  14. Coordinates Proper Names Learning Intention Success Criteria • Know the terms ‘origin’ , • x-axis and y-axis. • 1. To explain the proper mathematical names for various parts of the coordinate grid. • First number is always • x-coordinate and • second number is always the y-coordinate. www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  15. Coordinates Proper Names X Up Plot the point y - axis (4,3) 5 4 x-coordinate is 4 y-coordinate is 3 3 www.mathsrevision.com 2 (2,4) x-coordinate is 2 1 y-coordinate is 4 X 0 2 1 3 4 5 origin Along x - axis Created by Mr. Lafferty Maths Dept.

  16. Coordinates Proper Names Now try Exercise 4 Ch1 (page 6) www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  17. Starter Questions www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  18. Coordinates Extending the Grid Learning Intention Success Criteria • Identify main parts of coordinate grid. • 1. To show how we can extend the coordinate grid to include negative numbers. 2. Understand the negative grid both in y-axis direction and x-axis direction. www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  19. Coordinates Extending the Grid We can show we have gone below the axis by using a negative. Plot the point y - axis (4,3) 3 x-coordinate is 4 2 1 y-coordinate is 3 www.mathsrevision.com origin 0 2 1 3 4 5 x - axis -1 (2,-3) -2 x-coordinate is 2 -3 y-coordinate is -3 Write down coordinates of the other points Created by Mr. Lafferty Maths Dept.

  20. Coordinates Extending the Grid We can further extend the negative grid Plot the point y - axis (-2,2) 3 x-coordinate is -2 2 1 y-coordinate is 2 www.mathsrevision.com origin 0 -2 -3 -1 2 4 -4 1 3 x - axis -1 (-4,-2) -2 -3 x-coordinate is -4 y-coordinate is -2 Write down coordinates of the other points Created by Mr. Lafferty Maths Dept.
