Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

Learners explore scatter plots in this algebra instructional activity. They create a scatter plot from their guesses regarding a famous person’s birth date and the actual birth date then they examine and interpret the results of their...

Learners explore the concept of distance v. time. They use a CBR to collect data on their distance over time, then plot their data using a scatter plot and find an equation to model their data. Pupils discuss what if scenarios which...

High schoolers investigate perimeter patterns formed by a hexagon and a triangle. They will identify the dependent and independent variable and write a function for the relationship.

Ninth graders assess the accuracy and reliability of current survey data and how it is represented. They design a survey, collect data, and use technology to analyze the data and present the results. Students examine scatter plots and...

Practice using linear models to answer a question of interest. The 12th installment of a 16-part module combines many of the skills from previous lessons. It has scholars draw scatter plots and trend lines, develop linear models, and...

Adjust this lesson to fit either beginning or more advanced learners. Build a scatter plot, determine appropriate model (linear, quadratic, exponential), and then extend to evaluate the model with residuals. This problem uses real-world...

Learners investigate relations in this algebra lesson. They graph the set of ordered pairs that determine a relation. Using a TI-83 Plus, your learners will enter the coordinates in a list, create a scatter plot, and manipulate the...

Learners explore reflections on a coordinate plane in this instructional activity. They trace their hand on a grid, determine the coordinates of each point, and create a scatter plot of their points. Pupils use this information to...

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.

Pupils explore the law of reflection. Through experimentation and problem solving, they collect and analyze data pertaining to reflection. The data is plotted on a graph and formulas for calculating the x and y values are evaluated.

Through learning how to examine linear, quadratic, and exponential functions, students explore the effects of changes in parameters on the graphs of linear, quadratic, and exponential functions.  The lesson is designed to be a...

Investigate differential equations with your class. They use the TI-89 to explore differential equations analytically, graphically, and numerically as the examine the relationships between each of the three approaches.

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.

Pupils play a game and collect data for their graph. In this algebra lesson, students solve quadratic equations and identify properties of their graph. They describe the pattern created by the graph and the game.

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

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