Plan a Route
Put everything together: read the map, spot obstacles and landmarks, count a short safe path, and test it in the route lab.
- Plan a full route from start to goal on a map with obstacles
- Write forwards and turns in order before running the plan
- Revise the route when a test run fails

Lesson 1 of 3
Start with the whole picture
Before any steps, study the map. Mark start facing, goal, walls, and one landmark you will pass. This thirty-second scan saves many bad runs.
Trace two candidate paths with your finger. Count steps on each. Pick the shorter safe route unless your teacher asks for the scenic one.
Open the map route lab. Enter or choose your steps, then play the journey. Watch each segment until you reach the goal or hit a blocker.
Route planner
Build a full route on the map, run it step by step, and revise until you reach the goal without hitting obstacles.
Plan a route
Follow landmarks past walls to treasureYou start at the bottom left. The treasure is top right. Walls block some squares.
Map ready
A map shows where you can go and what is in the way. Planning before moving saves steps.
Lesson 2 of 3
Write the final list
Translate the traced path into commands: forwards for straight legs, turns at corners, extra forwards after a landmark if needed.
Read the list aloud while your finger walks the map. If words and finger diverge, fix the list first.
When the lab run succeeds, copy the plan to your notebook. Successful routes are worth keeping as templates.
Lesson 3 of 3
Routes in the wild
Hikers use maps with landmarks and obstacle symbols. Bus apps show routes with turns at stations. You practised the same thinking on a small grid.
If you teach a family member your route game, let them be the human robot once. Teaching proves you understand the plan.
You now have tools for grids, maps, robots, and friends. Use them whenever a path looks confusing and you want a test before you walk.
Practice
Work these out yourself
No answer key here on purpose: these are the questions worth thinking through before you move on. Open one and work it out.
