1.)Engagement/Motivation Activity: After showing a large map of the city, the teacher will ask the students to explain how they would go about finding the location of the school. The teacher will allow for students to discuss ways to find the school by telling landmarks, following street signs, memorizing the roads, using a road map, etc.
2.)Step 1: The teacher will tell students they will be using coordinate points to help locate areas on a grid or map. The teacher will present a large coordinate graph on the white board.
Example:(See example in lesson attachment.)First, the teacher will review the terms ordered pair, x-axis, and y-axis by writing the following on the board:
Ordered pair - two coordinates that are used to find a point on a map or grid
x-axis – the horizontal axis
y-axis – the vertical axis
3.)Step 2: The teacher will begin by writing the ordered pairs (3,4) and (4,3) on the white board.
4.)Step 3: The teacher will demonstrate by plotting the point (3,4).
5.)Step 4: While demonstrating, the teacher will emphasize that the first number in an ordered pair represents a horizontal direction from 0. The second number represents a vertical direction from 0. Also, the teacher will tell students that the first number, x, is found first and the second number, y, is found second.
6.)Step 5: The teacher will then plot the point (4,3) by placing a sticker on this point. The teacher will use a marker to write the point (4,3) on the sticker.
7.)Step 6: The teacher will discuss with the students what was different about the directions moved to get to each point. The teacher will also ask students to brainstorm whether or not the final point would be different if we changed one of the numbers in the ordered pair.
8.)Step 7: The teacher will pass out the circle stickers to five students.
9.)Step 8: The teacher will then call out the following ordered pairs. The student who is holding the correct ordered pair should place their sticker correctly on the graph. Examples are 1. (8,3)
2. (12,5)
3. (5,3)
4. (9,9)
5. (3,8).
10.)Step 9: The teacher and students will discuss the placement of the stickers. The teacher should ask questions such as: What does each ordered pair represent?, How could we change the ordered pairs to have them mark a different point?, and What ordered pairs would allow us to land directly above each of these points we have marked on the graph?
11.)Step 10: The teacher will give out the What Am I? sheet and markers.
12.)Step 11: Together, the teacher and students will draw a straight line between the following points to reveal a picture. Examples can be found in lesson attachment.
13.)Step 12: The teacher and students will discuss their findings. The teacher will ask students to discover what ordered pairs could be provided in order to include a sun in the picture. The teacher should give all students a chance to come up with different ordered pairs that can be connected to draw a sun on the same page.
14.)Step 13: The teacher will pair students with a partner and instruct them to turn their desks facing one another. Students should be placed with someone who they will not act up with.
15.)Step 14: The teacher will tell students they will be playing the Battleship game, which includes points being called out to a partner. The teacher will pass out the Battleship game sheet.
16.)Step 15: The teacher will set up a divider (folder) between each of the pairs.
17.)Step 16: The teacher will give the students manipulatives (20 small squares).
18.)Step 17: The teacher will instruct students to use their squares and make 2 ships with each ship having 5 squares.
19.)Step 18: The teacher will explain to students 4 different ways to form their ships by drawing the following on the board. (Examples can be found in lesson attachment.)
20.)Step 19: The teacher will allow students time to form their ships.
21.)Step 20: The teacher will tell students that the first player will call out an ordered pair from (0,0) to (12,12). Their partner will look for those coordinates. Once found, he/she will remove the square lying there. The first player will draw a square on their graph to mark a piece of their partner’s ship. If the ship does not lie in the ordered pair, the partner will simply answer “no” and the first player will draw an X on that ordered pair to show that the ship does not lie there. The first person to call out all of the ordered pairs where a ship is located wins.
22.)Step 21: The teacher will assist students if any help is needed.
23.)Step 22: After the game has finished and discussion has taken place, the teacher will give students a copy of the Hartselle City map. Students will work in pairs to call out certain locations and allow their partner to find the location based on the coordinates given. Students will be able to locate 8 of out 10 coordinates correctly.
24.)Step 23: Lead a discussion about different ways to use maps. Have students discuss ways people in the community or outside of the community would use maps. Students can brainstorm different types of maps.
25.)Step 24: As an independent activity, with time permitting, take the students to the computer lab or where they will have internet access. Students will use the following website to practice with coordinate graphing. ( Coordinates) Students can choose from nine different games to play that will enable them to practice finding coordinates.
26.)Allow students to visit Google Earth where they can become more familiar with regions and maps. Students can explore finding different places.
27.)Allow students to visit Google Earth where they can become more familiar with regions and maps. Students can explore finding different places. (This should be downloaded and placed as an icon on the computer's desktop.)
