Use paper cards with dots (1, 2, 4, 8, 16) so kids can flip cards to make each letter number.
How to use it
- Act out the code first: one child is the robot, another reads the arrows.
- Tape a grid on the floor and walk the code.
- Start with a two-minute “I notice, I wonder” talk about the picture on the sheet.
Watch for
Mixing up the robot’s left and right when it faces down the page. Turn the paper to match.
Talk about it
- What is an algorithm you use every day?
- Where have you seen this outside of school?
