Picking Pythagoras
Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...
Curated OER
Length, Perimeter and Area
Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship
Curated OER
Relative Ratios
Students discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.
Curated OER
Graphing
Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.
Curated OER
Money situations
In this money situations worksheet, high schoolers read money word problems and then list the benefit, opportunity cost, risks, and responsibilities for each one. Students do this for 6 questions.

Will the Leaning Tower Fall?
High schoolers research the Tower of Pisa and write a report about its history. They examine the physics of why it leans and whether it might fall. Students plan a trip to Italy to view the Tower. They develop an itinerary and budget for...
Curated OER
Off to College
High schoolers investigate linear, quadratic and exponential equations using the TI calculator. They identify relation and functions using ordered pairs, graph the data, analyze the data, and relate it to real-world situations.
