This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Graphing all kinds of situations in one and two variables is the focus of this detailed unit of daily lessons, teaching notes, and assessments. Learners start with piece-wise functions and work their way through setting up and solving...

Teams learn about the size of a nanometer by measuring objects and converting those measurements. A learning exercise then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

It was the single bloodiest day in Civil War history. Now, class members have the opportunity to walk in the footsteps of soldiers who fought in the Battle of Antietam using an interactive website. Supplemental resources include...

This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives...
