Thanks to Alexandra Mayzler of Thinking Caps Turotirng for the following:

Because children who have ADHD are active learners incorporate math drills into activities. For example, create a scavenger hunt where each clue comes with a multiplication drill or play an outdoor game such as red light/green light and have the children calculate basic math facts. It is also important to break up the math review into shorter lessons 15-20 minutes of review but with more frequency. If students can spend 15 minutes playing a multiplication game every day of the week then they will be better able to grasp the material.
