Scratch Pattern Recognition Activity

Welcome,Coders!

Your Mission:
Create a Scratch program that sorts shapes by color, just like how AI recognizes patterns!  Watch the two videos above. Then follow the steps below!

Step 2: Add Shapes

• Click the Choose a Sprite button (it looks like a cat face).

• Pick 2 or 3 different shapes (circle, square, triangle).

Step 3: Color Your Shapes

• Click each shape.

• Click the Costume tab (top left).

• Use the paint tools to change the color of each shape.

Step 4: Make Sorting Zones

• Click the Backdrops tab.

• Use the paint tools to draw two colored boxes on the Stage (for example, a red zone and a blue zone).

Step 5: Code the Sorting

For each shape, add these blocks:

• • when this sprite clicked

  • go to x: [zone x] y: [zone y]

• Tip: To find the coordinates, drag your shape to the zone and look at the x/y numbers below the Stage.

Step 6: Test Your Program

• Click each shape. Does it move to the correct colored zone?

Bonus Challenge!

Can you sort by both color and shape?

• • Add a third zone for a new color or shape.

  • Make your code move shapes to the right spot based on both their color and their shape!
