In this learning activity you'll calculate percentages using a grid to solve problems.

In this learning activity you'll practice using the keys on the Casio fx-260 Solar Calculator.

Learners examine how metal detectors function. This object includes animation and sound.

Users study a chart containing numbers 1 to 99 and look for trivial palindromes as well as double and triple iteration palindromes. The reverse and add technique is demonstrated.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?

In this learning activity you'll read and listen to English words from the French language.

Learners will identify the number of significant digits in practice problems.

Learners examine the use of the reciprocal key on the TI-83 Plus calculator to determine parallel resistance.

In this animated and interactive object, learners use an algebraic formula to solve a problem involving distance, rate, and time.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

In this animated and interactive object, learners view two examples of how to subtract fractions with unlike denominators and then work five similar problems.

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

In this learning activity you'll identify points on a coordinate system.

In this activity you'll calculate equations using the order of operations. You'll be introduced to what it is and how it works.
