Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates.

20-30min – students use the Coordinate Drawer app to recreate and manipulate their designs and/or to create new designs.

If students are self-pacing, have two students swap as soon as they are ready to move on.

10-20min – Step 4: students swap second pages with a partner, and each attempts to follow the other’s algorithm by plotting the coordinate pairs and connecting them in order.

10-20min – Step 3: students identify and list all of the coordinate pairs needed to recreate their design, keeping in mind that the order each pair is connected in is critical to the algorithm.

5min – Step 2: students plot and connect coordinate pairs to recreate their design.

5-10min – Step 1: students brainstorm and create a shape using only straight lines.

Students can self-pace through this lesson, but you might suggest or loosely enforce the following chunks: Print the worksheet single-sided, such that students can share the second page independent of the first It is possible to run this activity without the app, if you do not have devices for students. If you are not using Chromebooks, you must use the web app.

Install Coordinate Drawer Chrome app on students’ Chromebooks (through Google Admin console), provide a link where they can install the Chrome app from, or provide a link to the web app. Coordinate Drawer Chrome app or Coordinate Drawer web app.

Understand that computers perform the exact series of steps we input, even if we meant something different.Create artistic designs by plotting and manipulating coordinate pairs.Students are effectively writing a simple algorithm with their series of ordered pairs, and they will begin to understand that the computer running their algorithm (whether it’s their partner or the web app) only understands the exact algorithm they’ve input. Primary CT concept: algorithmic thinking.Graphing coordinate pairs on the coordinate plane.Students then enter the same list of ordered pairs into the Coordinate Drawer web app and explore how changing points and reflections affect their designs.

They trade their list of coordinate pairs with a partner, who attempts to recreate the original image to see how accurate their algorithm was. Here’s another way to think about it.In the Drawing with Coordinates activity, students will create their own designs by plotting coordinate pairs on paper. Once you know about the quadrants in the coordinate plane, you can determine the quadrant of an ordered pair without even graphing it by looking at the chart above. Starting from the origin, go along the x-axis in a positive direction (right) and along the y-axis in a negative direction (down). Starting from the origin, go along the x-axis in a negative direction (left) and along the y-axis in a negative direction (down). Starting from the origin, go along the x-axis in a negative direction (left) and along the y-axis in a positive direction (up). Starting from the origin, go along the x-axis in a positive direction (right) and along the y-axis in a positive direction (up). They also follow a pattern, which is outlined in the table below. Within each quadrant, the signs of the x-coordinates and y-coordinates of each ordered pair are the same.
