Each student will use ordered pairs to graph a fish indigenous to Florida.
The student identifies and plots positive ordered pairs (whole numbers) in a rectangular coordinate system (graph).
The student knows how to identify, locate, and plot ordered pairs of whole numbers on a graph.
-Cm graph paper
-Colored and regular pencils
-Coloring sheet of Queen Angelfish
-Transparancy of cm graph paper and markers
-Color photo of a Queen Angelfish
1. Download copies of the Queen Angelfish coloring page from www.state.fl.us/fwc/.
2. Make a copy of cm graph paper for use as a transparency.
3. Find a photo of the Queen Angelfish.
4. Gather other materials.
1. Distribute graph paper and review the use of ordered pairs.
2. Use the transparency of cm graph paper, overhead, markers, and ruler to demonstrate the construction of a graph w/ a horizontal and vertical axis. The horizontal axis should be 20 cm long. The vertical axis should be 15 cm high. Instruct the students to copy your example.
3. Tell the students they will use a set of ordered pairs to graph the outline of a Florida animal.
4. Instruct them to make a list of the following ordered pairs with the label for each point:
5. Have the students graph and label each point. Using the ruler to make their connections straight, instruct them to connect -A- to -B- and so on . When they reach- ‘T- it should be connected to -A.-
6. At this juncture the students should be able to tell that the outline is a fish. Pass out the copies of the Queen Angelfish coloring page from the Florida Fish and Wildlife Conservation Commission. Also share the color photo of the fish. Instruct students to add detail to and color the outline they graphed.
Mastery or nonmastery will depend on whether students fully construct an ordered pairs graph by graphing and labeling correctly each of the ordered pairs. Students should correctly graph 16 of 20 ordered pairs.
Students may write their own set of ordered pairs to make their own outline of a Florida animal.
