Eratosthenes: Geographer and Mathematician
Mathematicians can be famous, too! Introduce your class to Eratosthenes with a reading passage. After they complete the passage, learners respond to five questions, some of which require opinions and others reading comprehension skills.
Curated OER
Ancient Story Problems
Pupils research ancient civilizations, and develop story problems using symbols and coins from those times. They retell these story problems using modern terms and coins.
Curated OER
Coin Content
Pupils calculate ancient Greek coin values as compared to their weight, equivalence in grain, and determine their worth today. They explain how to calculate fractions of a given weight and how to use decimal numbers.

Discovering Math: Concepts in Algebra
Young scholars learn that speed is a function of time and distance, a quadratic equation can be used to figure out the path of fireworks, a photographer can use Algebra to figure out how many rolls he can afford if he needs twice as much...
Curated OER
Coin Content
Students calculate ancient Greek coin values as compared to their weight, and equivalence in grain. They then determine their worth today. They convert metric to U.S. customary weight systems.
