“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.


Turtle Tuesdays Challenges for May 2025

Birthday Fun!

Maybe your birthday isn’t in May, but you probably know someone who has a May birthday.

Let’s celebrate by creating some fun Logo games, food, and decorations!


Challenge No. 139 - May 27, 2025

for Logo and Kinderlogo users

Let’s bake a birthday cake! Can you create one with many tiers?

Maybe even put a cherry or other decoration on top!

Use TURTLETEXT to add a message.


Challenge No. 138 - May 20, 2025

for Logo users

Can you invent your own dart game for you and your friends to play?

First create a dartboard. Use TURTLETEXT if you want to add a point value for each ring.

Either use FORWARD with a number to estimate how far the turtle should move to get to the center.

Or, write a procedure that goes forward a random distance.

It’s up to you to write the rules for your game. Have fun!


Challenge No. 137 - May 13, 2025

for Logo users

Let’s teach the turtle how to juggle!

Juggling can be a fun birthday activity, with or without the turtle.

There are ready-made juggling shapes in Logo’s Toolbox.

Hover over each shape to see its name.

It’s up to you to set the shape, make the turtle bigger and add some timing.

Set the turtle’s shape with an instruction like this: SETSHAPE "|~HOME/TOOLBOX/JUGGLING/JUGGLE0.PNG|

for Logo and Kinderlogo (Level 4) users

Can you make some balloons like these?

Try writing a procedure that chooses a random color and a random position to draw each balloon.
