Shipping Routes - Dan Meyer Three Act Task

The questions are simple: As two ships leave port at the same time but at different speeds, we wonder if they will ever meet again? And if so, how long will that take? The lesson hooks students immediately with the initial video clip of two simulated ships leaving port and separating from one another as they travel at slower rates.

Capture-Recapture

Imagine that a city employee is given the task of counting the number of fish in a city pond in a park. The “capture-recapture” method may be used to approximate the number of fish in the pond. The employee could capture a number of fish, say 20, and tag them and release them back into the pond. Waiting until the fish have a chance to become mixed with the other fish in the pond, the employee can capture more fish. If the number of fish captured is 25 and 4 of them are tagged, we can use proportional reasoning to estimate the number of fish in the pond.

Preheating the Oven
