After introducing multiplication as equal groupings and skip counting, I introduce the Magical Minds to arrays with this fun video created by Mr. Salsich and his third graders.
While the video plays I ask the kids to predict how the kids will arrange the chairs for the sloth's presentation. We start using mathematical language of rows and columns.
Afterwards, I open a SmartBoard file asking the kids to arrange chairs for our classroom mascot, Kagunda the three-horned chameleon. And using their fingers to manipulate the pictures, the kids take turns creating different arrays. This is when I begin to introduce the language of factors and product.

Finally, when I can see that most students understand how to represent multiplication facts using arrays, I let them build their own arrays using anything they want from our classroom. This kinesthetic activity works as both a powerful assessment of their understanding as well as provides plenty of opportunity to address the needs of individuals.
