Wolfram Math World: Pie Chart

Movie preferences will get your classes talking! Individuals read a pie graph and construct a bar graph using the same information. They then answer questions specific to the data and sample size.

Representing data is as easy as pie. Class members construct pie charts given a frequency table. Individuals then determine the size of the angles needed for each sector and interpret the size of sectors within the context of frequency....

Using the interactive, pupils create a pie chart that represents the percentage of sodas bought for a party. Individuals need to determine the percentage and number for the final variety of drinks. The learners determine how the...

Easy as pie ... with a little work anyway! A complete lesson provides video instruction on creating a pie chart from a set of data. The practice that follows helps learners draw their own pie charts while practicing skills from the...

Not pi, but pie! A video instructor explains how to read and interpret a pie chart. The lesson shows the best way to identify the part of the population in each section of the pie using fractions and/or percents.

Given populations of the five Northwestern states, learners create a circle graph. Using the data and the pie chart, they make comparisons between the populations of the states. Finally, the pupils determine how the chart will change...

MathWorld provides a huge mathematics encyclopedia detailing the concepts of geometry, algebra, calculus, discrete math, number theory, and other math topics--complete with formulas, diagrams, examples, and references for thorough...

This webpage thoroughly discusses the math of spheres. Includes the equation for a sphere in Cartesian and spherical coordinates as well as parametrically. Surface Area, volume, and curvature are addressed at this extensive site.

Forget hours, divide the day into radians instead. Class members convert the angles in a pie chart of daily activities into radian measures. They add angle measures for multiple activities then determine a relationship between the radian...

This math site gives the formula for taking the dot product of two vectors, gives properties of dot products, (commutative, associative, and distributive), how to find the derivative of a dot product. This site has links to several other...
