We’re using an iPad. It’s theoretically aimed at older children (5+) but my son was able to pick it up no problem.

I sat down with mine about 6 months ago (he was 3.75 at the time) and we learned what each of the blocks did and how to combine them.

Now he asks to make a program and can do it independently.

He experiments with the backgrounds, sound effects, loops and motion.

My son can read but knowing how to count/recognize numbers is more important in this interface. Everything is graphical. Loops require a number input.

Another toy aimed at older children that younger ones can play with is snap circuits. We introduced the toy at 3. He can copy the project schematic and build the project. He built the AM radio project independently.
