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.

Fourth graders study how atmospheric conditions change while naming the things that make the weather change. They investigate the affects of air masses, weather fronts and high/low pressure by looking at weather maps from newspapers.

Students research types of chromatography and complete chromatography experiments.

First graders complete center activities as they practice their addition and subtraction skills. They listen to Rick Walton's, "How Many, How Many, How Many" before playing games, and completing addition and subtraction worksheets at...

In this letter symbols worksheet, students solve and complete 4 different types of problems. First, they circle the expressions that are the same as the one shown. Then, students find the value of each symbol. In addition, they simplify...

In this introduction to approximation theory, students compute the slope and intercept of a line. They describe nonlinear relationships. This four page worksheet contains approximately five problems.

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

In this thermodynamics instructional activity, 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...

Fifth graders explore the math concept of graphing integers. In this graphing integers instructional activity, 5th graders examine visual examples. Students also practice solving problems that their instructors model.

Eleventh graders define various types of linear systems and three types of solutions. In this linear system and echelon forms lesson, 11th graders solve a linear system using elementary row operations. Students also describe the set of...

Students explore Cuisenaire Rods.  In this pre-algebra lesson, students work with a partner to generate addition problems with the sum of ten using Cuisenaire Rods. Students construct examples of the Commutative Property using...

Students solve linear equations. For this algebra lesson, students solve equations using addition, subtraction, division and multiplication. They evaluate and simplify functions.

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

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.

student make predictions or draw conclusions based on physical and visual representations of profit and sales. They model problems with physical materials and visual representations, and use models, graphs and tables to draw conclusions...

Students discover patterns in linear equations by playing a dice game to collect data. They graph the data and analyze the patterns of the lines created by the data. The class then compares the individual graphs to evaluate the position...

Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

Students view examples of Robert Harris' artwork to identify and describe the ecosystems in them. In groups, they work together to discuss how ecosystems breakdown and create solutions to keep this from happening. To end the lesson,...

Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

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

[Free Registration/Login may be required to access all resource tools.] Practice forming the largest and smallest numbers given a set of 3 digits, two of which are unknown variables, in this learning module. Includes video demonstration...

Examples and video tutorials that teach how to solve equations that contain unknown variables.

Students will learn and reinforce skills for solving for unknowns, manipulating equations while keeping them in balance, using formulas to solve real-world challenges, and working with proportions, radicals and exponents.

Solve a linear equation for a variable where the coefficients are represented by letters. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.
