Pupils investigate linear, quadratic, and exponential regressions. They plot sets of data points, determine the regression equation that best fits the data and lastly investigate the coefficient of determination.

Students investigate quadratic functions using geometric toothpick designs. They review transformations of quadratic functions-vertical and horizontal shifts, and stretches and shrinks. Students match the symbolic form of the function to...

Learners investigate the differences between linear and exponential models.  In this linear and exponential models lesson, students make a table of given data.  Learners determine if the data is linear or exponential by...

Students convert degrees between two different units. In this algebra lesson, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.

Students read about the changes in the "new money" and then create a graph to represent various combinations of currency produced.

High schoolers analyze data and identify the mean. In this probability lesson, students log data in the TI and construct scatter plots from the data. They identify properties of a scatterplot.

Learners identify the line of best fit. In this statistics lesson, students analyze graphs and plots to identify positive, negative or no correlation. They find the line of best fit for different scatter plots.

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

How well does your garden grow? Model the growth of dahlias with nonlinear functions. In the lesson, scholars build on their understanding of mathematical models with nonlinear models. They look at dahlias growing in compost and...

Tune in for savings! Scholars investigate pricing schemes for two different online music download sites. After comparing the two, they determine the numbers of songs for which each site would be cheaper.

How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...

Learners collect data and create a graph. In this algebra instructional activity, students describe functions graphically, algebraically and verbally. They identify functions as being independent and dependent using variables.

Learners survey the class and graph the results. In this graphing and data collection lesson, students conduct a survey to see where their shirts were produced. Individuals use software to graph the results and create a written...

Students solve systems of equations with radical expressions. After reading real life situation, they translate the problem into algebraic expressions. As a class, students solve quadratic equations and inequalities by graphing and...

Students collect data on population growth. In this statistics lesson, students graph their data and make predictions. They find the linear regression and the best fit line.

Students analyze data representing real life scenarios.In this algebra instructional activity, students collect, plot and analyze data using a graph. They use different methods to represent and present their data.

Eighth graders extend their learning of graphing linear equations and are introduced to connecting patterns in tables and graphs to represent algebraic representations. They then determine patterns and extrapolate information from these...

Students solve word problems using the correct math symbols. In this algebra lesson, students use the TI calculator to graph their equation and analyze it. They find the line of regression and use to draw conclusion.

Students make "pets" of isopods (potato bugs) to determine their preferred environment and food sources. They record their results on a bar graph and in a scientific report.

Students model data using quadratic equations. In this algebra instructional activity, students simplify and factor quadratic equations. They graph the function using collected data and analyze the parabola.

Young scholars develop a formula that describes the functional relationship of the circumference of a circle to its diameter. Working with a partner, they measure the diameter and circumference of circular objects in order to discover...

Students observe a pendulum and graph their observation. In this algebra lesson, students use the TI calcualtor to graph the motion the pendulum makes. They analyze the graph and make predictions.

Students create graphic, algebraic and verbal ideas of functions. In this algebra lesson plan, students graph functions and identify the zeros of the functions. They find the domain and range and classify functions as relation or not.

Young scholars factor and solve quadratic equations. In this algebra instructional activity, students play a game as the collect and graph data. they identify properties of their parabola and make predictions.
