While the activity focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can...

For this coordinate grid graphing worksheet, learners play a game of Battleship on the computer. They answer 21 questions about the coordinate grid and graphing.

Ninth graders describe latitude and longitude and how they may be useful to find things on a map.  In this cartography lesson plan students divide into groups and devise a coordinate system that can be used to communicate a...

In this Algebra I/Algebra II learning exercise, students solve systems of linear inequalities by graphing the inequalities on a coordinate plane and determining the location of all ordered pairs that solve the system.  The three...

A new, improved version of the game Battleship? Learners graph linear inequalities on the coordinate plane, then participate in a game where they have to guess coordinate points based on the solution to a system of linear...

Students view a polar view map and discuss ways of telling locations on the map. They view a copy of the map superimposed on a coordinate grid, then discuss ways of telling the locations. Students practice as a class and then...

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Where is the best place to work? Small groups map out a kitchen on a coordinate plane and find the centers of the work triangle to find the best place to install an island. The teams use algebraic methods to locate the center by finding...

Ever wonder how a butcher creates the different types of ground beef? Young mathematicians explore the methods butchers use to create their desired ground beef quality. Given a combination of two types of meat with varying...

Students solve systems of linear equations by graphing. The introduction of the lesson asks students to work in pairs or small groups to graph a line when given two points. Students graph 14 equations on the same coordinate grid to...

Students, working independently and in groups, apply the distance formula to practical situations. After solving various problems, students in pairs design coordinate planes from the school blue print to measure the distance from the...

In this algebra worksheet, students solve systems of equations using linear and quadratics. They graph their solutions on a coordinate plane. There are 5 questions with an answer key.

Learners work collaboratively to gain a better understanding of the vastness of space by scaling down the solar system. They measure by inches, gain an understanding of space, and model the distances of the planets from the sun.

Ninth graders know how to solve a system of linear equations, but what happens when the system involves an exponential function? The instructional slideshow teaches viewers to determine solutions to systems of equations with linear...

GPS is great for identifying your position, but is it finding your relative or absolute location? Ninth graders explore the difference between absolute and relative location, use the standard grid system coordinate system, and use GPS to...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Introduce your class to the federal tax system through an algebraic lens. This resource asks pupils to examine the variable structure of the tax system based on income. Young accountants use equations, expressions, and inequalities to...

A series of assessment tasks require learners to process information and communicate solutions. Topics include graphing parabolas, solving linear-quadratic systems, factoring polynomials, and solving polynomial equations. 

Perform data analysis on energy consumption to apply algebraic expressions to the real world. Learners will write and solve equations that answer various questions from residential power use. They will collect data at home and calculate...

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Young scholars address a major misconception in astronomy, the understanding of scale. The activity is designed to introduce students to both celestial coordinates and to the first rung on the distance determination ladder, parallax.

Pupils explore the Earth and its rotation. Volunteers model the sun-Earth system to demonstrate that the Earth rotates around the sun. In groups, students simulate "traveling" around the sun and discuss when it is night and day.

In this matrices and vectors learning exercise, students solve 9 various types of problems related to forming matrices and vectors. First, they set up each system of equations listed in matrix form using mathematical notation. Then,...

Students construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.
