Co-ordinate pairs

Learning Intention: create rules from sets of coordinate pairs

Diagnostic:

List 4 other tasks that make use of the coordinate pair skill (i.e. grid coordinates on a map)

Example:

Tasks:

1) Play 4 in a line with a partner (play at least 3 times)

    On a 6 by 6 grid, students take it in turns to mark a point. One is 'crosses' the other is 'noughts'. The first player to get four in a line next to each other (horizontally, vertically or diagonally) wins.

2) Record the co-ordinates of the winning lines:

3) Complete the following problems in your exercise book:

Link a simple interactive using x and y co-ordinates

Link to a Maze game to navigate around a grid using x and y coordinates without hitting the mines

Link to a Boat game where you control a boat using x and y coordinates

Link to a Scratch game of Battleships for 2 players using co-ordinates

Diagnostic answers:

Battleships, Supermarket aisles, identify chess moves, plotting points on a graph.

Answers

1) (1,2) x = 1

2) (5, 4) y = 4

3) (0, 4) x = 0

4) (2, 2) y = x

5) (3, 4) y = x + 1

6) (1, 2) y = -x +3

7) (4, 5) y = -x + 9

8) (2, 3) y = x + 1

9) (2,6) (3,5) (4,4) (5,3) 

10) (0,3), (1,4), (2, 5), (3, 6)
