“So incredibly important to start our youngest learners on a path to coding literacy - this program is engaging and effective.” ~ Eileen H.

Welcome to Turtle Tuesdays!

Turtle Tuesdays offers fun programming challenges for Logo and (sometimes) Pro-Bot, InO-Bot, and Kinderlogo users. These challenges are also posted every Tuesday on Facebook and Instagram. All the challenges are archived here, with links and solutions in the sidebar. Easier designs await younger learners, while older students can tackle more difficult challenges. All students will enjoy creating code that makes their project special to them as they explore new commands. Encourage students to work collaboratively on projects.

If you don’t already have Logo, get the 14-day Free Trial and start coding!
Get an InO-Bot robot for free with a 3-year Logo Household License. Just $49.95 (plus S&H) for years of coding fun!
InO-Bot follows your Logo commands, just like the original floor turtle.


Turtle Tuesdays Challenges for March 2026

Introducing Logo Blocks!

All challenges can be done using either Logo or the new (free!) Logo Blocks coding environment.

Read more about Logo Blocks here, with tutorials and activities at each of 3 levels.

Go to Logo Blocks here: logoblocks.terrapinlogo.com

The Logo code in the Solutions is automatically created by the Logo Blocks.


Challenge No. 168 - March 17, 2026

For Logo and Logo Blocks (Intermediate Mode) users

This design uses multiple turtles to draw a repeated pattern using random colors.

In Logo, use CTURTLES to create multiple turtles in a circle. Logo Blocks has a block for that.

Can you create this design? (Sometimes the random color will be white!)

Can you think of a way to limit the colors by picking them at random from a list you create?


Challenge No. 167 - March 10, 2026

For Logo, Logo Blocks (Beginner Mode), Pro-Bot, and InO-Bot users

Challenge No. 166 - March 3, 2026
