While it may seem incredibly obvious to the geometry student that congruent sides make congruent triangles, the proving of this by definition actually takes a bit of work. This exercise steps the class through this kind of proof by...

Two-variable equations can express a constant rate situation. The lesson presents several constant rate problems. Pupils use the stated constant rate to create a linear equation, find values in a table, and graph the points. The resource...

In this line segment worksheet, 10th graders identify and solve 10 different problems that include determining the midpoint of a line segment in each. First, they determine the midpoint of a segment that connects two points. Then,...

In this equations and inequalities worksheet, 9th graders solve and graph 10 different problems that include determining the slope of a line in each. First, they determine the line that contains given points on a grid. Then, students...

In this slope worksheet, 9th graders solve and complete 18 different problems that include identifying various points on a graph. First, they determine the slope of each line drawn on the grid to the right. Then, students determine the...

In this geometry skills worksheet, students examine a graph and respond to 5 questions that require them to identify the coordinate pairs of object on the grid.

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Enhance fourth graders' math vocabulary with 17 word cards and their definitions. Learners focus on terms that deal with graphing, such as y-axis, coordinates, plot, and ordered pair in the last set of math vocabulary cards. 

Middle schoolers find the area of three figure by the traditional formulaic methods. Then they count the number of grid squares to double check. They show an intuitive sense of Pick's Algorithm by counting every two boundary squares as...

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...

Middle and high schoolers explore the concept of slope. In this slope lesson, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid....

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Learners first create designs for greeting cards by applying transformations of shapes on a coordinate plane, and then determine a sequence of transformations that produces a given design.

A lesson involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

Do you need to graph lines to see the point? A thorough lesson plan provides comprehensive instruction focused on solving systems of equations by graphing. Resources include guided practice worksheet, skill practice worksheet,...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Fourth graders are introduced to how to properly create a grid site. In groups, they use Cartesian coordinates to establish the boundaries for the grid and photograph the location of artifacts. They exchange their photos with another...

Learners read and plot coordinates in all four quadrants and state where a shape will be after translation. They explore the concept of translation using a a four quadrant grid of the of River Tyne running through all 4 quads. In...

In this ordered pairs worksheet, 10th graders solve and graph 6 different sets of points on each graph. First, they draw each of the given ordered pairs in each problem on the gird shown. Then, students label each of these points on the...

Students comprehend the basic units of measurement, scale, plotting, and basic grids. Students practice their estimation and measuring skills and will demonstrate their ability to work well in groups.

Young scholars practice coordinates and measurements, develop 2D, 3D topological map, construct grid with string on real surface, establish "level" fixed point for measurements, take and record data points of elevation, and enter data on...

Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
