Teachers and teacher educators are actively exploring the ways to use Generative AI tools like ChatGPT-4 in elementary math education. In this paper, we compare teacher-written and AI-generated hints and strategies for solving fourth grade math word problems as part of an open online math tutor called Usable Math. When given the perspectives of a 10-year math teacher and four virtual coaches (Estella Explainer, Chef Math Bear, How-to Hound, and Visual Vicuna), ChatGPT-4 provides text-heavy, largely procedural problem solving strategies. Teacher-written hints offer more ways to differentiate learning for students through the use of shorter, more child-accessible language; visual and graphical images; animations and gifs; and growth mindset-building statements that affirm children’s effort and persistence in solving math word problems.
