    I teach 5th grade and proportional reasoning is a big part of what we do, albeit very concretely. According to our standards, the shift from additive thinking to multiplicative thinking begins in 3rd grade. I once was in a PD where the facilitator explained that the shift couldn’t happen before 3rd grade, really, because children aren’t cognitively ready for it. She pointed to Piaget’s literature to support this.

    By 5th grade, it’s really obvious when a student is still thinking additively and not multiplicatively and it really holds kids back from some of the work we do. Sometimes I’m not entirely sure how to go back and take them through the shift, and I need to build my repertoire of experiences for early multiplicative thinking.
