Abstract
There are now strong arguments for building closer links between children’s understanding
of numbers and number operations and the beginning of algebraic (relational) thinking in
the primary school years. Rarely, however, do Australian mathematics textbooks give
enough guidance for teachers to use good activities in the classroom to promote algebraic
thinking. By contrast, Japanese mathematics textbooks introduce students to relational
thinking about number sentences, starting from the first grade. The idea of a learning
trajectory – or trajectories – seems a fruitful way of looking at how this is achieved and
what it might mean for the teaching of Number and algebra in the primary years.
