Our children were playing coding games related to the subject of the project - the Solar System. The preschoolers could remember the names of the planets and they cooperated together. 

We played games using the robot Bee-bot. We programmed it to travel from planet to planet...

We also played with the robot Edison. We programmed it to read barcodes, so it will be able to avoid obstacles, follow a flashlight, spin, turn, drive forward and backwards, track a line etc.
