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.
