In this video segment from TV 411, two Atlanta Hawks players plan a driving route to reach the Basketball Hall of Fame. They use map scales to estimate their travel distances.
" Western philosophy and theoretical mathematics were born together, and the cross-fertilization of ideas in the two disciplines was continuously acknowledged throughout antiquity. In this course, we read works of ancient Greek philosophy and mathematics, and investigate the way in which ideas of definition, reason, argument and proof, rationality and irrationality, number, quality and quantity, truth, and even the idea of an idea were shaped by the interplay of philosophic and mathematical inquiry."
Bianca visits a bike shop and learns how bicycle gears work in this Cyberchase video segment.
In this Cyberchase video segment, the CyberSquad calculates the speed of each broom.
Students will work together in small groups of four to six students to solve the following word problems. Their solutions will require them to practice interview techniques and create a database and/or spreadsheet of their results. This information will be the basis of the answers to the following eight word problems. Skills such as area, cost, calorie count, ratio, percentage and scale, as well as persuasive writing will be applied.
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.
The CyberSquad tests which broom can travel the furthest in five seconds in this video from Cyberchase.
This lesson is part of an interdisciplinary integrated unit on DNA and genetics. The idea is for students to complete a week's worth of activities in science, math, and language arts. This lesson is Part B: Math. Students will complete a math survey interviewing people on whether they believe humans should or should not be cloned. They will take the data they gather and create computer generated spreadsheets, charts/graphs. Using the charts/graphs, students will answer mathematical percent and ratio questions and write a final journal entry on the information they collected and discovered.
This module discusses the different scales used in statistical analysis and what levels of measurement are used in psychological variables. The terms discussed are Nominal, Ordinal, Interval, and Ratio scales.
This module provides word problems which develop concepts related to direct variation.
This module provides sample problems which develop concepts related to extrapolating a function from a set of data points.
This module provides sample problems which develop concepts related to using linear regression on a calculator to find the variation of data.
This module provides practice problems related to direct and inverse variation.

For high school and above, a discussion of the relationship of musical intervals and frequency ratios, with examples and exercises.
An overview of some of the math concepts that are relevant to music. Includes suggestions for classroom activities for grades 3-7 that use music to illustrate a math concept, as well as reviews of the math necessary for older students to understand some music theory and acoustics.
From politics to cookery, ratios, proportions and percentages are part of everyday life. This unit is designed to help you become more familiar with how figures can be manipulated, then you can check whether that discount really is as big as they claim!
This learning object focuses on basic understanding of ratios and proportions and is part of the Kentucky Learning Depot, Kentucky’s P-20 repository for digital learning content. This math learning object replicates what might take place in a classroom, beginning with objectives, examples, and opportunities for users to practice and get feedback. This is appropriate for multiple grade levels throughout K-12 and some post-secondary, both “academic” and “technical” in application.
