Another Mental Subtraction Method
This free math video shows another way to do mental subtraction. Basically, in subtraction problems you can add or subtract the same amount to both numbers without changing the difference. Cuisenaire Rods prove this to be true in a visual and kinesthetic way. It is always best to show children (and adults) WHY a rule works instead of just telling them the rule.
Introduction to Ratios
Cuisenaire Rods provide a concrete way to talk about the concept of ratios. The “I get, you get” idea comes from Crewton Ramone’s House of Math – lots of great ideas there!
Using manipulatives to teach complex math concepts will bring a wider range of children to understanding than the traditional formula-driven way of teaching. Children with visual and kinesthetic learning styles will especially benefit from this style of instruction.
