In this phase diagram worksheet, students use a phase diagram to determine the critical point, phase boundaries, and phase transitions. This worksheet has 20 problems to solve.

Students solve systems of 2-by-2 linear equations using tables, graphs and substitution. In small groups, classmates work together to discover strategies for solving equations. They use a calculator to graphically represent their answers.

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 explore the concept of logarithms.  In this logarithms lesson, students graph logarithms on their Ti-Nspire calculator.  Students describe the shapes of their graphs by identifying slope, y-intercepts, and roots. ...

Students engage in a lesson that is concerned with the rules of exponents. They practice solving problems that use exponents in a variety of contexts. Students are shown how to use the rules in numerical sequences and after translation...

Students explore perimeter and area of rectangles. In this rectangular lesson, students use tiles to discover the formulas for perimeter and area. Students solve for area.

Young scholars analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life...

Students practice different skills of mathematics used when working with exponents. The lesson has examples that can be used during direct instruction. They complete an exercise on a worksheet before advancing to a new standard.

Students examine how driving a hybrid car can save money and cut down on pollution.  In this hybrid vehicles instructional activity students complete an exercise that shows them how to work with proportions, percents, dimensional...

Fifth graders discuss the relationship between equivalent fractions, ratios, and proportions. In this fraction lesson plan, 5th graders answer questions about a punch mixture in order to find the ratio of ingredients.

In this solving linear systems worksheet, students solve twenty-four systems using the substitution and elimination methods.  Definitions and examples are provided.

Students examine and discuss typical linear equations, and the difference between a linear and nonlinear equation. They observe examples of linear equations and complete a worksheet.

For this population worksheet, students read word problems relating to population growth. They write the problem as a differential equation, create models and graphs of the solution. This three-page worksheet contains 10 multi-step...

Students investigate growing patterns. In this additive patterns instructional activity, students analyze the core of growing patterns. Students extend additive patterns based on the core.

Sixth graders solve two-step equations.

Seventh graders discover that there are multiple strategies to be used in problem solving. They explain a problem solving situation in their own words and determine a possible strategy for solving the problem.

Eighth graders evaluate statistical equations. They examine data from archaeologists at Jamestown, complete statistical equations using the sets of data, and graph the results.

Students research propulsion, graph data, and interpret the results.

Second graders use a number line to practice subtraction.  In this subtraction lesson, 2nd graders use a number line to count backwards.  Students participate in mad math activities and solve problems.

High schoolers, after reading an explanation from a NASA Web site, demonstrate an understanding of the text by applying it to questions involving Maximum Flight Time and Range under varying conditions.

Fourth graders listen to the problem to the class and think about how they solve the problem and to discuss it with their friends using number sentences in their written record of the solution.

Students, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity to graph and interpret the lift equation.

Young scholars complete a variety of bear-related activities. They sort and graph teddy bears, distinguish between real and non-real bears and research bear life cycles and habitats.
