Description
Concrete Foundations for Algebraic Operations provides a concrete, hands-on approach to :
• multiplying algebraic binomials to a produce quadratic equation AND
• factoring quadratic equations back to the algebraic binomial factors
Presentations follow the sequence recommended for math instruction by both Dr. Montessori and modern cognitive neuroscientists: concrete/sensorial experiences bridging to abstract formulaic approaches using mathematical reasoning. All of the lessons can be given with nothing more than Golden Beads and a box of bead bars.
For more foundational work in pre- and early-Algebra, including integer concepts/operations, order of operations, use of variables, Euclid’s Axioms, and solving linear equations, please see Concrete Foundations for Integers and Linear Algebra.
