[Free Registration/Login may be required to access all resource tools.] This lesson covers using a graphing calculator and matrices to solve a system of equations.

Use this calculator to find values that satisfy the golden ratio where (A+B):A = A:B. Enter any ratio term to calculate the missing golden ratio values. The answer also includes two additional, equivalent sets of golden ratio terms based...

In this multi-day activity, 3rd graders make 3 different models of an orphanage floor plan using Google Drawing, Virtual Graph paper, and a construction of rectilinear shapes, to calculate the area of each room using units square.

Investigates how to graph the inverse of a function. There is also an explanation that involves the use of a graphing calculator.

This integrated lesson is the result of collaboration between Chip Blanton, a wildlife management teacher, and Greg Pendergrass, a math teacher (Ft. Payne High School). Learning to manage wildlife requires an understanding of planting...

Practice calculating the interquartile range from a set of data. Students are able to check their answers, view a solution, and watch a video or use a hint.

Use this prime numbers calculator to find all prime factors of a given integer number up to 1 trillion. This calculator presents prime factors of a number, prime decomposition in exponential form, CSV (comma separated values) list of...

Test your knowledge of coordinate geometry by taking this twenty question multiple-choice practice test. Use a graphing calculator to help with any graphing problems and check your answers at any given time throughout the test.

Students investigate how to simplify using the distributive property. The resource consists of lessons with examples, an expression simplifying calculator, and a worksheet to check for comprehension.

Use your spatial reasoning skills to calculate the surface area when given a 3D figure. This video focuses on a right rectangular prism and shows you how unit blocks can help you visualize, then calculate the surface area. This video was...

n this section we will discuss solving trig equations when the answer will (generally) require the use of a calculator (i.e. they aren't one of the standard angles). Note however, the process used here is identical to that for when the...

Test your knowledge of working with data by taking this twenty question multiple-choice practice test. Use a graphing calculator to help with any graphing problems and check your answers at any given time throughout the test.

Use a z-table to find the probability that a particular measurement is in a range. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Learn how to calculate percent as a rate per 100 in this video from KQED. In the accompanying classroom activity, students model percent with a 10 x 10 grid. After watching the video, they create a design or picture on a 10 x 10 grid,...

When given a table, equation or verbal description, students will solve one- and two-variable equations and inequalities using algebraic steps or graphing methods.

This applet allows users to study the nature of triangles and their area. It draws random triangles on a Cartesian coordinate system. The user can determine the area of the triangle using his or her preferred method. After the calculated...

In this lesson, students explore "real-life" resources that make use of literal equations (rewriting known formulas) to help make people's lives easier. Students will use Excel to design formulas that find a specific value like those...

[Free Registration/Login Required] In this activity, students use the geometry program GeoGebra to explore Cavalieri's Principle, specifically to investigate whether it applies when calculating the volume of oblique solids. Lesson...
