An Algebraic Oversight
Tackle a common misconception using a performance task. Dividing by a variable to eliminate a variable may seem like a good idea, but simplifying the variable eliminates solutions as well. Learners develop algebraic and graphical support...
Curated OER
Solve algebraic proportions.
Students solve algebraic proportions. In this algebra lesson, students convert between fractions, percents and decimals. They solve problems using the distributive property.

Module 1: Functions and Their Inverses
Undo a function to create a new one. The inverse of a function does just that. An inquiry-based lesson examines the result of reversing the variables of a function, beginning with linear patterns and advancing to quadratic and...
Curated OER
Graphs and Data
Students investigate poverty using graphs. In this algebra lesson, students collect data on the effects of poverty and use different rules to analyze the data. They graph and use the trapezoid rule to interpret the data.

Step by Step
One step at a time! A seemingly linear relationship becomes an entirely new type of function. Young scholars build their understanding of step functions by completing a three-stage activity that incorporates multiple representations of...
Curated OER
Real Math
Students explore careers that require math knowledge and solve real life math problems. As a class, they compare and contrast classroom math to real life math and explore the links between algebra, geometry and math skills used in...
Curated OER
Academic Challenge
Students apply their knowledge of math to the real world. In this algebra instructional activity, students explore different way to incorporate math topics into the real world. They create a score or progress sheet to mark their progress.
Curated OER
The Binary Counter Circuit
Students count from 0-99 using the binary number system. In this algebra lesson, students problem solve by working with faulty circuits and applying their knowledge f Binary Numbers. They work in team to create a solution.

Understanding Zoning: Its use on the High Line in West Chelsea
Students are introduced to zoning. Evaluating information and reading a land-use map is enclosed in this lesson. List new development projects that they could propose for a given area.
Curated OER
Discovering Pi
Define terminology related to a circle. Practice accuracy in measuring and then create a spreadsheet based on data collected from solving for parts of a circle. Groups can have fun analyzing their data as it relates to Pi.
Curated OER
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
Area of Triangle using the Semi-Perimeter and Radius
Students investigate the properties of circles. For this geometry lesson, students calculate the area and perimeter of a triangle. They identify the perimeter and radius length of a circle.
Curated OER
Exploring Trigonometric Ratios
Young scholars calculate the different ratios using a right triangle. In this trigonometry lesson, students identify the sine, cosine and tangent of each side. They find the missing angles using the different ratios.
