Double it, halve it, or cook for a crowd — grow each ingredient bar to its correctly scaled amount and keep the recipe in proportion.
A recipe card shows each ingredient as a bar, and the child scales the whole recipe up or down — doubling, halving, or cooking for more people — by growing each ingredient to its proportional amount. Scaling every ingredient by the same factor makes ratio and proportional reasoning concrete. Best for Grades 4–6.
