Pupils work together to create a 3D coordinate system. They plot points that are given to them and asked to find these points in space. They discover how engineers use coordinates in their careers.

Class members make a real connection to matrices in the 25th part of a series of 32 by looking at the identity matrix and making the connection to the multiplicative identity in the real numbers. Pupils explore different...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

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...

Young scholars research the history of the quilt in American History and view a PowerPoint Presentation. They create a quilt square with colored paper using polygons, transformations, rotations, and reflections on the computer and on a...

Third graders problem solve using drawings and map interpretations. They preview graphs and Cartesian geometry. They follow directions on a map using a grid and compass references while simulating they are reading a pirate map.

Students graph and solve linear system of equations. In this algebra lesson, students use algebraic and graphing methods to solve their systems. They find the point of intersection for their solution and draw inference from their data.

Students solve and graph linear equations. In this algebra lesson, students collect and plot data on a coordinate plane. They use the CBL and TI calculator to graph systems of equation.

In this algebra worksheet, students solve linear inequalities. They graph their solution on a coordinate plane. There are 6 questions with answer key.

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...

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. 

In this graphing quadratic inequalities instructional activity, learners graph eight quadratic inequalities.  Cartesian coordinate systems and solutions are provided.

In this linear and quadratic function instructional activity, students examine and solve a system of equations. They graph each function on a coordinate plane. This one-page instructional activity contains ten problems.

In this equations and graphing review instructional activity, learners write, graph and solve equations for 62 problems, including a mid-unit review, with answers included.

Students conduct Internet research to track the path of Hurricane Rita. They record the sea surface temperature of the Gulf of Mexico during and after the hurricane and draw conclusions about how hurricanes extract heat energy from the...

Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

Your young graphers will collaboratively play their way to a better understanding of the solution set produced by the combining of inequalities. Cooperation and communication are emphasized by the teacher asking questions to guide the...

Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Learners convert from one system of linear measure to another, graphing data from a table to a coordinate graph, using a graph to make predictions.

Students investigate using some of the basic skills of an archaeologist while using a Cartesian coordinate system. They establish a grid system for a dig site and determine the locations for different artifacts. Students use the...

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

High schoolers solve systems of equations. In this algebra lesson plan, students graph lines and identify the point of intersection. They identify the function to see if it is a function.

Teach your math lovers how to solve linear equations by graphing. Young scholars identify pairs of coordinates and use it to graph a line and use the TI to graph and observe the line.
