Fun Computer Lesson: Sending Safe Messages Through Pipes
Materials Needed
- Two cups or small containers
- A piece of string or yarn
- Paper and crayons
- Small toy animals or blocks
- Two boxes labeled “Send” and “Receive”
- Optional: a tablet or computer with an adult nearby
Learning Objectives
By the end of the lesson, the child will be able to:
- Explain that a message is something we send to another person or place.
- Show how a message can travel from a sender to a receiver.
- Use the words send, receive, wait, and safe.
- Follow a simple three-step safety rule: Ask, Check, Tell.
- Create and send a pretend message using pictures, sounds, or words.
Success Criteria
The child is successful when they can:
- Point to who is sending and who is receiving.
- Move a pretend message from one place to another.
- Wait for a message before saying, “I received it!”
- Tell an adult before using an unfamiliar computer message or button.
Introduction: A Message Adventure
Hook: Hold up a toy or picture and say, “How can this little message travel to a friend across the room?”
Invite the child to make a prediction. Say:
“Today we will learn how messages move. We will pretend to use a computer pipe. A computer pipe is not a drinking straw. It is a pathway that helps one computer part send a message to another computer part.”
Tell the child:
“We will learn about sending, receiving, waiting, and staying safe.”
Vocabulary With Actions
- Send: Push your hands away from your body.
- Receive: Hold your hands out like you are catching a ball.
- Wait: Put one finger to your lips and freeze.
- Safe: Make a pretend shield with your arms.
- Message: Pretend to hold a small note.
Body: I Do — The Adult Demonstrates
1. Make a Pretend Message
Draw a simple picture, such as a smiley face, star, or apple. Say:
“This picture is my message. I am the sender because I am sending it.”
Place the picture in the box labeled Send. Then move it slowly to the box labeled Receive.
Say:
“The message travels through our pretend pipe. Now the other box receives it.”
2. Model Waiting
Hold the message halfway between the boxes. Ask, “Has the message arrived yet?”
Help the child answer, “Not yet. We need to wait.” Move the message into the receiving box and say, “Now it has arrived!”
3. Model Safe Computer Behavior
Point to the optional computer or tablet and say:
“Sometimes a computer shows a message or asks us to press a button. If we do not know what it means, we stop and ask a trusted grown-up.”
Practice the safety rule:
- Ask: “What is this?”
- Check: Look with a trusted adult.
- Tell: Explain what appeared on the screen.
Body: We Do — Send Messages Together
Activity 1: Cup-and-String Message Pipe
Use two cups connected by string if available. An adult holds one cup and the child holds the other.
- The adult whispers or says a simple word, such as “cat.”
- The child listens at the other cup.
- Ask, “Who sent the message?” and “Who received the message?”
- Switch roles and repeat.
Quick check: Ask the child to show with their hands what “send” and “receive” mean.
Activity 2: Toy Message Delivery
Place a toy animal in the Send box and a matching toy home or basket in the Receive area.
Use a playful story:
“The bunny wants to send a hello to the bear. The hello travels through the pipe. The bear waits. Now the bear receives the hello!”
Invite the child to deliver several messages. Use questions such as:
- “What is the message?”
- “Who is sending it?”
- “Who is receiving it?”
- “Should we wait or is it ready?”
Body: You Do — Create Your Own Message
Let the child choose one option:
- Draw a picture message.
- Build a message with blocks.
- Make a sound message, such as a clap pattern.
- Choose a toy to represent the message.
Have the child:
- Choose a sender.
- Choose a receiver.
- Place the message in the Send box.
- Say, “Please wait for the message.”
- Move the message to the Receive box.
- Say, “I received the message!”
Optional Digital Connection
With an adult present, open a familiar child-friendly drawing or messaging activity. Do not use unfamiliar commands, links, or programs.
Ask the child to draw a picture and show it to the adult. Explain:
“This is a pretend computer message. We only use safe programs with a grown-up. If something surprising appears, we stop, check, and tell.”
Movement Game: Send, Receive, Wait
Call out one of the four words. The child performs the matching action:
- Send: Pretend to throw a soft message forward.
- Receive: Pretend to catch it.
- Wait: Freeze like a statue.
- Safe: Make a shield with both arms.
After several rounds, let the child call out the words while the adult performs the actions.
Formative Assessment
During the activities, check understanding by asking:
- “What does send mean?”
- “What does receive mean?”
- “What do we do while a message is traveling?”
- “Who can help us when a computer message looks confusing?”
Look for whether the child can:
- Use or demonstrate at least two vocabulary words.
- Identify the sender and receiver.
- Wait for the message to arrive.
- Choose to ask an adult when unsure.
Summative Assessment: Message Mission
Give the child this challenge:
“Send a message from the puppy to the kitten. Tell me what the message is, who sends it, who receives it, and what we do if the computer shows something we do not understand.”
Expected response:
- The child creates or chooses a message.
- The child identifies the puppy as the sender.
- The child identifies the kitten as the receiver.
- The child moves the message through the pretend pipe.
- The child says, “Ask a grown-up,” or demonstrates the Ask, Check, Tell rule.
Differentiation and Choice
For a Child Needing More Support
- Use only two words at first: send and receive.
- Use real objects rather than drawings.
- Offer sentence starters: “I send ___.” “I receive ___.”
- Demonstrate each step before asking the child to try.
For a Child Ready for More Challenge
- Ask the child to create a three-part message journey: sender, pipe, receiver.
- Have the child explain why waiting is important.
- Invite the child to invent a safe message-delivery story.
- Ask the child to sort examples into “safe to ask about” and “stop and tell an adult.”
Conclusion: Tell What We Learned
Review the lesson using the child’s drawing, toy, or message box.
Say:
“Today we learned that a message can travel from a sender to a receiver. Sometimes it needs a pathway, or pipe. We wait for it to arrive. When a computer shows something we do not understand, we Ask, Check, and Tell.”
Invite the child to complete these sentences:
- “A sender is someone who ___.”
- “A receiver is someone who ___.”
- “When I see something confusing on a computer, I ___.”
Real-World Connection
Point out examples of messages in daily life, such as a wave, a spoken greeting, a letter, a doorbell, or a text sent by a trusted adult. Remind the child:
“Messages can be fun, but computer messages should always be used safely with a trusted grown-up.”
Optional Follow-Up
During the week, play “Message of the Day.” The child chooses a picture or word, names the sender and receiver, and delivers it safely from one room to another.
