High schoolers graph linear and quadratic functions. In this algebra lesson, students create graph with specific coordinate points. They use the Ti to visualise and differentiate between the two functions.

Students test the hypotheses using p values. In this statistics lesson, students define and examine conditional probability. They test each statement for a true statement or a false statement, based on the sample size.

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..

Students conduct and analyze a survey about snacks. In this graphing instructional activity, students ascertain which snacks would be the best choice for the community. Students hold a sale and decide how the money could best be spent...

Students learn the meaning of LD50 through lecture and discussion. Through experiment, students graph and calculate the LD50 of salt on fresh water amphipods. Students compare results of the experiment with pesticides and pollutants.

Using their Ti-Nspire to determine the solutions of parabolas, learners explore the concept of complex roots.  Students determine if parabolas have real or complex roots.  Learners determine the the axis of symmetry and the...

Learn how to evaluate the derivatives of polynomials.  Mathematicians find the derivative of a quadratic function and determine the value at a given value.  Students compare the slope of the secant line through two points with...

Learners calculate percent change and create lists of data. They enter the corresponding bushels of corn measured in billions to their list and display, then convert the acres into scientific notation and use the value on the home screen...

Third graders work in groups to create an edible resource map showing locations of at least five resources in the United States. Students research on the internet different regions and the resources that are found in those areas. They...

Students investigate chords and make predictions. For this geometry lesson, students graph circles and calculate the measurement of each chord. They perform the calculations and make conjectures.

Learners develop a cultural understanding of "Grab Day." Using magazines, they clip out pictures to make collages of items thrown down to people on this day. Students label the items in their collages.

Calculus students find the limit of piecewise functions at a value. They find the limit of piecewise functions as x approaches a given value. They find the limit of linear, quadratic, exponential, and trigonometric piecewise functions.

Mathematicians explore cubic functions by learning how to investigate the relationship between the x-coordinates of the three zeros of a cubic function.  The lesson also contains an application of differentiation. 

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

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 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.

Students examine complex numbers. In this Algebra II lesson, students investigate two programs that involve complex numbers: the MANDELER Program and SYNDIV program.

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 sit in a circle with their bears from home, each child introduces their bear, then students examine all the bears and think of one way that they can be sorted.

Students research and plan a Mississippian garden.  In this Native American history instructional activity, students work in groups to research crops used by Native Americans in the Mississippian Period and use the information to...

Students dilate functions using transformation. For this algebra lesson, students complete vertical dilation, stretch and shrink. They perform reflection across the x and y axis.

Young scholars solve problems dealing with ratios and proportions. For this algebra lesson, students rewrite word problems using equations and symbols. They correctly convert between percents and decimals.

Students apply the Fundamental Theorem of Calculus. In this calculus lesson, students identify the graphical connections between functions and accumulation functions. They use a TI to represent the functions.

Students solve the area of a cross section. In this calculus lesson, students solve areas rotated and bounded by two functions. They solve using the washer method.
