This tutorial shows you how to enter a set of data and find the line of best fit.

Students examine the USA TODAY Snapshot "More of U.S.", construct a graph from the data, produce a mathematical model (linear) for the data, determine the rate of change for the data, and make predictions about future population levels.

In this activity, students will find and compare function rules for a given pattern. They also evaluate variable expressions.

This activity will use the capabilities of their graphing calculator to illustrate the symbolic derivative product rule.

Students study quadratic relationships and explore the process of graphing quadratic inequalities and systems of quadratic inequalities. They will solve these inequalities algebraically and graph them on a coordinate plane.

The following LearningCheck file was created for educators in Texas to have supplemental assessments in preparation for the 9th grade TAKS exam. The assessment involves topics covered in Objectives 1-4 in the 9th grade objectives.

Solve equations and find zeroes of functions using the TI-83 in this lesson. Keystroke instructions and calculator screenprints are included to help students with the activity.

Students will examine the current and predicted population data from the countries included in the USA TODAY Snapshot "Growing bigger by the decade".

In this activity, students will perform a series of experiments with inclined planes. They will learn that as the angle of inclination of the inclined plane approaches 90 degrees, the value of the acceleration of the cart traveling down...

The student is given actual data and asked to find a line of best fit and to give "real world" interpretations of the slope and y-intercept. A great introduction to the 83/84 and its features.

In this activity, Students can use colorimetry to determine the concentration of a colored species in a solution and use a linear relationship to model Beer's law. They use Beer's law to determine the concentration of...

This activity center is used to illustrate the difference between the slant height and the actual perpendicular height (of the given square pyramid) by the use of the distance formula.

This is a set of problems involving the concepts of integrals in context. The problems are similar to those encountered during the fourth quarter of a typical calculus course.

This activity is set up as a game in which paired young scholars each pick a function and predict the area between the two curves without knowing the other person's function. The students then find the area between the functions and...

The students will determine the correct number of significant figures and apply rules for significant figures in calculations.

Based off of the hit television show NUMB3RS, this lesson introduces students to the set of Fibonacci numbers and shows how this set is present in many aspects of nature. Through the lesson, students explore the first 13 elements in the...

This activity will define procedures for computing instantaneous rates of change exactly and, when exact is impossible or impractical, approximately. (Continued. See "before the activity.")

Students explore curve fitting and translations of the parabola.

In this activity, students will measure round objects to determine the circumference and diameter, and use the data to explore geometric concepts of the circle with statistics.

In this activity, students' will use a pH sensor to check and compare the pH values of various water samples. They will understand the meaning and effect of pH and factors that affect pH.

In this activity, students' will use a motion detector to record distance and velocity versus time information for a walker. They find the area under the velocity versus time graph and compare it to the actual distance traveled by the...

Students can use this LearningCheck item bank to prepare for the CRT exam.

This StudyCard stack teaches and tests on the linear function. Shows connection between the function parameters and the resulting geometric behaviors of the linear function. Use with Foundations for College Mathematics, ch. 2.3, 4.1.

Students can use this LearningCheck item bank to prepare for the Nevada CRT math exams.
