Discovering Multiplication

Multiplication can be a daunting concept for some students. But in my many years as a teacher I have learned that starting out with a discovery activity can help students to understand the process of multiplication and relieve some of the stress.

I like to start off with a real world problem such as “Jessie has 4 plates of cookies. There are 5 cookies on each plate. How many cookies does she have in all?” I have students work in groups or with partners and with counters or color tiles to solve the problem concretely.  I will walk around the room and discuss the methods used, and give a lot of praise for effort.

After working out the problem with the counters we will have a class discussion to recognize that there are many ways to solve the problem. Some students count, some skip count, some use repeated addition and some might already know a few multiplication tricks. I validate each method and move into the next phase, drawing pictures… Again I let students work in groups to find ways to draw pictures and then we share. After sharing I show the the way I like to make my pictures:

I continue this process with several more problems and then name multiplication as a way to solve problems with equal groups more quickly than adding.

We practice with picture problems as well and I reinforce vocabulary…

And, as with any skill, we practice, practice, practice!!!
