Random Numbers

🟨🐱 Random Numbers in Scratch (practical)

🎯 What Are Random Numbers?

Scratch has a block that gives you a random number between and including two values. This is great for adding surprises, challenges, or variety to your projects.

You’ll find it in the Operators category (green):

random-6

It chooses a random whole number (integer) between the two numbers you set.

🧪 Try It!

Make a sprite go to a random spot:

random-1

Roll a dice:

random-7

Choose a random costume:

random-8

🎓 Top Tips

  • You can use random numbers for:

  • Random movement of enemies or fish 🐟

  • Chance events in games (like coins falling or powerups appearing)
  • Generating questions or puzzles
  • Making computer decisions in AI-like games

  • Visual effects, like twinkling stars ✨ or popping bubbles

  • The numbers don’t have to be positive — you can go from -100 to 100 if you like.

⚠️ Watch Out!

  • The numbers are whole numbers (integers), not decimals.
  • The result includes both ends — so pick random 1 to 6 could return 1 or 6.

🛠️ Challenges

  1. Make a sprite say a random number between 1 and 100.
  2. Use pick random in a repeat block to move randomly around the screen.
  3. Create a "fortune teller" that gives a random message when clicked.
  4. Build a dice game using random numbers and variables.
