Textbooks (printouts) and parts used at the Human Academy programming school from 2020 to 2022. My child used them from 3rd to 6th grade. They didn't complete the Primary Course and went on to the Basic Course, and then they stopped after completing the Middle Course, so there are fewer Primary Course textbooks. There are many small parts, and I counted them. Most were there, but some quantities were reduced or increased (pictures 5 and 6). The textbooks have instructions, so you can make things by following them. Some textbooks have tears or names written on them. The bag had a name written on it, so I will send it with the name blacked out. If you like programming, the tools are all there, so I hope you will use them. Please feel free to message me if you have any questions.
