High Schoolers engage in a study of circles and graphs that are related with the focus upon finding the center and radius. The lesson includes the suggestion of giving homework using circle problems before this one to create background...

Learners practice finding the areas and patterns within a square and explore the concept of quadratic functions. They observe and record the area values in a table, plot a graph of Area versus Distance and complete a variety of student...

Mathematicians measure intersecting lines-and circles, and create chords. In this geometry lesson, students explore interrior and exterior chords created by tangent and secant lines. These segments can be inside the circleor outside the...

High schoolers explore the proportional relationships involved in multiple parallel lines being cut by a transverse line. They complete a sail design problem, that involves finding the lengths of pieces of fabric along the edge of a sail...

The investigation of exponential equation in the context of increasing college tuition costs is explored through this lessib.  Learners write exponential equations based on the percent of change of college tuition and use their...

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.

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.

Middle schoolers differentiate between biotic and abiotic factors in this science lesson. Learners collect data for the experiment and analyze the data after graphing it using the CBL 2. This experiment is split into two different...

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

Students explore slope.  In this middle school mathematics lesson, students analyze and interpret graphs as they investigate slope as a rate of change.  Students use a motion detector to collect data as they walk at different...

Learners find the length of diagonals.  In this Pythagorean theorem lesson, students use the Pythagorean theorem to determine the length of diagonals. 

Students explore the concept of exponential growth.  In this exponential growth lesson, students manipulate power models with base 2.  Students discuss what would happen if you doubled a penny over the course of 20 days. ...

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...

Eleventh graders investigate arithmetic sequences.  In this Algebra II lesson, 11th graders create an arithmetic sequence and explore the effect of each variable in the formula of the nth term of an arithmetic sequence. ...

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students explore proportional reasoning.  In this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.

Teach how to explore exponential equations.  In this Algebra II lesson, students investigate the graph that occurs as a hot liquid cools.  Students model the data algebraically.

Students linearize data to determine if an exponential model is suitable. In this linearizing data to determine if an exponential model is suitable lesson, students graph the residuals of sets of data that appear to have an exponential...

Ninth graders investigate divisibility rules.  In this middle school mathematics/Algebra I lesson, 9th graders explore the divisibility rules of 7, 11, and 13.  Students examine certain six-digit numbers that are divisible by...

Students investigate the growth rate of a man named Bob Wadlow.  In this growth rate of a man lesson, students determine if the growth rate of this particular man was normal or abnormal.  Students bring in data of their height...

Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile.  Students launch baseballs on a football field and video tape the path of the ball.

Pupils explore the relationship between area and perimeter of polygons.They measure the area and perimeter of regular polygons inscribed in a circle. Learners then discuss how as the number of sides of a regular polygon increase, the...

Students investigate the skin surface to body area ratios for different animals.  In this seventh/eighth grade mathematics/science lesson, students explore heat transfer between an animal’s body and the environment.  Using...

Students investigate data collection and analysis.  In this Algebra I instructional activity, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.
