Fifth graders utilize input/output tables to help them solve algebraic equations. They incorporate patterns, number sequences and relations to represent and analyze mathematical problems and number relationships using algebraic symbols.

Ninth graders translate sentences into equations. They translate equations into sentences. They solve real life problems using verbal models to write equations. They create a problem solution graphic organizer in their journals.

Students use input / output tables to help them solve algebraic equations. They use patterns and relations to represent and analyze mathematical situations using algebraic symbols.

Students solve equations of the form ax+b=cx+d and visualize the concept of "balancing" an equation.

Young scholars participate in numerous activities and games. In pairs, they play card games to find relationships between a random set of playing cards. After writing samples of Dear Abby letters concerning math problems, students...

In this gases worksheet, students review the kinetic molecular theory and use the ideal gas law to solve 20 problems.

In this thermodynamics worksheet, students define and give examples of state functions. Students review the laws of thermodynamics. Student determine the standard formation reactions for given chemical species. This worksheet has 10...

In this physics worksheet, students solve 6 problems where they calculate average speeds of moving objects, distance objects travel and time it takes for objects to get to their destination.

In this simple equations worksheet, students examine diagrams and write equations to support the information in the diagram. This one-page worksheet contains 10 problems. This worksheet may be completed on-line or produced in printed...

Learners explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...

Students are given three unknown samples and must perform two chemical tests in order to determine if the samples contains protein and/or starch. Students work with corrosive or toxic reagents.

Students gain knowledge by measuring time and distance for solving unknowns in an equation. They also will design an airplane and chance to communicate mathematically by writing essays.

Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental lesson plan, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of unknown pH....

Students investigate the currency exchange rate.  In this middle school mathematics lesson, student use proportions to exchange between the U.S. dollar and the euro.  Students come up with a product they would like to buy and...

In this Algebra II worksheet, 11th graders investigate matrix multiplication. The two page worksheet includes instructions and examples and two problems. Solutions are included.   

Fourth graders study about sound waves and how they behave in various media. They create a soundproofed container. They explain that velocity describes a change in distance over time.

Students 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 situations.

Students compete in playground games in order to review velocity and wave behavior in real life situations. They demonstrate understanding by calculating velocity in their "Playground Games" packet.

In this discrete least squares worksheet, students use a linear algebra approach to discrete last squares approximation. This two-page worksheet contains approximately 10 problems.

Young scholars investigate growing patterns. In this additive patterns lesson, students analyze the core of growing patterns. Young scholars extend additive patterns based on the core.

Children will learn the term variable and then work to "attack" a problem using what they know about the relationship between multiplication and division to solve for an unknown.

Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the...

In this task, two brothers track how many games they have each won. Students are asked to make calculations based on the percentage of games won. They set up a rational equation (and a rational inequality) in one variable, and then solve...

The lesson plan provided here gives a step-by-step set of instructions for balancing an equation in order to find the value of the unknown variable. After two examples are worked through, 10 practice problems are given, as well as their...
