Double or More

Add to list Go to activity
Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone? Once the group has decided how to alter the recipe, assign each pair an ingredient to increase and measure out. As learners figure out how to double, halve, or triple those amounts in order for the recipe to stay in proportion, they explore fractions, multiplication, and addition. Try this with food, a “recipe” for combining paints to yield certain colors, or a play dough recipe. [Activity is publicly available through a web crawler capture on Archive.org.]
