of the number sense standard for preschool and kindergarten in his state.
He showed little sustained interest in math materials. His teaching team
discussed their concerns and decided they needed to embed mathematical
curriculum in the areas where Ian typically played rather than continu-

type of play emerging. Children started sorting the food into categories.
