We first explored the coordinate plane in the 5th grade, but that was only dealing with positive coordinates. Now we know all about negative numbers so why not have negative coordinates as well? Let's get cozy with the x and y axis, plotting ordered pairs, quadrants, and reflection points. We got it covered. Sit back, relax, and get ready to groove with us. Common Core Standards: 6.NS.C.6, 6.NS.C.6b, 6.NS.C.6c, 6.NS.C.8
Let's get familiar with the x/y coordinate plane, both from the perspective of plotting points and interpreting the placement of points on a plane.
We're plotting an ordered pair on the x (horizontal) axis and y (vertical) axis of the coordinate plane.
Some of the given ordered pairs are already graphed on the coordinate pane in this example, but not all of them. Can you tell which haven't?
Practice plotting points using an xy coordinate system. The cooridnates of the points in these problems may be negative.
You like dividing up a pizza into slices? In geometry, we slice up the coordinate plane into quadrants. Although these are more like squares than triangular pizza slices! Let's learn about them.
This is a great exercise example in which we plot the ordered pair and then identify which quadrant the point lies. You'll get the hang of this quickly!
Practice graphing points and identifying which quadrants they're in.
In this word problem, we need to plot the ordered pairs and then figure out the difference in the y coodinate between the two. This will give us our answer!
Practice finding the distance between two points on the coordinate plane that share the same x- or y-coordinate.
Practice solving word problems by interpreting the meaning of points plotted on an xy coordinate system.
Just like looking at a mirror image of yourself, but flipped....a reflection point is the mirror point on the opposite axis. Watch this tutorial and reflect :)
Practice reflecting points across axes on the xy coordinate plane.
