You might be asking why would I use video games in a kindergarten Spanish class. These games serve as one of my incentive options I utilize in our class.
Video games help with problem solving - understanding the value of trial and error when it comes to learning something new. They also help with hand-eye coordination and fine motor skills.
These are also the easiest kind of games students can learn to make themselves later on in elementary or middle school, and my hope is that they look back at this time with a sense of nostalgia and a love of learning when they find themselves in a computer science class.
