Multiply, abstract

Multiply one-digit numbers. Practice until all one-digit multiplication facts have been memorized. There are many tricks that can be used to help along the way. One way to multiply by 4 is to double twice. One way to multiply by 8 is to double three times. In addition to the mental tricks, students will also learn two finger tricks. The first trick will help them multiply 1-10 by 9. The second trick will help them multiply 6-10 by 6-10. A good demo of the first trick can be found here, and a demo of the second is here. A good personal account of teaching multiplication to a struggling student can be found here. Next, have your students play multiplicative bingo, as seen here. In the video, he recommends students pass their game boards after making them, but I think this is a bad idea. If I were playing this game, I would certainly want to hold onto my board, and I assume others would feel similarly. Finally, lead this investigation.
