### Great Routines for Using Subtraction Mad Minutes

There are many different strategies that can help students learn to master their math facts. I have found that using the mad minute routine with my students regularly has been rewarding and faster than other systems that I have used. It is mostly because it is a competition-based strategy that students, for the most part, do not shy away from. This is because you are competing with an intangible inanimate thing, time or more exact the clock. I have in the past had students compete against the clock and one another. The winner would be the person who completed it correctly in the least amount of time. I find that this technique fizzles because some of the weaker students decide not to give their best effort. Focusing on pitting them against the clock takes the negative social connotations out of it and makes it more of a cooperative approach. If I have a very bright class, I will often start with thirty problems on each worksheet and then every few days repeat it with students but adding additional problems. About five years ago I had a class get to seventy-right problems, that was the entire group.

As far as an exact routine goes with Subtraction Mad Minutes, each teacher is best to approach this in a manner that best fits their class procedures. I found that it helpful to do either first thing or last thing each school day. However, you set up your routine make sure that it is consistent. Kids thrive on consistency. I would recommend that you do it the same time of day, each day. Use the same time device each time you do this. Some teachers prefer using fixed number sheets rather than mixed subtrahend sheets. In my experience both work fairly well. I used the fixed strategy early in my career, but for the last decade I have used the mixed number versions.
