In this learning activity you'll identify and calculate the multiplication of monomials.

In this learning activity you'll examine how a sine bar is used to measure angles.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

The learner reads directions for finding the slope, intercept, and correlation coefficient for a group of ordered pairs using one of eight different scientific calculators.

In this learning activity you'll explore a graphical depiction of a radian for angular measurement.

In this interactive object, learners examine the properties of equality and use those properties to solve simple equations.

In this learning activity you'll use the Empirical Rule to calculate the percentages of data between two data points.

Learners review the basic math operations involving zero, emphasizing that division by zero is undefined. Examples are given.

In this learning activity you'll identify the sides of a right triangle with respect to the angles.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

Learners read how to convert complex numbers to their polar equivalent in Excel.

In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

In this learning activity you'll factor an algebraic expression of the form AX(Squared) + BX + C using the FOIL technique.

The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.
