Twelfth graders problem solve limit/function value situations. They solve the problems using a graphing calculator, which allows them to see the function's graph, and infer the function value and limit from the graph.

Students identify the quadrants and axis of a coordinate plane. For this algebra lesson, students discover the ocrrect way to graph using the coordinate plane. They discuss the relationship between x and y values, domain and range and...

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Students work in pairs to measure their arm span and height and record them on a class chart. The class works together to create a scattergram to display the data. Class discussion focuses on interpreting the scattergram.

Students graph coordinate points to create a picture of Snoopy. In this coordinate point lesson, students read a book and learn about Rene Descartes' invention, the coordinate grid.  Students graph a surprise picture on...

Students explore basic connections between graphs, tables, and symbolic representations for lines, parabolas, inverse models, and exponential models. One of the primary goals of this lesson is to help students begin to recognize patterns...

Students use calculator and non-calculator methods for analyzing data. They apply data collection and analysis in a study of mass and weight. Students enhance and apply the concept of line of best fit. They master graphing in a plane,...

Tenth graders study graphing exponential functions. In this transformations instructional activity, 10th graders apply inquiry to determine how changes to a parent function affect its graph. Students analyze transformed graphs and...

Students use the calculator to represent a situation as a table, graph, and equation. They write systems of equations and find solutions to systems of equations. In addition, they explain and justify how they determined their solutions...

Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.

Middle schoolers differentiate between biotic and abiotic factors in this science lesson. Learners collect data for the experiment and analyze the data after graphing it using the CBL 2. This experiment is split into two different...

Learners calculate the sides of right triangles in this trigonometric ratios lesson. They use Cabri Jr. software and TI-83 or TI-84 calculators to find the side lengths and their ratios to each other for various triangles. The provided...

Students write systems of equations and find solutions to systems of equations. They explain how they determined their solutions to a system of equations and justify their solutions. In addition, they write equations in standard form and...

Students study the work and accomplishment of Galileo. In this physics lesson plan, students calculate the period of a pendulum's using a mathematical equation. They explain the different factors affecting its period.

Students study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Students also graph the data they collect and...

Students investigate the necessity of water for the survival of plants, animals, and people. They explore the affect that water has on human and natural environments through literature, field trips, and discussions.

Eighth graders calculate a system of equations to find the best ticket price for a ticket at a water park. They explain how the equations helped them make their decision on the best price.

Learners explore an exponential relationship and how it relates to human population growth and the current global population crisis.

Fifth graders find the area of rice farms. In this area instructional activity, 5th graders draw shapes and grid them to find the area. They compare different rice fields to see which one takes up more space and has the larger area. 

Fourth graders represent a new predator on a population of colored worms. They mathematically determine the effect of the new predator on the survival and reproductive rates of the worms, simulating natural selection at work.

Predict the future of education through a mathematical analysis. Using a project-based learning strategy, classes examine the pattern of student-to-teacher ratios over a period of years. Provided with the relevant data, learners create a...
