The Ultimate Guide to Teaching Lattice Multiplication

It really amazes me how many teachers and inevitably students with years of experience that have never come across or taught lattice multiplication. Which is a brilliant alternative to traditional multiplication.

"What is Lattice Multiplication" you may ask?

Lattice multiplication offers a very simple alternative to traditional multiplication methods when dealing with whole numbers and decimals of any size.  I find it incredibly useful to use lattice multiplication with reluctant mathematician's who need to take a fresh look at solving both simple and complex equations.

I came across these two excellent slideshows that explain in simple terms for both teachers and students how to do lattice multiplication for whole numbers and decimals.  I would love to creadit the author who put them together but I cannot find any details.

Please share this with your kids and add this as another tool in your maths toolbox.
