Educate children about data in primary school

Understanding how it is taught. Interview with teachers. There is no formal plan, more used as a tool to explain other complex topics.
Use a lot of pictograms. Something you can directly count, tangible objects.
It's important to explain that there different possibilities how to represent the same data. They show them the journey from pictograms to bar charts
Pair of students. Just explore the intrractive tool.
Teachers were a bit hesitant, bc they were afraid that they won't be vebral, which is a key.
That means you can have different outcomes with the same app.
It's on Github, web-based.
The whole idea is that you can teach by going from familiar things to more complex and let people see the connection.
