Algebra is a major hurdle for math education yet is a significant gatekeeper for academic advancement. When solving algebra problems that elicit verbal reasoning about quantitative relations, children reliably use powerful invented proto-algebraic reasoning strategies that exhibit understanding of core algebraic concepts such as the notion of a variable and the inverse relations among arithmetic operations. Instruction that bridges on proto-algebraic strategies enhances algebra performance.
