CROSS MULTIPLICATION

Grade 5 is when we begin to multiply 2 digit numbers by another 2 digit number. For example, 24 x 36 is a typical problem that the students might see. The Grade 6's will review this with the grade 5's and then they will move onto 3 digit by 2 digit and 4 digit by 1 digit problems. Students need a lot of practice in order to consistently be able to solve these types of problems. We go through several different methods of solving these types of problems, in order to give them an appreciation for a variety of methods. Today we watched a short video that explains this quiet well. I am including the video in the blog so kids can watch this at home with parents. I would encourage them to try a few of these types of problems every night till they master the process of cross multiplication.
