Students practice using pedometers. Students will walk 264 feet, one-twentieth of a mile, while wearing a pedometer. They will
investigate if there is a significant difference between the number of steps recorded by a Dollar Store pedometer and a pedometer App.

Tutorial videos on cross sections of 3D objects along with interactive practice problems.

This is a unit length multi-learning style project that teaches the theorems and properties of Circles for the NC Math 3 curriculum. It includes hands on manipulatives using Exploragons, Digital Explorations in Geogebra, and a differentiating set of homework exercises through CK12.org.

Students will explore the equations of circles, their transformations, and derivation from the Pythagorean Theorem. Students will create circles on graph paper with specified center, radius, and containing 3 points. Students will determine the best location for a hospital to best serve the needs of Moore County.

In this lesson students will get to work with data for different countries that involve life expectancy and the number of people per television. This lesson focuses on students understanding correlation and causation, and that correlation does not imply causation. Previously, students would have had experiences with verbally and graphically exploring data and working with lines of best fit. The data in this example is older but still can provide for rich discussion and investigation.

Students will explore real data collected on the completion of a maze. Through the two-sample independent -test, students will test to see if the mean time to complete the maze is significantly different for males compared to females.

Students will continue their study of measurement geometry with a study of length of an arc and area of a sector

An introduction to piecewise functions using absolute value as a piecewise function of two linear functions.

Students compare periodic and continuous compounding and apply continuous compounding to a variety of problem situations.

In this article, students learn how to add or subtract two functions to create a new function.

This resource provides an explanation on adding and subtracting rational expressions and 50 practice questions with solutions.

Students will learn how to combine like terms from two functions or take the difference of two functions.

This lesson covers the concept that when given two equations in the same format, those equations can be added or subtracted.

This activity is similar to the idea of a function machine. There are two levels of the manipulative (called a nomograph). The first is comprised of two vertical number lines, input on the left and output on the right. The second has three number lines to accommodate displaying the composition of two functions. At the first level, students try to find the rule of a hidden function by entering domain values and observing how they are transformed to new (range) values. The transformation is illustrated dynamically by an arrow that connects a domain entry to its range value. At the second level, students investigate composite functions. Inverse functions are treated as special cases of composition.

Students perform a simulation to measure the sound intensity at different distances from the source of a noise, and then use the data to develop an inverse variation model.

In this lesson, students rewrite simple rational expressions in different forms, including representing remainders when dividing.

In this lesson, students use the distributive property to multiply a monomial by a polynomial and understand that factoring reverses the multiplication process. Students use polynomial expressions as side lengths of polygons and find area by multiplying. Students recognize patterns and formulate shortcuts for writing the expanded form of binomials whose expanded form is a perfect square or the difference of perfect squares.
