In this presentation the importance of developing both fractional number understanding and algebraic reasoning will be articulated. I argue that arithmetical thinking about fractions necessarily involves multiplicative thinking as opposed to additive thinking. However in moving from arithmetical thinking to algebraic thinking involving fractions, a necessary intermediate stage for middle years’ students is effective representational and relational thinking of fractions. The aim is to identify the key stages and develop a Screening Test of algebraic readiness.
