![]() ![]() Students love to see their names displayed! The finished products make great classroom decorations. This is a challenging, but fun activity that middle school students really enjoy. Sample student name plotted and colored ("Davis") Sample block letter alphabet for student referenceĦ. Coordinate grid with 4 quadrants, x- and y-axes drawn and numberedĥ. Blank coordinate grid, 30 units x 40 unitsĤ. Student instructions for "Your Name In Coordinates" activityģ. Sample coordinate grid picture (the word "Graph") and corresponding coordinate pair instructions (for whole class review)Ģ. The challenge lies in writing the corresponding coordinate pairs, in order, so that another student can make a copy of the name.ġ. A sample block letter alphabet is included for reference. ![]() This personalizes the assignment as the students draw their own names and the names of other students using line segments. Pictures of letters are used in this unique graphing activity. In this activity, each student draws a picture of his/her name on a coordinate grid and develops a set of coordinate pair directions so that someone else can replicate the drawing. Kids love having their "15 minutes of fame!" Excellent coordinate grid practice any time of the year, but, if used at the beginning of the year, it's a fun way for students to learn the names of some of their classmates. ![]() Likewise, if a point intersects the vertical or y-axis, it is called the y -intercept.Personalized coordinate grid plotting activity with the students' names used as the "mystery" pictures. If a point intersects the horizontal or x-axis, it is called the x-intercept. the point of a graph that is on the x-axis or y-axis) are called intercepts. Points where a graph intersects the horizontal or vertical axes (i.e. For example, the coordinates \((3,4)\) and \((4,3)\) correspond to two different points! (Exercise: Plot these two points to see the difference.) Tip: Make sure to double check the order in which you write coordinates! The x-coordinate always comes before the y-coordinate. Plotting multiple points associated with ordered pairs creates the foundation of graphing using a (rectangular/Cartesian) coordinate system. The following diagram demonstrates what some points look like on the Cartesian/xy-plane. We can label points by writing its "name" before the coordinates, for example the point \(P\) at the coordinates \((0,3)\) can be denoted as \(P(0,3)\). Then move x units right or left, depending on whether the x-coordinate is positive or negative, and move y units up or down, depending on whether the y-coordinate is positive or negative. To plot a point associated with a coordinate on the Cartesian plane, start at the origin which has the coordinates (0,0). The first value, \(x\), is commonly called the x-coordinate, and the second value, \(y\) is called the y-coordinate. Every point on a coordinate plane can be associated with a unique ordered pair of real numbers, usually \((x,y)\), also called coordinates.
