Cartesian Coordinates Teacher Resources

As you introduce graphs and coordinate pairs, use this guided activity to get scholars started. They reference an example before recording number pairs to identify the location of 12 letters on a grid. Next, learners examine shapes on a...

Plot points around a wheel. Pupils use an interactive tool to plot a point using polar coordinates with the aid of a wheel. Scholars use the interactive to answer five questions to finish the lesson. The resource provides background...

A series of graphs are displayed with points plotted for time and position. A question is asked for each, requiring your class to view one axis and track its partner coordinate. A few examples are given to begin each section, and so this...

The instructor shows how to write the inverse of a relation. In a set of ordered pairs, she takes each pair of coordinates and flips the order, getting the inverse.

Use a table to find the solution set for an equation. Watch an instructor as she directs how to create ordered pairs using a given domain and check your answers using one of these ordered pairs. A practical video for anyone, student or...

Reinforce math vocabulary with a set of flash cards. Forty-eight cards offer boldly printed words, and their corresponding definition alongside an example with labels. Terms include absolute value, inverse operations, slope, and more! 

How well does the class understand dilations? The three-part assessment presents problems related to the properties of dilations. Pupils perform dilations and determine whether a dilation is responsible for a specific image.

Are all transformations of the plane linear transformations? The video provides examples of transformations of the plane and provides the definition of linear transformations. The resource begins the discussion of using matrix...

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...

What's the best way to dig a ditch? Scholars watch a video that shows the progress of ditch digging from two ends. Using coordinate geometry, they determine whether two ends will eventually connect to form one single ditch or not.

Examine dilation with matrices with your class. Learners write a conjecture for how the scale factor determines the size of an image. They then use their conjecture to write a matrix multiplication problem for the illustrated...

This engaging coordinate pairs activity will have scholars intrigued; they mark 13 points on a grid and then connect them to create a capital block letter. Which one will it be? The grid has whole numbers 0-10 along both axes, so...

Explore the mathematics of infection outbreaks with activities that ask learners to use coordinate grids to locate infected patients. They calculate amounts of ingredients for antidotes and determine which groups of people should be...

When is the distance formula not accurate? Referencing a map of the school, pairs determine the walking distance between two locations. Creating coordinates for each location, pupils determine the distance between the two points and...

Young scholars solve linear systems using slope intercept form. In this algebra instructional activity, students solve equations by rewriting them in the form y = mx + b. They evaluate coordinate pairs to see if they are a solution to...

This presentation is intended to accompany an entire unit and covers a wide variety of concepts. Counting on, counting back, symmetry, properties of 2-D shapes, completing symmetrical patterns, and measuring angles are all covered.

One way to solve a system of equations is to graph two equations and find the point of intersection. This method is demonstrated on a whiteboard to help your mathematicians understand the concept. An easy way to check your solution is...

Finding the domain and range of the inverse of a relation can be tricky, unless you know the correct steps! It's not that complicated. Watch this video and see how the instructor does the inverse of a relation before writing the domain...

This word problem has only one set of given numbers. How does one make a graph with only one set of numbers? Make a table to get the other set of values. Now these values make ordered pairs and can be plotted on a graph.

Discover the connection between vectors and translations. Through the activity, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then progress to the...

Everything the class knows about similarity in one small package. The last portion of a 16-part series is a three-question assessment. In it, pupils demonstrate their application of similar figures and their associated...

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

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...

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...
