Today I made bread with James and used only a half cup and a half teaspoon measure.
Not only does it review the concept that one-half and one-half equals a whole,
but he had to convert 4 1/2 cups of flour to 1/2 cups. If I had been baking with Quentin, I would have gotten out a cup measure for him to see that it held two half-cup measures of flour.
Later when it was time to preheat the oven, we looked at the temperature dial and talked about relative temperatures. He then set the dial to preheat the oven to 350 degrees Fahrenheit.
For older students, I could decide to increase or decrease a recipe to practice multiplying or dividing fractions. I could also have them use ratios and proportions.
