I must seen about 10 videos before I came across this one. This one is my favorite. The other videos were to short and didn't really explain why you would / different fractions when using different thickness. The Illustrations and the little colored cubes helped me see the big picture. Nice job my friend!
Glad it was useful.. We post these videos to help our team and anyone else wanting to learn.. We're always looking to add resources to the library...got anything else that would help you out or want to learn?
