I use three methods: break apart, then traditional, then lattice. I usually teach one method per day, so they can practice it before getting a new method. After that, I let them decide which method to use on their daily work (whichever one is best for them).
When I do the first two methods, I use a multiplication cheer to help them know which numbers to multiply. It goes like this...
"Up and over"
(students raise right arm up, then diagonal to the left)
"Down with the zero"
(students squat down)
"Over and up"
(students raise left arm up, then diagonal to the right)
"Add, baby, add!"
(clap, clap, clap)
I'm attaching a colored mini-poster of the cheer that I made, and a student copy that they can keep and color. Feel free to share this!
When I teach lattice multiplication, the following website is very useful and kid-friendly. It teaches them step by step how to do it. http://www.coolmath4kids.com/times-t...ication-1.html
