Third graders learn that computers take information IN (input) and send information OUT (output) — and practice telling input devices like the keyboard from output devices like the screen.
Students will be able to…
When you type on a keyboard, information goes INTO the computer. When the screen lights up, information comes OUT. What’s the difference between input and output?
Project this and sort each device into input (info goes IN) or output (info comes OUT).
Tap any phase to open the teacher moves and student actions.
