Prepare with the book. Teach with Logo Trail.

The handbook gives you the lesson behind the lesson. The online lecture keeps the problem open so students can predict, test, and explain what the turtle shows them.

For the teacher

The handbook prepares the lesson.

  • Know the idea before the first command is typed
  • Plan the pace and the questions that reveal it
  • Recognize useful mistakes and discuss what they show
  • Keep a complete sample solution for preparation

For students

The online lecture stages the discovery.

  • Predict what the turtle will do
  • Write, run, and revise a program
  • Read the drawing as evidence
  • Try an extension after the central idea is understood

Inside one module

See a lesson before it becomes a lecture.

Each chapter starts with the teaching intention, then gives you questions, likely turns in the discussion, and a finished program to study before class.

Teaching intention

Move & Turn

Help students treat the turtle as an object with both a position and a heading. A drawing records every move and turn they asked it to make.
