The Economics of Income: If You’re So Smart, Why Aren't You Rich?
If basketball players make more than teachers, why shouldn't learners all aspire to play in the NBA? Unraveling the cost and benefits of education and future economic success can be tricky. Economic data, real-life cases, and some...

Migration Mishaps
Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Carbon Footprint
Your young environmentalists can calculate their carbon footprint and discuss ways to reduce it with a worksheet about climate change. After reading a handout about what impact one's carbon footprint can have on the environment, kids...

Linear Inequalities
Ninth graders practice recognizing similarities and differences found in the graphing of inequalities and equations. Once observatioons are made they solve some of their own applying prior knowledge.

How Many More on a Graph?
First graders identify a number that is one more or one less than a number up to one hundred and identify a mystery number. They also create a class graph that illustrates how many children are in each family, and answer questions about...
Curated OER
Balanced Or Unbalanced
Pupils use physical models and graphs in order to solve problems that have their origin in the real world that require algebraic thinking. The words are changed into equations and inequalities in order to be solved. This requires...

Linear-Quadratic Inequalities
Students graph linear and quadratic functions. In this algebra lesson, students create graph with specific coordinate points. They use the Ti to visualise and differentiate between the two functions.
Curated OER
Introduction to Graphs
Students poll classmates to gather information for a graph. They identify three types of graphs (bar, line, table). Students create each type of graph using data gathered from classmates.
Curated OER
Stress, Strain and Hooke's Law
Students study Hooke's Law and stress-strain relationships. In this spring lesson students create a strain graph in Microsoft Excel.

Cockroach Slope
Learners identify the slope of linear functions. For this slope lesson, students collect data and graph it. They write equations with no more than two variables and use technology to explain their data.

Transformation Investigation
Graph it! Investigate transformations with a graphing calculator. Pupils graph sets of linear functions on the same set of axes. They determine how changes in the equation of a linear function result in changes in the graph.

Plotting Wind Speed and Altitude
Students construct, read and interpret tables, charts and graphs. They draw inferences and develop convincing arguments that are based on data analysis. They create a graph displaying altitude versus wind speed.
Curated OER
Functions of Algebra
Young scholars use technology graph and evaluate linear inequalities. They write and manipulate inequalities for use on a graphing calculator. In addition they apply their skills to analyze inequalities. Answer Key included.
Curated OER
Border Patrol
Young scholars investigate systems of linear inequalities as they apply to an area of land. They practice graphing systems and determine if a point lies in the solution.
