Surprisingly there aren't many products or worksheets out there that use the area/box method. Fortunately, for you and me my friend Diane from Fifth in the Middle has created such a product. My students loved the super hero theme of this product and the amount of space Diane provided for them to complete their work. This product covers 2 digit by 2 digit, 3 digit by 2 digit, and 3 digit by 3 digit.
As I mentioned before the box method allows students to understand that when multiplying 32 x 54 one is actually multiplying 30 x 50, not 3 x 5. With this understanding students are able to determine if their answer is reasonable.
If you haven't tried this method of multiplication I highly suggest you do, you will be surprised at the number of students who have success with this method rather than the standard algorithm.
Diane's Mighty Multiplication Box Method pack is available in the limited time Tricky Math Bundle currently on sale at Educents. You can grab the Tricky Math Bundle at Educents for $10.99!

The area model or box method is very powerful and a good model to return to as students are introduced to other kinds of multiplication like mixed number multiplication and multiplying binomials.
ReplyDeleteI will be trying this with my grade 4's at the end of the year when we review multiplication for sure - thanks!
ReplyDeleteThis seems like such a fabulous concept. I will make sure to pass it on to the intermediate teachers at my building.

I'm glad that it worked out so well for your class! It's definitely my preferred way of teaching multiplication!
ReplyDeleteI was just reading about this over at Diane's blog! This seems so much better than lattice. I didn't always like my kids using lattice because they wouldn't draw the lattice correctly and mess up. This seems so much better!
