This free math tutoring video explains the three ways of thinking about subtraction (taking away, finding the difference, and whole/parts) and explains which one is best and why. I also talk briefly about why counting strategies are not as effective as visualization of quantities. There will be more on this topic in a later video.
Once again, Cuisenaire Rods come to the rescue and make everything easy. They are a treasure. If you don’t yet have some, go buy them!!!
This free math tutoring video shows a way to introduce even and odd numbers to preschoolers and kindergarteners (or any age!) using Cuisenaire Rods. The pattern is much easier to remember when you can see it in color pictures rather than abstract symbols. Right-brained, visual-spatial learners will find this a breath of fresh air compared to what they are used to in school!
