01 · LEARNING TARGETS

  • Console.Log()Understand what it means, where it is used and practise it in a small example.
  • StatementsUnderstand what it means, where it is used and practise it in a small example.
  • Browser Dev ToolsUnderstand what it means, where it is used and practise it in a small example.
02 · TEACHING NOTES

Core lesson

Start with the idea, not the syntax. Understand JavaScript’s role, connect script-v3.js and use the console for output and debugging. The instructor should connect the topic to something students already understand, then introduce the exact terms they need for today.

Build in small steps. The teacher demonstrates one clean pattern, then students recreate it with their own content and styling so they understand the structure rather than copying blindly. Pause after each important change and ask students to predict what will happen before running or refreshing the result.

Develop good habits. Students should keep the browser and code editor open side-by-side, save often and refresh after each small change. Keep naming, indentation/structure and output clear enough that another student could follow the work.

03 · LIVE BUILD

Run console messages and simple expressions from an external script.

1

Plan the result first: decide what the user/student should see or be able to do at the end.

2

Build the smallest working version using today’s main concepts and test it immediately.

3

Add one improvement at a time and ask students to explain why each line/element is needed.

4

Test with at least two different inputs, screen sizes or scenarios and fix one issue together.

04 · STUDENT CHALLENGE

Independent practice

Print a short profile and three calculations to the console.

Teacher rule: give hints in steps, but avoid typing the complete answer for the student. The goal is to make them think, try and correct.
05 · END-OF-DAY CHECK

Before moving to the next day

  • I can explain script tag in simple words.
  • I can explain console.log() in simple words.
  • I can explain statements in simple words.
  • I can complete today’s mini task with only small hints.
Optional 10–15 minute home practice

Rebuild today’s example once without looking at the finished version. Change the names, values, text or design so the result is clearly your own.
