Week 01 · Thursday: Sequencing (Code Crew G3)

Thursday: The Maze Run

"The pancakes are hot!" Rocket says. "I will zoom straight there." But a thick wall blocks his way.

Raven studies the maze. "What do you notice about the walls?" she asks.

Nova draws a glowing grid. "Each move is one step," she says. "Up, down, left, or right."

Let's plan Rocket's path one move at a time. Then we'll write clear directions to a kitchen sink.

Rocket is at S. The hot pancakes are at P. Write the sequence of moves to get there. Use U (up), D (down), L (left), R (right).

ROBOT PATH

Click cells in order to make a path from S to E. Diagonal moves not allowed. Walls are solid. Submit when you have a complete path.

Click S to start, then click each next cell. Path so far: 0 cells

WHY THIS EXERCISEProgramming a robot is exactly this: give it a SEQUENCE of moves. Each cell you click is one instruction. CSTA 1A-AP-10.

My moves:

Try Without Paper

Tell a parent the steps to walk from the front door to your bedroom.
Use only LEFT, RIGHT, FORWARD. No room names allowed!

READ THE MOVES

Rocket is at the start. He moves R, R, D. How many moves is that?

Which letter means go up?

Nova moves L, then R. Where does she end up?

Raven writes D, D, R. Rocket does R, D, D. Do they always reach the same square?

A friend has never been to your kitchen. Write 5 steps to get from the front door to the kitchen sink. Be clear, no skipping!
