Students calculate the slope of a line. In this slope instructional activity, students use a graph, an equation or two points to help them calculate the slope of a line. They differentiate between a slope of zero and an undefined slope.

Students observe and calculate slopes. In this algebra lesson, students graph equations and determine the pace at which the slope is changing. They use the navigator to see the change as they graph the lines around.

Students explore the significance of a resting and an active heart rate. In this heart lesson plan students chart data on their pulse and draw a diagram of the heart.

Young scholars analyze patterns of exponential models by collecting data in paper folding and M&M investigations. They use graphing calculators to create scatter plots that lead to equations for the exponential models. They then...

High schoolers explore the concept of Pi.  In this Pi lesson, students measure the circumference and diameter of a circle.  High schoolers record the diameter and circumference measurements from their classmates.  Students...

Students explore maximum and minimum points, slopes and tangents. In this Pre-Calculus lesson, students solve optimization problems and find rates of change.

Learners identify the different angles and sides of a triangle. In this geometry lesson, students identify the six trigonometric ratios. They graph the graph of each trig function and analyze it.

Learners collect and analyze voltage data. Then, they investigate exponential functions using the TI and a Voltage Probe and graph their data and analyze it using a table.

High Schoolers use the TI-83 calculator to produce a sequence, explore patterns and find a linear or quadratic equation for a given pattern. They use inductive reasoning to make conjectures about patterns. They find the Y-value of a...

High schoolers explore an application of definite integrals. They graph three functions that go through the same three points. Learners use the symbolic capacity of their calculators to find the shortest path through the three points and...

Learners explore the concept of quadratic equations.  In this quadratic equations lesson, students find the roots or zeros of quadratic equations using the quadratic formula.  Learners give examples of functions with 2 real,...

Pupils explore the concept of distance and time as they use a CBR to mimic distance v. time graphs. Learners walk towards and away from the monitor to create various distance v. time graphs, then discuss what motion creates certain graphs.

Pupils explore the concept of derivatives. They use implicit differentiation to determine points on a graph where a tangent line is horizontal, vertical, or oblique. Finally, learners find the derivative of a polynomial by...

In order to investigate local linearity, students graph the function on the TI-calculator and zoom to observe the change in slope on the line. They incorporate technology to visualize these problems.

Learners identify the critical points to a function. In this calculus lesson, students perform optimization of functions. They use the TI to create a visual of the graph.

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

High schoolers fill out an anonymous questionaire to explore whether they might have asthma. They then set up a spreadsheet to enter the data, decide on a definition of asthma, and figure out the prevalence of asthma. Pupils simulate...

Young learners explore motion graphs in this instructional activity. They investigate distance-time plots as they move in a specific way in front of the CBR in an attempt to make a motion plot that matches a given plot. Pupils explore...

Students explore the effects of population growth in Arizona.  In this history lesson plan, students work in small groups to create a "perfect" city. Activities include examining the Arizona census results then discussing the...
