Message Pipes: Sending a Safe Computer Message

Materials Needed

• Two paper cups or clean cardboard tubes
• String, yarn, or a toy tunnel
• Three large letter cards: C, C, C
• Number cards from 1 to 15
• Small toy animals or blocks
• Paper and crayons
• Optional: a toy keyboard or pretend computer

Learning Objectives

By the end of the lesson, the child will be able to:

• Explain that a “pipe” can be a pretend path for sending a message.
• Send and receive a simple message using a toy pipe or tunnel.
• Recognize and say the letter C.
• Count objects from 1 to 15 with help as needed.
• State one computer-safety rule: “I ask a grown-up before using computer code.”

Success Criteria

I can:

• Put a message into the pretend pipe.
• Wait for and receive a message.
• Find three letter C cards.
• Count to 15.
• Tell a grown-up before trying unfamiliar computer activities.

Introduction: What Is a Message Pipe?

Teacher/parent says: “Today we will learn about a pretend message pipe. A message can travel from one place to another, just like a toy can travel through a tunnel.”

Show the child the cups, tube, or tunnel. Let the child look, touch, and explore the materials.

Safety note: “The computer words that inspired our game are grown-up computer code. We will not type or run them. We will play a safe pretend game instead.”

Hook: The Mystery Message

Put a toy animal in one cup or at one end of the tunnel.

Ask:

• “Where is the toy now?”
• “How could we send it to the other side?”
• “What might a message look like?”

Body

Part 1: I Do — Model Sending a Message

Place one letter card, such as C, beside the pretend pipe.

Teacher/parent says:

1. “First, I make a message.”
2. “My message is the letter C.”
3. “Next, I put the message into the pipe.”
4. “Now I wait.”
5. “I receive the message at the other end.”

Move the card through the tunnel or pass it through the cup-and-string telephone. Say, “Message received!”

Quick check: Ask, “What did I send?” Encourage the child to answer, “The letter C.”

Part 2: We Do — Send Three C Messages

Place three C cards on the table.

Invite the child to help:

1. Pick up one C card.
2. Say, “C is my message.”
3. Put the card into the pretend pipe.
4. Have the adult receive it.
5. Repeat with the other two cards.

Count together: “One C, two Cs, three Cs.”

Think-and-talk question: “Did the message stay the same or change?”

Part 3: We Do — Waiting for a Message

Explain that sometimes people wait for a message to arrive.

Place a toy animal at the receiving end. Count slowly from 1 to 5 while the child waits. Then send the toy through the tunnel.

Say:

• “We can wait calmly.”
• “We can listen for a message.”
• “We can say, ‘Message received!’ when it arrives.”

Quick check: Ask the child to show waiting hands and listening ears.

Part 4: You Do — Create and Send a Message

Let the child choose one message:

• A letter card
• A toy animal
• A block
• A drawing

The child sends the message through the pretend pipe while explaining the steps:

1. “I choose my message.”
2. “I send it.”
3. “I wait.”
4. “I receive it.”

Give specific feedback: “You remembered to wait before receiving the message.”

Part 5: Counting Challenge — Waiting Until 15

Explain that a computer may count or wait, but people should always use computer code safely with a trusted grown-up.

Have the child move a block into a line for each number while counting from 1 to 15. At 15, say, “Our pretend wait is finished!”

For a shorter activity, count from 1 to 5 first, then try counting to 10 or 15.

Part 6: Real-World Connection

Talk about places where messages travel:

• A letter travels in the mail.
• A voice travels through a telephone.
• A note travels from one person to another.
• A computer can send information to another computer.

Ask: “What message would you like to send to someone?”

The child may choose to send a greeting, a drawing, or a pretend message such as, “Have a happy day!”

Computer Safety Mini-Lesson

Use simple language:

• “Some computer words are for grown-ups.”
• “We do not type strange code without asking.”
• “We ask a trusted grown-up before clicking, typing, or running something new.”
• “We can learn about computers safely through pretend play.”

Have the child practice saying: “Ask first, then click.”

Assessment

Formative Assessment

During the lesson, observe whether the child can:

• Identify the pretend pipe or tunnel.
• Follow the send-wait-receive sequence.
• Recognize the letter C.
• Count at least five objects, working toward 15.
• Answer simple questions about where the message went.

Summative Demonstration

Ask the child to choose a message and demonstrate the entire process independently:

1. Choose a message.
2. Send it through the pretend pipe.
3. Wait quietly.
4. Receive the message.
5. Say one computer-safety rule.

Differentiation

For a Child Who Needs More Support

• Use only one letter card and count to 5.
• Provide hand-over-hand help with the tunnel.
• Use picture choices instead of spoken directions.
• Repeat the words “send,” “wait,” and “receive.”

For a Child Ready for More Challenge

• Create a two-part message, such as C plus a drawing.
• Take turns being the sender and receiver.
• Invent a pretend message rule, such as “Only red blocks may travel.”
• Count backward from 10 after sending a message.
• Draw a picture showing how a message travels.

Choice Activity

Let the child choose one:

• Build: Make a longer message tunnel with cushions or boxes.
• Draw: Draw a message traveling from one house to another.
• Act: Pretend to be a message traveling through a tunnel.
• Sort: Sort cards into “safe to play with a grown-up” and “ask before using.”

Conclusion: Tell What We Learned

Review the lesson with the child:

• “A pipe can be a pretend path for a message.”
• “A message can be sent, waited for, and received.”
• “We practiced the letter C and counting to 15.”
• “We ask a grown-up before using unfamiliar computer code.”

Finish with the child completing this sentence:

“Today I sent a message through a pipe. My message was ______.”

Optional Follow-Up

During the week, invite the child to send safe pretend messages using blocks, drawings, or stuffed animals. Each time, practice saying: “Send, wait, receive—and ask before using a computer.”
