Invented at MIT. Trusted in classrooms for over 45 years. Still inspiring young programmers.
Logo is the original programming language designed specifically for children. Developed at MIT when computers first entered classrooms, Logo introduced a groundbreaking approach to learning—inspiring students to explore, experiment, and create through code. Terrapin has been a leader in Logo education since the beginning, developing and supporting Terrapin Logo continuously since 1979.
Logo Is a Proven Coding Language for Children
Terrapin Logo provides a learning environment with no floor and no ceiling, making it ideal for both beginners and advanced students.
• Start coding immediately with intuitive turtle graphics • Grow into a full-featured programming language • Explore math, geometry, logic, and computational thinking • Encourage creativity, problem-solving, and independent learning
Terrapin Logo is available through flexible licensing options to meet a wide range of needs.
• Household Logo License >> Use on up to 4 devices >> Ideal for families, homeschoolers, and individual learners • School Logo Licenses >> Available for 30, 200, or 1,000 users >> Designed for classrooms, schools, and districts
Turtle Tuesdays is a weekly coding challenge designed to keep students engaged and practicing creatively, often featuring Logo, Pro-Bot, and InO-Bot.
• New challenges each Tuesday—on the resource page, Facebook and Instagram • Solutions posted the following week on the Turtle Tuesdays resource page • Scales easily for different ages and skill levels >> Younger learners can create simple designs >> Older students can explore more advanced projects • Supports experimentation with new Logo commands • Browse PDFs of past challenges and print them anytime for classroom use

Get a Headstart in Coding with Logo Blocks! It's Free!
Unleash your creativity with Logo Blocks, by simply dragging blocks of code together to develop programs! Three levels allow children of any age, even teens and adults, to explore basic coding concepts.
• Move and turn the turtle • Explore patterns and colors • Repeat designs • Play games that reinforce coding concepts
Kinderlogo builds early sequencing skills and computational thinking in a developmentally appropriate way. Try Kinderlogo free for 30 days.
• Beginner Mode: move and turn the turtle, create simple loops • Intermediate Mode: use more drawing commands, If/Then conditionals, random numbers, and procedures • Advanced Mode: build games, simulations and complex programs by handling keyboard and mouse events, creating global variables, and using recursion.
A Tutorial and Activity Cards provide guidance and ideas at each level, and additional topics offer Tips for Power Coders, Debugging Help, and a Gallery of user-submitted programs. Visit the Logo Blocks Resources page for more information.
