The popular aid for the smallest pupils to learn to count. It helps practice addition.

The model has been printed, print settings verified. The print was then tested by kids and found by them to be fun!
Update note March-2024: The print profile was updated to improve printability and get cleaner texts on the front-side.

Learn by self-evaluation

It's fun when kids can learn on their own without the boring teacher correcting them all the time.
With the wrap-ups, the children evaluate themselves and can keep trying and training the task again and again on their own with no hassle.

How to assembly:

Easy. Print the one plate with all pieces. Stack the key-shaped pieces on the rivet. Thread a string through the hole in the rivet. Let the long end of the string hang from the back side. Secure the rivet by stuffing a larger knot or small bead into its head. You are ready to go.

How to use (for the kids):

You start winding from the starting notch.
Lead the string from the notch on the left to the correct answer on the right.

Then go under the plate and return the string back to the left side, take the next notch in the row. And so.
After you finish counting and winding, flip the plate around. 
The string should match the pattern on the backside.
And if the string does not match the pattern? No worry. Just unwind a bit and try again.
Unsure with the counting? Just try and check yourself. No red mark, no bad grade. Just fun.

How to print:

The design is purposely simple to make it very easy to print.
No fancy tricks needed. It's simple rookie's print job.
Any easy-to-print material will do (PLA, PETG or so…).

Enjoy ;)
