I love the Professor Bunsen Teaches Math, educational video games, by Prodigy Factory. I have been teaching science for 25 years and I know this is a great video game series. In this modern world, students are always finding ways to play video games on their chromebooks. They love these games, but they do not teach any academics. Professor Bunsen Teaches Math actually teaches real, grade level math skills. These games are age appropriate, engaging, and challenging. The games are aligned to math standards and they provide players much needed math vocabulary, math drills, and math practice. There are several games to choose from at each grade level. Players have to advance through 36 levels of each game to advance a grade level. The graphics are amazing and vary throughout the levels and grades. This game will support homeschool parents as well as public school teachers. The cost is very reasonable and allows for 20 player profiles, that is 20 students. I highly recommend the educational product.
