A puzzle-based introduction to coding concepts for beginners where they learn sequencing, pattern recognition, loops, and conditional logic.

## Programming 1A Lesson Plan

### Introduction

In this lesson, students use conditional loops and path detection to help a spaceship stay on the course.

### Tynker Blocks Introduced

• : Make the Actor repeat this loop while the condition is true.

### Vocabulary

• No new terms are introduced in this lesson.

### Objectives

Students will...

• Evaluate when to use "repeat while" and "repeat until" code blocks
• Apply conditional logic and loops to solve puzzles

### Warm-Up (20 minutes)

1. Inform students that we are going to use a combination of loops and conditions in today's coding adventure. Can anyone remind the class what a repeat loop does? (repeats an action over and over)
2. Write the following on the classroom board:
• Walk forward until I reach an obstacle.
• While there is no obstacle in front of me, I will continue to walk forward.
3. Act out the two statements. As a class, identify if the statement is an example of a "repeat while" or a "repeat until" loop.
4. Who can identify what action keeps repeating over and over in the two statements? (answer: walking forward).
5. Ask, "What needs to happen to stop me from walking forward?" (answer: need to reach an obstacle).
6. Encourage students to work with a partner and think of another example of a "repeat while" loop and a "repeat until" loop. Discuss.

### Activities (40 minutes)

#### 1. Conditional Loop (Puzzle)

• Students can solve this puzzle by placing only "forward" blocks, but encourage them to use the "repeat until" conditional loop.
• Give a hint: Tell students to attach one "repeat until" block below the "when touched" block.

#### 2. Detect a Path (Puzzle)

• This puzzle introduces the "repeat while" code block, which tells the spaceship to repeat a set of commands (move forward) while a condition is detected (path in front).
• Students can solve this puzzle by placing only "forward" blocks, but encourage them to use the "repeat while" conditional loop.
• Give a hint: Tell students to attach one "repeat while" block below the "when touched" block.

#### 3. Turn to the Left (Puzzle)

• This puzzle uses the "if" block inside a "repeat until" loop.
• Remind students of today's warm-up activity. Say, "The spaceship needs instructions that tell it to react to the path turning left, and we can do that by using the 'if' and 'turn left' code blocks."
• Give a hint: Tell students to attach one "repeat until" block below the "when touched" block.

#### 4. Turn to the Right (Puzzle)

• This puzzle is similar to the previous one, but in the other direction; the spaceship turns right rather than left.
• Give a hint: Tell students to attach one "repeat until" block below the "when touched" block.

#### 5. Left Spiral (Puzzle)

• This puzzle gives students the option to use either "repeat while" or "repeat until." If students find one solution, challenge them to create a different solution.
• Give a hint: Tell students to attach one "repeat until" block below the "when touched" block

#### 6. Right Spiral (Puzzle)

• This puzzle is similar to the previous one, but in the opposite direction; the path and spaceship turn right rather than left.
• Give a hint: Tell students to attach one "repeat until" block below the "when touched" block.

### Optional Activities (25 minutes)

Same Code, Different Paths:

Notice the "Answer Key" solutions in Modules 3 and 5 use the same code, even though the paths are different!

1. Use the "Answer Key" solution to solve "Module 3: Turn to the Left."
2. Display the solution on the classroom board.
3. Open "Module 5: Left Spiral." Ask, "Do you think it's possible to solve this puzzle using the same code we used in our last puzzle (Module 3)?" Discuss.<
4. Use the same code from Module 3 to solve Module 5. Ask, "How is this possible?" Discuss.

### 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.
