1 Our Objectives Describe and find the position of a square on a grid of squares. Recognise simple examples of horizontal and vertical lines. Recognise positions and directions, e.g. describe and find the position of a point on a grid of squares where the lines are numbered.

5 X What is the position of this cross? (3,2) coordinates are always written in brackets, with a comma between each number the number on the horizontal axis is always written first, then the number on the vertical axis (0,0) is called the origin

6 Who can point to…… (7,3) X (3,7) (2,1) (1,2) (4,3) X X X X X (3,4)

7 Group1 Draw an 8 x 8 grid on squared paper. Plot the following coordinates on the board: (0,5), (2,3), (4,1), (5,0). Join the points with a ruler. What word do we use to describe the line youve drawn? Groups 2 and 3 Use the 8 x 8 grid. Plot the following coordinates on the board: (0,5), (2,3), (4,1), (5,0). Join the points with a ruler. What word do we use to describe the line youve drawn?

8 (0,5) (2,3) (4,1) (5,0) X X X X This is a diagonal line. What other points lie on this diagonal line? X X (3,2) (1,4)

9 Group1 Draw an 8 x 8 grid on squared paper. Plot 3 corners of a square. Give your grid to a friend. Can they tell you the coordinate for the last corner of the square? Do more squares. Groups 2 and 3 Use the 8 x 8 grid. Plot 3 corners of a square. Give your grid to a friend. Can they tell you the coordinate for the last corner of the square? Do more squares.

10 X X X What are these coordinates? (5,7) (2,4) (7,3) What shape would be drawn if these coordinates were joined together? A triangle!
