Introduction to coding
An AR classroom game for Grade 5. Learners can aim with their hands at the camera or play by tapping the screen.
This set has 6 questions in an interactive multiple choice activity.

A look before you play
Sample questions
A few real prompts from the game to help you choose an activity for your class.
What is an algorithm?
- A clear sequence of steps to solve a problem
- A language used to write computer programs
- The name of a program that solves problems
Read the explanation
A clear sequence of steps for solving a problem or getting a job done.
What is a loop for?
- Choose what to do based on a condition
- Make the same task run many times
- Go back and fix wrongly written commands
Read the explanation
Repeating the same work many times without writing it out again.
How does a conditional work?
- Repeat the same commands for a set number of rounds
- Run every command at once
- Check a condition, then choose what to do
Read the explanation
It tests a condition and takes one branch or the other.
Before you play
Game teaching guide
What children will practise
Understand core programming ideas: algorithms, loops, conditionals, bugs and finding a bug by tracing step by step, and see that coding trains step-by-step thinking.
What's in the worksheet
6 questions, multiple choice with 3 options each - An algorithm is a clear sequence of steps to solve a problem (not a programming language) - A loop makes the same task run many times - A conditional checks a condition, then chooses what to do - A bug is a fault in the program - Finding a bug: trace step by step to where it first goes wrong
How to use it in class
Use in the first lesson of a coding unit, before opening Scratch or a block tool. 5-6 minutes. - Play as a class, then children write an algorithm for brushing their teeth - Extend question 5: read out steps with one mistake and have children find it - If many miss question 1, point out that an algorithm can be written in Thai, not only code - Play it linked to a class and the scores go into the class gradebook.
Common sticking points
- In question 1, choosing a programming language, since algorithm is always heard alongside computers - In questions 2 and 3, swapping loop and conditional, because the two questions reuse each other's descriptions as distractors - In question 5, choosing keep changing things until it works, which children really do
