Explanation
We have many tools for sending a message: a phone call, a text message, a video call, an email and a letter. Each tool is good for something. A phone call lets us hear a voice at once. A video call lets us see and hear someone who is far away. A text message is quick for a short note. An email suits a longer message, and a letter is something to keep. To choose a tool, we ask: Who is it for? How fast must it be? Can the person see, hear or read it? A friend who cannot see well may like a phone call or a voice message. We use these tools with a grown-up’s permission.
Worked examples
Marwan wants to ask a friend to play right now. A short message is quick, and his friend can answer at once.
Habiba wants to show her new puppy to Grandma, who lives in another country. A video call lets Grandma see and hear.
Class 2 asked: how would you invite a friend to play? Most children chose a message.
Class activity
Choose and count. With a grown-up, think of four situations, such as inviting a friend, thanking a relative far away, ordering a cake and telling a teacher you will be absent. For each, choose a tool and say your reason. Then ask eight people which tool they would use for one situation, and draw a dot for each answer.
