Students learn the combined gas law, undersand how it incorporates all of the different relationships that they have already learned, and manipulate it to solve numberical problems.

Learners practice graphing relationships between variables by studying topics such as exponential growth and decay. They conduct a series of numerical experiments using a computer model and a variety of physical experiments using mold,...

Fourth graders control variables to determine the effect on plant growth. They collect information by observing and measuring and construct simple graphs, tables, maps and charts to organize, examine and evaluate information.

In this secondary mathematics instructional activity, students create a crossword review of algebra vocabulary.  The students must determine the correct answer to each clue and then determine the correct placement for the term in...

Learners explore the Method of Solution. They identify the components of the Method of Solution. Students develop the method of solution for a project that includes how the computer will be used, the mathematical equations needed to...

Second graders solve number sentences and examine how to apply basic operations of mathematics to those problems. They also use symbols to represent unknown numbers and how they are used in equations.

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 discuss Newton's 2nd and 3rd laws using the example of a football linebacker and a small child pushing against each other on an ice rink. Students are able to visualize the results of the push and link it to the laws. Discussion...

Students use the instructional activity, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by...

In this substitution and elimination worksheet, students complete short answer problems for substitution and elimination and read notes about them as well. Students complete 13 problems.

Use a worksheet to go over the basic concepts of relations and functions. Included are clear definitions and examples of relations, domain and range, and functions and the vertical line test.  However, the problems are pretty...

Seventh graders investigate the concept of functions and how they are used in the context of the real world while identifying the dependent and independent variables. They graph relations and functions and find the zeros of functions....

Students identify and test variables that may affect the accuracy of a rain gauge.

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 explore the concept of adding and subtracting using positive and negative numbers. In this addition and subtraction of signed numbers lesson, students use pennies to represent positive and negative numbers. Students deposit and...

Students germinate seeds in unflavored gelatin to which liquid house plant food has been added. Students observe and record plant growth in this medium with a variety of variables in a number of experiments.

Students practice solving very basic number sentences and recording their answers on a worksheet. Individually, they use different manipulatives to represent the sentence they solved. They also explain what steps were taken to solve...

Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...

Students compare transformations of a quadratic function on a graph and determine equations of a quadratic functions based on a reflection. They graph a transformation of a function based on reflections. They etermine if a function is...

It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

Apply systems of inequalities to a real-world problem. Here, scholars learn to graph solutions to systems of linear inequalities. To finish the lesson, they solve a problem involving burgers and cheeseburgers using a system of inequalities.

Sixth graders interpret linear and nonlinear graphs. They create graphs based on a problem set. Next, they represent quantitive relationships on a graph and write a story related to graphing.

Learners identify function using tables of data. In this algebra lesson, students create a tale of point and plot on a coordinate plane. They analyze the graph as being a function or not.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
