May is soon to be upon us, and my students are busy exploring multiplication strategies.
Below are just a few that often come up in our studies.
Standard Agorithm (and slight adaptations):
Halving and Doubling method:
Chisenbop Method: You can check it out online at: http://cs.iupui.edu/~aharris/chis/chis.html
Lattice Multiplication: Video http://www.youtube.com/watch?v=cijuPxHgZAA
Students are exploring many different methods of approach- not just the standard algorithm.
Merry Multiplying in May!
