A Plea for Pure Mathematics
Students explore the concept of GCD and LCM. In this GCD and LCM activity, students use a CAS program on their graphing calculator to determine the LCD and GCD of polynomials and large numbers. Students use the GCD function to determine the GCD of various fractions such as 3/4 and 17/3.
Intro Algebra: Graphing Data and the Coordinate Plane
Students bounce various tennis and racket balls, predicting and recording how fast they can bounce and catch them. They graph the results on a coordinate plane. And then, they compare their graphs with one another, analyzing how different variables affected their results. Finally, students identify how temperature can change the elasticity of materials.
Onwards and Upwards
High schoolers analyze a graph representing college tuition increases, consider the possible causes and consequences of these tuition increases and collect data on tuition changes at colleges in the United States by region and graph the data.
Here Comes The… Bill
Students share opinions about importance of milestone events they might host or attend. They then prepare estimated budgets for parties based on established budget totals, and compare their estimates against the real costs.
A Weighty Task
Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.
U-G-L-Y? I've Got a Great Alibi
Students create a survey to explore people's perception of beauty. In this biology lesson, students explain how an animal's appearance helps it survive. They analyze survey results and present findings in class.
Planning a Playground
Students explore the concept of building a playground. In this building a playground lesson plan, students find the maximum area given set parameters. Students build the playground so that all the equipment fits. Students work in groups to find the biggest area that fits all the equipment.
Exploring the Laws of Sines and Cosines
This lesson uses GeoGebra on the Web, or Geometer's Sketchpad to investigate and identify the different properties of sines and cosines. The class learns how the laws of sine and cosine relates to a right triangle and a non-right triangle. They practice using the Pythagorean Theorem to help identify the different ratios of the triangle.
Do You Feel Lucky?
Students calculate simple probabilities using mathematics then roll dice to test their predictions.
The Power of Algebra
First graders explore patterns. They look for patterns in number problems and use algebra as a means of solving general problems. Students devise a strategy to solve the number problem.
Running of the Bulls
Students examine what might be in store for Wall Street following the NASDAQ's 547.57 point plunge on Tuesday, April 4, 2000. They evaluate how they might manage a heavily laden high-tech portfolio before deciding how to invest in the market.
Students explore the mathematical probabilities involved in gambling and how these factors affect people's behavior. They work in pairs and conduct and experiment pertaining to blackjack. The class creates a graph showing the trends found.
Play to Learn
Students design a new playground environment after reading an article from The New York Times. Students incorporate math into the playground design by using precise measurements and prepare a scale drawing with key.
All About Aid
Begin this activity by estimating the cost of a college education and comparing it to actual data. After reading an article, high school seniors discuss the processes of the college loan corporations. They listen to a lecture about how to wade through all of the information and work together to create a brochure to help other students.
Difference of Equations
In this difference of equations worksheet, students solve and complete 49 various types of problems. First, they obtain the solution of any linear homogeneous second order difference equation. Then, students apply the method of solution to contextual problems. In addition, they use generating functions to solve non-homogeneous equations.
It's About Time!
Students examine the potentials, both positive and negative, of adapting an international 'Internet time' system. They create and solve word problems that require them to translate between the current time system and Internet time.
Students perform an experiment to test the value of technology to mathematics, and practice using the scientific method. They write lab reports in which they summarize their findings and evaluate their methods.
Students match scenarios with the terminology related to stock market fluctuations. They read an article, answer discussion questions, create a terminology poster, and write an essay.
Students explore how locations around a meteorite provide information about the meteorite's orbit. They explore triangulation techniques and create imaginary cities in which meteorites are ensconced.
The Shapes of Our World
Students utilize shapes and spatial relationships in a practical context by creating maps and writing a critical essay.
