Scratch Block Coding

👩‍🏫 Teacher’s Guide

Objective

Students will explain block coding (Scratch) as using visual blocks to build programs and identify basic blocks for motion, events, loops, and conditions.

Teaching Notes

• Show that blocks snap together to reduce typing errors.
• Connect blocks to concepts: events, loops, if/else, variables.
• Use a simple project: move sprite, say hello, repeat, bounce.
• Encourage planning: algorithm first, then blocks.

🧒 Student Worksheet

Concept and Helping Material

Scratch is a block-coding language where you drag and snap blocks together. Blocks represent instructions like moving, repeating, and checking conditions. Block coding helps beginners learn programming ideas without typing.

Computer Vocabulary and Definition

• — A block-based programming language for beginners.
• — A visual instruction you snap into a program.
• — A character or object in Scratch.
• — An action that starts code, like clicking a flag.
• — A set of blocks that runs together.

Computer Prtactices

• Plan a Scratch animation: Write 5 steps before building with blocks.
• Block hunt: Identify which blocks are events, motion, control, and looks.
• Mini project: Make a sprite move 10 steps, say hello, and bounce at edges.
• Debugging practice: Find a missing event block in a broken script (discussion).

Reflection
