2. Hello! Today we will learn about Coordinate Grid and how to use it. Copyright © Ed2Net Learning, Inc.2

3. Coordinate Grid Copyright © Ed2Net Learning, Inc.3 Look at the calendar below.

4. From the calendar you can describe the position of a date.  For Example: What is the position of 17 on the calendar. You can see from the calendar that position of 17 on the calendar is fourth row and first column.  Here calendar is a grid. Copyright © Ed2Net Learning, Inc.4

5. Shown below is a grid.  You can use a grid to locate things. Copyright © Ed2Net Learning, Inc.5

6. For Example Copyright © Ed2Net Learning, Inc.6 Up Right Fairy tales History Nature Library

7. You can locate the position of different books by looking at the grid.  Books on nature are at 1right and 1 up.  History books are at 1 right and 3 up.  Fairy tales are at 3 right and 4 up. Copyright © Ed2Net Learning, Inc.7

8. Another Example: Copyright © Ed2Net Learning, Inc.8

9. From the grid of a class you can say  Ronnie sits at 1 right and 1 up.  Jacob sits at 2 right and 3 up.  Sarah sits at 3 right an 3 up. Copyright © Ed2Net Learning, Inc.9

10. Ordered Numbers An ordered pair of numbers is used to find the name points on the grid. (3,1) The first number shows how many places right. Copyright © Ed2Net Learning, Inc.10 The second number shows how many places up

11. For Example: Copyright © Ed2Net Learning, Inc.11 Cookies Doll Candies 1 2 3 4

12. From the grid we can describe the positions of the objects.  Doll is at (1,3) which means 1 square to the right and 3 squares up.  Candies are at (2,2)  Cookies are at (3,4) The ordered pair used to describe the position are known as Grid Coordinates. Copyright © Ed2Net Learning, Inc.12

13.  Another Example: Copyright © Ed2Net Learning, Inc.13 Wafers Teddy Candies 1 2 3 4

14. From the picture in the precious slide we can see:  The teddy is located at (1,3)  The wafers are located at (3,4)  The candies are located at (3,2) Copyright © Ed2Net Learning, Inc.14

15. Note:  In an ordered pair (3,4) is not equal to (4,3).  The first pair of coordinates mean 3 squares to the right and 4 squares up.  The second pair means 4 squares to the right and 3 squares up. Copyright © Ed2Net Learning, Inc.15

16.  An Example: Find the animals in the neighborhood: Rats are at (2,3) Cats at (3,2) Dogs at (2,2) Notice that (3, 2) is not the same as (2, 3). Both these positions have different animals. Copyright © Ed2Net Learning, Inc.16 Dogs Rats Cats 1 2 3 4

17. Now try this Tammy and his friends are standing in a grid shaped park. Give the location of:  Tammy (1, 1)  Susie (2, 3)  Barbara (3, 4) Give the location of Tammy if he moves two squares up. (1, 3) Copyright © Ed2Net Learning, Inc.17 Tammy Susie Barbara 1 2 3 4

19. Assessment Jude and his classmates are sitting in a grid shaped classroom. Give the location of:  Brandon (2, 1)  Jude (1, 4)  Archie (3, 4) Give the location of Brandon if he moves two squares up. (2, 3) Copyright © Ed2Net Learning, Inc.19 Brandon Jude Archie 1 2 3 4

20. Assessment Jamie and his friends are shopping in a grid shaped park. Give the location of:  Tammy (1, 1)  Susie (2, 3)  Barbara (3, 4) Give the location of Tammy if he moves two squares up. (1, 3) Copyright © Ed2Net Learning, Inc.20 Tammy Susie Barbara 1 2 3 4

21. Assessment Three rats Ricky, Lucky and Stucky are standing in a grid shaped room. Give the number of squares each will have to move to get to the cheese. Ricky (2 up), Lucky( 1 left, 1up), Stucky( 1 left, 1 down) Give the location of the cheese. (2, 3) Copyright © Ed2Net Learning, Inc.21 Ricky Cheese Stucky 1 2 3 4 Lucky

22. Assessment Hannah goes to her friend’s birthday party. The food is kept in a grid shaped room. Give the location of:  Strawberries (2, 2)  Tuna Sandwich (0, 3)  Hamburgers (3, 4) Give the number of Squares that she will have to move to get to the strawberries. (1 right, 1 up) Copyright © Ed2Net Learning, Inc.22 Hannah Tuna Sandwich Strawberry 1 2 3 4 Hamburger

23. Assessment Tracy and her friends are arranging her room which they have divided in a grid shape. What is located at:  (1, 1) (Table)  (1, 4) (Cupboard)  (3,3) (Bed)  (4,1) (Music Player) If the table is moved 1 square up and 2 right then give its new location (3, 2) Copyright © Ed2Net Learning, Inc.23 Table Bed cupboard Right UP Music Player
