Students investigate data collection and analysis.  In this Algebra I lesson plan, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.

Students explore various approaches to solving a problem of maximizing the total production of apples in an orchard. For this apple orchard lesson, students collect data in order to solve the apple orchard problem presented. Students...

Students discuss the origin of strawberries and employees involved with picking strawberries. In this algebra lesson, students discuss how much a worker who picks strawberry makes based on their flats. They create a table with the...

Students identify real graphs and misleading graphs. In this algebra lesson, students surf the Internet for real life scenarios where graphs are used in a misleading way as well as in a correct way.

Students calculate ratio and proportion. In this unit rates lesson, students estimate using proportions and find their errors in doing so. They calculate unit rates and define the concept of unit rates.

Students compute surface area and volume of prisms. In this surface area lesson, students find the surface area and volume of rectangular and triangular prisms. Independently, students use their computers to determine the volume,...

Students explore proportional reasoning.  In this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.

Students investigate threee types of maps. In this algebra lesson, students idenitfy different maps and explore how they relate to the area keeping cllimate and topography in mind. They discuss maps used to navigate land. air and sea.

For this algebra worksheet, students describe the relationship between a line graph and its data. They define the reasons line graphs are used and discuss increasing and decreasing lines. There is one involved questions, requiring...

Students create bank reconciliation spreadsheet. For this algebra lesson, students discuss the basics about business, money and bank accounts. They use a bank reconciliation statement correctly.

Students perform operations and graph their data using charts and bar graphs. In this algebra lesson, students follow specific steps to make a bar graph. They create a survey about people favorite things and plot their data from the...

Student are able to devise and use problem solving strategies to explore problems systematically and mathematically. They also form and solve various types of equations. This lesson requires some prior knowledge of equations.

Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.

Students use candy bars, beef jerky, and brownies to represent different fractions. Students also use colored multi-link cubes or blocks to illustrate the same representations of fractions. Students work with a partner to create diagrams...

Explore the connection between operations with scientific notation and the laws of exponents. Scholars work on a set of word problems involving operations with scientific notation. Along the way, they consider how the laws of exponents...

Ninth graders are investigating slope of a line. The line is plotted using the slope and points on a line. They also write an equation given the right information. The use of a PowerPoint is part of the presentation.

There are many ways to work through a multiplication problem. Using an area model, kids complete several worksheets with different types of multiplication problems, including multiplying by ten, and explain how the new strategies differ...

Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.

How can you model exponential decay? Explore different situations involving exponential decay functions and decreasing linear functions by performing activities with MandM candy, popcorn kernels, and number cubes.

Demonstrate the meaning of an absolute inequality using three different methods. Here, scholars explore absolute value inequalities through graphing, number line distance, and compound inequalities. Pupils complete various activities to...

Word problems offer class members an opportunity to learn the concept of solving linear systems using graphs. Individuals choose a problem based upon preferences, break into groups to discuss solution methods and whether there...
