Math
The 13‑year‑old measured flour, sugar, and butter using teaspoons and cups, converting between metric and imperial units while recording the quantities on a kitchen notebook. They calculated the total weight of the dough by adding fractional measurements and used ratios to adjust the recipe for a larger batch of cookies. While the oven timer counted down, they tracked the baking time in minutes and seconds, noting the percentage increase in volume as the cookies rose. Finally, they recorded the number of cookies produced and determined the average weight per cookie, applying concepts of division and averaging.
Tips
Tips: 1) Have the student design a new cookie recipe that doubles or halves the original, requiring them to recalculate all ingredient amounts using proportional reasoning. 2) Introduce a budgeting exercise where they price each ingredient, calculate total cost, and compare cost per cookie to practice division and decimals. 3) Create a graph of baking time versus cookie size, allowing them to interpret data trends and make predictions for future batches. 4) Use a kitchen thermometer to explore temperature conversions between Celsius and Fahrenheit, reinforcing unit conversion skills.
