Help your classes see the Cartesian plane for the map that it is! A video presentation describes the quadrants of the coordinate plane and how they affect the values of x and y. The instructor presents several examples of graphing...

The order in ordered pairs is an important descriptor! Young scholars learn how the order of a coordinate pair helps them find its location on a Cartesian plane. The video lesson demonstrates graphing points in each quadrant and explains...

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...

What does a grid have to do with area? Well, just about everything! Learners view composite shapes on a grid and watch as the video instructor finds their areas. The examples use shapes composed of rectangles and triangles. Scholars...

You'll be ready to plot something after a lesson on coordinate geometry! The video instructor begins by discussing how to plot four points to create a quadrilateral. The second example demonstrates finding the area and perimeter from the...

Get to the point of planes using an informative video lesson. A thorough lesson describes the components of the coordinate plane including the axes, quadrants, and origin. The facilitator then teaches the process of plotting and...

Change places by pivoting the figure. The section of a geometry playlist introduces rotations by making the connection to rotational symmetry. The presentation provides formulas to use with the coordinates when rotating a figure around...

Develop a prime example of sliding about the coordinate plane. Using figures on the coordinate plane, a segment of an extensive geometry playlist introduces the transformation of translations. The presentation uses coordinate notation to...

Coordinate the classification of quadrilaterals. Given the definitions of special quadrilaterals, a portion of a geometry playlist highlights ways to classify a quadrilateral. The video takes information from figures on a coordinate...

Multiply coordinates to either shrink or enlarge a figure. An informative segment of a geometry playlist introduces dilation on the coordinate plane. The dilations in the resource use the origin as the center of dilation, which makes...

Point out an application of Pythagoras. The segment of an essential playlist on geometry provides a quick review of the Pythagorean Theorem. Using a right triangle to show the positions of two points, the presenter calculates the...

Get the slope right with two easy steps. By placing two perpendicular lines on the coordinate plane, the video determines the relationship of the slopes of the two line lines. The resource is a part of an informative and extensive...

Discover the parallel structure of parallel lines. Provided with two parallel lines on a coordinate plane, the presenter shows that the rise and run, or slope, of the two lines are the same. The resource, which is a portion of a larger...

Rise and run to find slope. Given a graph of a line, the presentation shows how to find the slope by determining the rise and the run. The resource, part of an extensive geometry playlist, reveals the four basic slopes of lines.

Axis, coordinates, quadrants, oh my! Review graphing vocabulary with your classes with a quick video lesson. The instructor explains the vocabulary and provides problems for learners to try as they watch.

Graphing points is like painting a picture in algebra. Starting with a number line, the video constructs the coordinate plane. The presentation introduces the concept of a coordinate pair as an intersection of the two lines containing...

Take a look at vectors as geometric objects and then as an algebraic concept. The second video in a series of 15 introduces the vector using three perspectives: the physics, computer science, and mathematical. The resource shows the...
