Using Kleiber's rule- which linked an animals metabolic rate to its mass- to motivate working with rational exponents, this lesson begins by linking work with $$n$$th roots from the last le

The four arithmetic operations on fractions are given here, but in each case examples of using the operation on ordinary fractions is first reviewed, helping to ground the new material in the unde
The lesson begins with a definition of a "complex" fraction and then presents a procedure for simplifying them (multiplying the numerator and the denominator by the lcd of all fractions contained
Students will make the necessary conversions using basic equivalency tables for standard measurements used in cooking.
This activity, created by Arthur N. DiVito, Ph.D, simulates mixture problems by using red and white colored beads. Mixture A is 70% red, and mixture B is 40% red (as determined by weight).
Students will be presented with two different gas stations, and will have to come up with equations to determine the price of gas at each.
Students will calculate relationships in the solar system using scientific notation. This requires that students understand how to multiply and divide exponential expressions.
Using systems of equations, students will determine the missing components in the ratios used to determine batting average.
he main purpose of this lab is to explore the proportionality of forearm length and height. The students will record their heights and forearm lengths, first plotting on a table.
In this activity students will explore levels of Carbon Dioxide (CO2) in the atmosphere over time.
