It is about teaching traditional topics in more profound ways. ref http www.earlyalgebra.terc.edu TERC ref It is also an area of research in mathematics education . Traditionally, algebra instruction has been postponed until adolescence. However, data of early algebra researchers shows ways to teach algebraic thinking much earlier. The National Council of Teachers of Mathematics NCTM integrates algebra into its Principles and Standards starting from Kindergarten. One of the major goals of early algebra is generalizing number and set ideas. It moves from particular numbers to patterns in numbers. This includes generalizing arithmetic operations as functions, as well as engaging children in noticing and beginning to formalize properties of numbers and operations such as the commutative property, identities, and inverses. Students historically have had a very difficult time adjusting to algebra for a number of reasons. Researchers ref Carpenter, T.P., Franke, M.L., and Levi, L. Thinking Mathematically.
