Hi Todd I visited Rumie website and attentievely studied the Initiative. Noble Initiative! Serious start! I think we have a possibility of cooperation. A+Click content is already on Android platform: https://play.google.com/store/search?q=aplusclick There are 12 free apps with about 5000 Math and Logic problems that work on Android devices. They are "ready to go in Math classes" of your initiative. Together, we can explore further move in areas beyond Math or translating A+Click content into other languages. All the Best Igor Kokcharov A+Click team
Thank you for extending your idea. In our case, we have thousands of different skills, not only one (for example, long division). We propose a simple multiple-choice solution for a large number of skills. Students can guess, but to score high, they need to think. The tool is for self-study for "self-motivated" kids. Certainly, there are multi-step math games, but for a small number of skills. Probably, you can find some of them at http://gws.ala.org/category/mathematics-computers Creating a specific game for each skill is a huge work.
However, I like the idea to transfer our simple multi-choice solution in problem-solving with several steps. It demands certain efforts. It is possible. Our advantage is a large base of existing meaningful problems.
