Thanksgiving is coming, and every cook in America is about to do math. A recipe is really a set of measurements — and doubling one is real multiplication with real consequences.
When we cook, we measure to get things just right. Cooks use special tools with different sizes!
Small to big — teaspoon, tablespoon, cup!
Let’s talk
Which tool is the biggest? Which is the smallest?
Have you ever helped cook or bake something? What did you make?
If a recipe needs 2 cups of flour and you’re making it twice, how many cups do you need?
Reveal the answerHide the answer
You’d need 4 cups — because 2 + 2 = 4! Making a recipe twice means doubling every single ingredient.
Try it
Measuring hands! Make a tiny scoop with your fingers (teaspoon), a bigger scoop with your palm (tablespoon), and cup both hands together (a cup). Now show me each one when I call it out!
Here’s the recipe for cornbread that serves 6 people. Your job: figure out what happens when more people show up.
One recipe, four ingredients.
Let’s talk
You need to serve 12 people. What happens to every ingredient?
Now you need to serve 18. How much cornmeal and butter?
Trickier: you only need to serve 3. What happens to the 3 tablespoons of butter — and why is that harder to measure?
Reveal the answersHide the answers
For 12, double everything: 4 cups cornmeal, 2 cups milk, 6 tablespoons butter, 4 eggs. For 18, triple it: 6 cups cornmeal and 9 tablespoons butter. For 3, cut it in half — and the butter becomes 1½ tablespoons, which is why cooks need fractions. Halving 2 eggs is even trickier: real cooks beat one egg and use half of it!

Scale it for our class! Count how many students are here today. With a partner, figure out how many batches of this recipe you’d need to feed everyone — then calculate the cornmeal. Show your reasoning, not just the answer.
