Personal Multiplication Strategies in my Grade Five Classroom


Lately our class has been studying multiplication and I have been amazed at how many different personal strategies these students already have. Their repertoire of multiplication methods is quite impressive. 

With parent permission I have been videotaping some of these strategies as my students are working through daily assignments.  I am showcasing a few of these today on my site.

The first video is a group of students pondering multiplying the facts 30 x 60.  It is a group discussion explaining how they found the answer to this equation. (Please be patient…it will load)

The second video clip is a student applying a personal strategy for multiplying by 3 x 900.  He calls this the Magic 9 method.

The third video clip is a student who is learning to check for reasonableness of her answer. (Please be patient…it will load)

The next few weeks, I am planning on continuing to showcase some of my students work via video clips.

My hope is that other teachers may see how students can collaboratively support each other as they work through questions and problems.  I also hope to showcase some of the different personal strategies my students are using as they are working through multiplication and other concepts of our “new” revised Alberta mathematics curriculum. 

To be continued….
