Students examine folk’s tales for Cause and Effect. In this literature lesson, students read "The Origin of Fire" and "The Origin of Medicine” and look for cause and effect. They use a TI Navigator to write down their findings.

Pupils investigate the area and circumference of a circle. In this geometry lesson, students estimate and measure the radius, diameter and circumference of a circle. This assignment has an online part that is interactive.

Students compare and contrast exponential and power functions. In this precalculus lesson plan, students identify the value of x, using the graph as a visual. They compare functions with base of greater than one, to base of less than one.

Students explain the role of genes in heredity. In this biology lesson, students predict the offspring's genotypes and phenotypes using the Punnett Square. They compute the probability of genotypes and phenotypes.

Students calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.

In this variation activity, students interpret and organize data.  They find the distance between points.  Students use ratios to determine volume  This six-page activity contains approximately 20 problems.  Answers...

Students measure the relative heights of the mosaic giraffe and its trainer and compare their proportions to an actual giraffe and zoo trainer.

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Pupils create visuals of the effect of a spring scale. In this algebra lesson, students use the navigator to graph the effects created by a spring scale. They draw conclusion from the graph.

Students find and define the slope of a line. For this algebra lesson,students differentiate between positive and negative slopes. They define the properties and slopes of vertical and horizontal lines.

Young scholars explore the surface ratio of an object.  In this surface area to volume lesson students construct a data table, make calculations and create a graph. 

Young scholars explore the concept of probability. In this probability lesson plan, students use a applet that demonstrates chaos and probability of spread for a forest fire. Young scholars also play applets about the Game of Life and...

Students design a budget to plan for a class party. In this problem solving lesson, students devise a budget with a limit of fifty dollars for a class party. Students discuss and estimate the amount of money needed for food and decorations.

Students research chemical formulas and balance chemical equations.  In this chemical equations lesson plan students complete a class activity on chemical equations and answer questions.

Pupils explore percent increases and decreases. They calculate the percent increase and decrease. Students use math to solve problems and communicate. They apply the given formula for percent increase/decrease.

In this chemistry review worksheet, students solve a variety of problems including balancing equations, solving for unknowns using dimensional analysis, finding percent yields, limiting reactants and empirical formulas.

Eleventh graders investigate infinite geometric series.  In this Algebra II lesson, 11th graders explore partial sums of geometric series, converging and diverging series, and sums of infinite geometric series.   The...

High schoolers pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Eighth graders extend skills for representing and solving linear equations to linear inequalities. Lesson activities build understanding and skill by plotting ordered pairs of numbers that either satisfy or do not satisfy a given...

Students derive the six trigonometric identities. In this trigonometry lesson, students review the parts of a right triangle and use the Pythagorean theorem as a guide to find the trig identities. They find sine, cosine and tangent ratios.

Learners apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. Learners define the use...

Learners explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Learners use the Perimeter Explorer applet to find the perimeter of various shapes.

Young scholars solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.
