Buying My First Car
Students pretend they are about to buy their first new car. They must do all the calculations necessary to estimate the cost of purchasing the car. They see that the math they learn in school really does have real-life applications.
Curated OER
Flow Rates of Faucets and Rivers
Students work together to discover the flow rates of faucets and rivers. They relate their results to engineering and applied science concepts. They make predictions on the flow rate of a nearby river in their local community.
