L.O Read and plot coordinates in all quadrants Geometry L.O Read and plot coordinates in all quadrants

What does the word coordinate mean? To coordinate means to do something in a set order. So coordinates are a way of ordering things exactly

Examples

Key words Quadrant Coordinates Any quarter of a plane divided by an x and y axis. Used to show a position on a coordinate plane or map shown as a pair of letters and/or numbers The first coordinate is the horizontal position (x axis) The second coordinate is the vertical position (y axis)

Examples Coordinates (4,2) - 4 in the horizontal and 2 in the vertical (x,y) - x is horizontal, y is the vertical

(1,6)= (3,2)= (1,3)= (5,3)= (6,0)= (1,4)= (0,2)=

The coordinate of the origin is (__,__) The origin is where the ___axis meets the ____axis The X axis, negative numbers, are to the ______ of the origin. The y axis, negative numbers are _____the origin.

Plotting coordinates A(4,5) B(-2,3) C(-5,-6) D(-4,3)

Questions (-2,3) (5,-5) A (3,0) B (-1,3) C (-3,1) Copy the grid on the left and then plot the points A (3,0) B (-1,3) C (-3,1) Plot a fourth point (D) in order to make a rectangle, and write down the coordinates of this point What are the coordinates of the blue dot, red dot and pink dot? (-2,3) Work out the coordinates of the other vertices (corners)? What is the length and width of this rectangle? (5,-5)

Questions (-2,3) (5,-5) A (3,0) B (-1,3) C (-3,1) Copy the grid on the left and then plot the points A (3,0) B (-1,3) C (-3,1) Plot a fourth point (D) in order to make a rectangle, and write down the coordinates of this point coordinates of the blue dot(4,3), red dot(3,-2) and pink dot(-3,-4) (-2,3) Work out the coordinates of the other vertices (corners)? (5,3) and (-2,-5) What is the length and width of this rectangle? 8 and 7 (5,-5)

Grid Lock First card is horizontal movement (x axis) Second card is vertical movement (y axis) Need to write down moves For example Ben (o) Mark (x) (3,4) (2,4) (-3,4) (1,6) Different versions- either first to get three in a row, or making rectangles and biggest area wins.

Plenary: These four points are the corners of a rectangle. (7,3) (-4,-1) How long are the sides of the rectangle? What are the coordinates of the remaining corner? What are the coordinates of the middle?
