Mission Brief: The Efficiency Trap
Navigate your robot from Start to Finish . You MUST avoid the "Obstacle" squares. Bonus: Can you use a Loop (Repeat block) to make your code shorter?

Marty walks, dances, and wiggles!
We snap MartyBlocks together to move him.

What is a Block?
A block is an Instruction.
It tells the robot exactly what to do. One block = One action!
Roll Forward
Wait 1s
Turn Left

Main Blocks to Use:
Roll
Pick speed & time!

Equipment

The 30-Minute Blitz
00-05m
Mission Briefing
Explain the goal. Focus on Step-by-Step sequencing . One block equals one action on the mat.
05-25m
Active Lab Lab
Students plan on worksheets first (5m). This prevents "click-and-see" coding. Then code and test (15m).
25-30m
Extraction
Power down. Clean mat zones. Group sync: "What block was the hardest to time correctly?"
01 Pre-Mission Setup
The Lab Floor
Arrange mats in distinct zones. Sphero Minis need at least 4 feet of "clearance" to roll without hitting another team's bot.
Device Management
Bluetooth names are tricky. Label the physical bot (Mini 01) and the device with the same sticker. This saves 5 minutes of setup time.
Master Checklist
Robots charged (Sphero ~1hr, Marty ~1.5hr)
Sphero Edu & MartyBlocks apps installed
Mats taped to prevent "sliding" errors
02 Lab Troubleshooting
Marty blocks
! Wait Blocks: Without a "Wait" block between movements, Marty may try to do two things at once and trip.
! Leg Jams: If Marty makes a clicking sound, a leg is caught. Reset to neutral.
Sphero blocks
! Heading (Aim): The most common error. The blue tail MUST point at the student. Re-aim every time the robot is moved physically.
! Speed/Time: One square on the mat is usually 0.5s at 40 speed. Test and adjust!
03 Grade Level Focus
1st-2nd
Focus on Sequencing . "First I roll, then I wait, then I glow." Encourage 3-block codes. Use "Draw" mode first if blocks are too difficult.
3rd-4th
Introduce Loops and Turning . Challenge them to navigate a "U-Turn" on the 12-square mat using as few blocks as possible.
5th Grade
Focus on Variables & Logic . Can they make the robot go faster as it nears the finish line? Can they use a loop to spiral into the target?
