Algorithmic Thinking Without a Computer – 8 Unplugged Activities, Grades 2–5

An algorithm is a precise step-by-step procedure, and children already know it from everyday life. This pack teaches the foundations of computational thinking without a single computer: all you need is paper, pencils, cards and chalk.

8 ready-to-teach unplugged activities:

• Robot and Programmer: students "program" a classmate with precise commands,
• Loops: how repetition makes a long program short,
• Conditions: if – then – else,
• Debugging: finding the mistake in a program,
• Sorting cards,
• Binary numbers: writing numbers with only ones and zeros,
• Pixels: how a picture is turned into numbers,
• How it all connects to real computers and block-based coding.

Every activity has a goal, timing, materials and step-by-step instructions, plus variations for stronger and weaker students. Use them one at a time or as a complete unit.

What you get (ZIP):

• an illustrated activity book (PDF, clickable table of contents),
• the same text in Word for editing,
• a worksheet with 12 tasks and an answer key,
• a lesson plan,
• a 16-slide presentation,
• an interactive quiz (10 questions) and flashcards in the browser that can read aloud – great for early readers.
