It is easy for us to see and appreciate differences in our children's physical development, but we forget that each child's brain also develops at a unique pace as well. That means a concept might be very hard for a child to grasp at one age, whereas 2 or 3 years later the same child will get the concept quickly without effort. Math on the Level lets a parent set aside a concept when the child is struggling and come back to it later when you feel the child is able to understand more easily.
Most approaches to math present only one way for concepts to be learned. Often they have grade-level required skills and a required list of concepts that must be covered by a certain age. Math on the Level operates differently. The teaching guides give directions for teaching every concept the child will learn before Algebra, but no concept has an age or grade level assigned. There is a suggested sequence to help you get started, but you are encouraged to teach concepts in whatever sequence makes sense for your child. The complete record keeping system helps you plan and keep track of everything each child has learned in math as well as what each child still needs to be taught.
Here is an example: If working on long division and your child is still struggling, despite using different manipulatives and other creative approaches, you can put long division aside for a while and move to another concept such as calculating area in Geometry & Measurements or rounding and estimating in Money and Decimals. Your child will continue to make progress in math as you avoid stress and tension from trying to teach when the child does not find understanding a concept to be easy.
