Explain the Change
Twelfth graders complete research relating to population changes in counties/states in the U.S. from 1900 to 2000 and use the slope formula to determine the overall change in population for each of the ten decades. They present their...
Curated OER
Step by Step
Students measure the rise and run of steps from a place that holds meaning for them. They write a reflection (in the form of a journal entry, poem, or short story) regarding this significant place.
