This online manipulative features a virtual balance scale. It offers students an experimental way to learn about solving linear equations involving negative or positive numbers. The applet presents an equation for the student to illustrate by balancing the scale using blue blocks for positive units and variables and red balloons for negative units and variables. The student then works with the arithmetic operations to solve the equation. A record of the steps taken by the student is shown on the screen and on the scale. The applet reinforces the idea that what is done to one side of an equation must be done to the other side to maintain balance. Instructions for using the applet, background information about solving equations, and teaching suggestions are included.

This interactive applet allows students to explore cut-outs of polyhedra, including a tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The applet begins with each shape "unfolded" to its two-dimensional form. The slider bar allows students to fold the shape into its three-dimensional form. Students can experiment by folding the sides independently and rotating the shape. This applet can help students understand concepts of surface area and decomposing 3D shapes into 2D elements.

This site gives a description of how to divide fractions and gives a sample problem in which the denominator fraction is inverted, the numerators and denominators are multiplied, and the resulting fraction is simplified. It also includes the same problem solved by 'canceling' the fractions to simplify, and completing the process. There is also a game for students to practice their new skill of dividing and simplifying fractions.

This applied mathematics lesson features hands-on activities supporting the NCTM Measurement Standard, and can be used to introduce middle school students to a bit of real-world measurement, trigonometry, and geometry through mechanical drafting. All that is needed are measurement tools ŰÓ carpenterŰŞs square, a piece of string, and a protractor. In it, students read an introduction about the importance and various uses of applied trigonometry and practice by examining the classroom and identifying which objects would have been designed by a mechanical drafter. They then discuss which aspects of the object would need to be measured and how those measurements would influence the design. Students practice by placing a string across the carpenter's square and use the Pythagorean Theorem to perform calculations on the right triangles produced. There are a series of extra activities in which students measure classroom objects to solve practical problems.

This game presents students with a number and asks them to find all the factors (divisors) of it between 1-10. There are two modes: the first uses numbers 1-100 and the second uses 101-999. Students then select which numbers are factors and try to open the safe. If they are correct, the safe will open. If they are incorrect, the simulation gives a hint as to how many they have correct and two more tries. There is a calculator built in to the site for students to use to help solve each problem.

This lesson introduces students to linear equations in one variable; shows how to solve them using addition, subtraction, multiplication, and division properties of equalities; and allows them to determine if a value is a solution, if there are infinitely many solutions, or no solution at all. The site contains an explanation of equations and linear equations, how to solve equations in general, and a strategy for solving linear equations. The lesson also explains contradiction (an equation with no solution) and identity (an equation with infinite solutions). There are five practice problems at the end for students to test their knowledge with links to answers and explanations of how those answers were found.
