go inside the "repeat" block.

Optional Activities (25 minutes each)

Space Race:

  • Tell students they will be racing to complete the Sequencing puzzle modules as fast as possible!
  • Encourage students to work individually and keep going until they finish all Sequencing puzzle modules.
  • Tell students to raise their hand to let you know they are done.
  • As the first three students finish, write their names. The friendly competition ends once three students are done. Have the top three students compete against each other as the class cheers them on.
  • Hold a similar competition, but this time assign teams of two. See which teams can complete the Sequencing puzzle modules the fastest. As the first three teams finish, write their names. The friendly competition ends once three teams are done.

Sequencing Practice:

  1. As a class, brainstorm simple everyday tasks. For example: putting on a shoe, brushing your teeth, drinking water.
  2. Tell them to select an everyday task from the list and order the steps for that task.
  3. Discuss your students' sequencing lists and expected outcomes.

U.K. Standards

Key stage 1

Pupils should be taught to:

  • understand what algorithms are, how they are implemented as programs on digital devices, and that programs execute by following precise and unambiguous instructions
  • create and debug simple programs
  • use logical reasoning to predict the behaviour of simple programs
  • use technology purposefully to create, organise, store, manipulate and retrieve digital content
  • 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

Pupils should be taught to:

  • 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.
