Wow, you really made the best out of this situation using the minimal time you have available in the morning. It's very inspiring. My kids are usually tired after school and have homework, play dates and extracurricular activities which take up most of their time after school. A few minutes before school each day may be the best approach for us too, it will ensure that we have a set time everyday to do a few minutes of the type of math that will engage them. I will try it in the fall, thanks for sharing.
