Once everything is ready, it’s time to code your gratitude!

🦃 Part 1: Create Your Digital Thank-You Card in Scratch

Scratch is the perfect tool for kids aged 7–13 to start coding. It uses colorful drag-and-drop coding blocks, allowing children to focus on creativity instead of complex syntax.

Let’s build your animated, musical Thanksgiving card in seven fun steps.

🧩 Step 1: Start a New Project

1. Visit scratch.mit.edu/create.
2. Click Create → Rename your project as “ThankYouCard”.
3. Delete the default cat sprite (optional).

🎨 Step 2: Choose a Thanksgiving Background

1. Click on the Backdrop icon at the bottom-right corner.
2. Browse categories like Outdoors, Food, or Nature, or upload your own Thanksgiving image (like a dinner table or autumn forest).
3. This sets the stage for your card!

🦋 Step 3: Add a Character or Object Sprite

Your card will look more lively if you add characters. Try:

• 🦃 A turkey
  
• 🥧 A pumpkin pie
  
• 🧡 A heart
  
• 👧🏻👦🏻 A cartoon character holding a gift

You can upload your own image or draw one using the Scratch Paint Editor.

💬 Step 4: Display Your Message

Now it’s time to make your card “speak.”

Use the Looks blocks to display your thank-you message:

when green flag clicked

say "Happy Thanksgiving!" for 3 seconds

say "I'm thankful for you!" for 3 seconds

You can add multiple Say blocks for different parts of your message. To make it more dynamic, use Broadcast messages to coordinate text and animations.

Example:

when green flag clicked

broadcast [show message v]

Then add another sprite that says your next line when it receives the broadcast.

🎶 Step 5: Add Music and Sound Effects

Thanksgiving isn’t complete without joyful sounds! 🎵

1. Go to the Sounds tab.
2. Click Choose a Sound → Select a happy tune like Dance Celebrate or Jingle Bells.
3. Add this block:

when green flag clicked

play sound [Dance Celebrate v] until done

Now your card plays music when opened!

You can also add sound effects (like a turkey gobble or a whoosh when text appears).

🕹️ Step 6: Animate Your Sprites

Make your card feel alive by animating your sprites. Try these fun ideas:

Example 1: Make the Turkey Bounce

when green flag clicked

forever

  change y by 10

  wait 0.2 seconds

  change y by -10

  wait 0.2 seconds

end

Example 2: Make the Text Glow

Change text color using loops:

forever

  change color effect by 25

  wait 0.3 seconds

end

Example 3: Make the Pumpkin Spin

forever

  turn clockwise 15 degrees

  wait 0.2 seconds

end

The possibilities are endless—kids can experiment freely!

💡 Step 7: Add Interactivity

Make your card respond when someone clicks on it.

Example:

when this sprite clicked

say "Thank you for being amazing!" for 2 seconds

play sound [pop v]

Now your turkey “talks” when clicked! 🦃

You can even add variables like “click count” to track how many times the user interacts with your card.

🌈 Step 8: Share Your Digital Card

Once you’re happy with your design:

1. Click the Share button on Scratch.
2. Copy your project link.
3. Send it to family, friends, or teachers as your Digital Thanksgiving Card!

You can even embed it in an email or Google Classroom post.

💡 Pro Tip: Go Beyond Text and Animation

Here are some fun add-ons to make your Scratch card unforgettable:

• 🍁 Falling Leaves Effect: Use random motion and “clone” blocks to make autumn leaves fall.
• 💡 Light Flicker Effect: Alternate background brightness using color effects.
• 🎁 Surprise Button: Add a sprite that reveals a hidden message when clicked.
• 💬 Text-to-Speech Extension: Have your card speak the thank-you message aloud!

These advanced features take your card from simple to spectacular.

📱 Part 2: Build a Digital Thank-You Card in MIT App Inventor

If your child is a little older (Grades 6–10), MIT App Inventor is the perfect next step.
It’s a block-based tool that helps kids build real mobile apps — including interactive cards that run on Android phones.

Let’s make a Thanksgiving “Thank-You App” in six steps.

📲 Step 1: Start a New Project

1. Go to appinventor.mit.edu.
2. Click “Create Apps” and sign in with your Google account.
3. Select Start a new project → “ThankYouCardApp.”

You’ll see two main sections:

• Designer (for layout and visuals)
• Blocks (for programming logic)

🎨 Step 2: Design Your Card Layout

1. Add a Label:
   • Type “Happy Thanksgiving!”
   • Center it on the screen.
   • Change the font color to orange or red.
2. Add an Image:
   • Upload a turkey, heart, or pumpkin picture.
   • Resize and position it neatly.
3. Add a Button:
   • Set text to “Tap to Reveal Message.”
   • Make it stand out with a festive background color.
4. Optional:
   • Add a second Label (hidden at first) for your thank-you message.

🧠 Step 3: Add Music

Music adds warmth to your app!

1. Go to the Media section and drag a Player component.
2. Upload an MP3 file (a cheerful Thanksgiving tune).
3. Go to the Blocks section and add:

when Button1.Click do

  call Player1.Start

💬 Step 4: Add Interactivity

Make your hidden message appear after the button is clicked:

when Button1.Click do

  set Label2.Visible to true

  set Label2.Text to "Thank you for making my life brighter!"

Kids can personalize this message or even randomize it using lists:

set Label2.Text to select list item [Thank you, You’re the best, Happy Thanksgiving!] index random integer 1 to 3

Each tap reveals a new surprise! 🎁

🦋 Step 5: Add Simple Animation

To make your turkey move or bounce:

1. Drag a Canvas component onto the screen.
2. Add an ImageSprite (your turkey image).
3. Add this logic:

when Button1.Click do

  set ImageSprite1.X to ImageSprite1.X + 20

Each tap makes your sprite move to the right — it’s fun and interactive!

💡 Step 6: Add a Voice Message (Text to Speech)

Make your card talk using the TextToSpeech component!

when Button1.Click do

  call TextToSpeech1.Speak "Thank you and Happy Thanksgiving!"

Now your app literally says “thank you.” 🦃💬
