Kids at age 4 can start to program robot

Scratch Jr is designed for kids aged 5 and up and is basically restricted to the 2-D screen. If parents are eager to train their kids under age 5 with the critical sequencing logic concept, a necessity in coding, there are a lot of choices on the market. Children can learn coding by programming, e.g., a cute robot to tease or scare an unwitting family dog. However, these programming robotic kt still costs $200-400 and may not be affordable to a majority of families.    http://www.economist.com/news/science-and-technology/21660077-how-teach-computer-science-nursery-school-no-assembler-required
