MATH SECOND GRADE GRAPHING CATS DOGS FISH

2
There are many different kinds of graphs. This is a bar graph. It uses bars of color to show how many votes each type of movie received. This is a picture graph. It uses pictures to show how many votes each weather received.

3
This is a Line Plot. It uses a Number Line to record the data. TITLE

4
This is a picture graph. You may have filled out one of these on the first day of school. It uses pictures to show what you are voting for. In this graph each picture stands for only one vote

5
Every picture graph must have a title, the categories being voted about, a key, and the data or number of votes each category received. The key shows us that each picture stands for one vote. The scale also shows that each picture stands for 1. Where We Live HOME Key = 1

6
Now look at the same picture graph. What would happen if the key said that each picture stood for 2 votes. How many live in houses? ___ How many live in an apartment house? ___ How many live in a mobile home? ___ Always look at the KEY first! Where We Live HOME Key = 2

7
I have created a picture graph for you to label. Remember the labels that each graph should have: I did CATEGORIES and DATA for you. You add: TITLE KEY Now tell me about the graph.

8
This is a horizontal picture graph. Do you see how the categories are on the side instead of on the bottom? What should you at first? I hope you said the KEY! Each picture stands for 2 student votes. Discuss and compare the graph.

9
When the Key says that each picture is equal to more than 1you have to be very careful. Look at the half a box of pizza. What is the value of ½ a box? What about the picture of the little chicken? The KEY is the Key to every graph. How many votes did Pizza get? ___ How many votes did Chicken get? ___

10
What should you do first? ___________ How will the key help you count votes? What do you notice about the Double Fudge Brownies? __________ Which Dessert got the most votes? ________ Which got the least? _____

11
Did you notice that some of the picture graphs did not have a scale on the side? Would it help you to have a scale on each graph? HOW? _________________ _______________________ This graph has NO KEY! What do you think each picture stands for if there is no key? _____

12
This graph shows the number of children in each little town. Complete the graph and explain the data. Title - Key - Categories and Data Explain your data. __________ __________________________

13
REMEMBER: All graphs need a title. All bar graphs need a scale. All graphs need different categories of data. This is a bar graph. Bar graphs do not need a KEY! What does it use instead? ________ TITLE SCALE CATEGORIES OF DATA

14
This is a bar graph. Sometimes the bars go up and down. Sometimes the bars go across. If it has bars it is a bar graph. Does this bar graph have a title? Does this bar graph have a scale? Does this bar graph have different categories of data? Can you compare the data on this bar graph?

15
Let’s look at that bar graph again. What data does this graph show? Which season was the warmest? Which season was the coldest? What was the average temperature in Fall? _____ degrees F What is the difference between the average temperature in Summer and Winter? _____ degrees F

16
The last slide showed us a bar graph about the four seasons. Now you and your classmates will vote to show your favorite season. You will complete each graph below to show the same data. I started each bar graph for you. Title Categories of Data Categories of Data Scale ScaleScale SPRING 1 1 VERTICALVERTICAL HORIZONTAL

17
Now let’s look at this bar graph. Does it have everything labeled correctly? _____ How many kids had snakes? ___ How many kids had fish and turtles? ___ How many more kids had birds than snakes? ___ Which two pets got the same number of votes? ________________ How many total kids voted? ___

18
Now it is time for you and your classmates to share how many pets you have at your house. Give your graph a title, fill in the scale, and label the categories. You may make your graph horizontal or vertical.

19
Students took a survey to vote on their favorite color. How many students took this survey? ______ How many more students like the color red than green? ___ How many students like black and blue and pink? ___

20
Now it is your turn to show your favorite color. I have started the graph for you. Can you label the rest? Second Graders Favorite Colors

21
Sometimes it is easier to use a Tally Chart when you gather your data and then put your data into a graph later. Let’s make a Tally Chart about Ice Cream. I left some spaces empty so your class can add their favorite flavors. Now you just make a mark / for each student that votes for each flavor. Give it a try. FLAVORNUMBER OF VOTES VANILLA CHOCOLATE

22
What is the title? ____________ What was the total number of candies in this mini bag? _____ What is the scale? ___________ How many different colors were in this bag? _________________ How many more blue were there than green? _________________ How many orange and red? ___

23
What is the title? __________________ What two foods are tied? ___________ How many students took this survey? ___ How many more students picked hamburgers and tacos than picked pizza and salad? ___ How many fewer students picked hot dogs than pizza and salad? ___

24
Now it is your turn to take this survey with your class. After the bar graph is complete discuss the results. Watch out for the SCALE! FAVORITE FOODS PIZZA HAMBURGERHOT DOGTACOSALAD

25
Always look at the scale first. How many students took this survey? ______ How many more students picked soccer than picked basketball? ______ How many picked softball and soccer as their favorite sports? ______

26
Now it is your turn to take this survey with your class. After the bar graph is complete discuss the results. Watch out for the SCALE! FAVORITE SPORT SOCCER SOFTBALLFOOTBALLBASKETBALLOTHER

27
This is a combination picture graph and bar graph. Instead of using words in the categories they used pictures of each fruit. Which fruit was the favorite? __________ How many students took this survey? __________ How many more students picked bananas over pears? __________

28
Watch out for the scale! More students were born in which month? _________ Which month had the least births? __________ How many students were born in April and December and January? __________

29
Now it is your turn to create a BIRTHDAY BAR GRAPH. Give it a title. Give it a scale. I did the categories for you. Discuss and compare your data. JANFEBMARAPRMAYJUNJULAUGSEPTOCTNOVDEC

30
Picture graphs and Bar graphs are not the only kind of graphs you can make. Line Plots can also be used to show your data. This is a LINE PLOT graph. Line Plots use Xs to show a vote for a category. This graph shows that 13 students took this survey because there are 13 Xs. It shows that 2 students have Zero 0 brothers or sisters. It shows that 1 student has 4 brothers and sisters.

31
Many times it is easier to gather your data in a Tally Chart before you graph your data. Look at the Tally Chart. Did they graph their data correctly? Discuss and compare the data.

32
This Line Plot graph shows the ages of students at an after school program. It needs a Title! How many kids are 4 or less? ______ How many kids are 6 & 7? ______ How many kids are older than 8? ______

33
Line Plots are perfect to show numbers of things. This Line Plot shows the number of pets in each household. How many kids have more than 5 pets in their household? _____ How many took this survey? ____ How many more kids have 2 pets than have 13 pets? _____

34
The second graders are selling candy bars to earn money for their field trip. How many kids sold more than 5 candy bars? _____ How many sold less than 5 candy bars? _____ How many kids sold candy bars? _____

35

39
Now it is time for you to fill in a line plot. Remember that each X stands for 1 vote. You will need to add a Title and the data below in the Tally Chart. Worm LengthHow Many Worms 2 in/// 3 in/ 4 in//// 5 in 6 in//

40
Use the data in the Tally Chart to fill in the Line Plot graph. Remember that each X stands for only one vote. Day of WeekBooks Read by Class MONDAY// TUESDAY//// WEDNESDAY/ THURSDAY//// /// FRIDAY// SATURDAY SUNDAY////

41
Look carefully. I made mistakes when I entered my data into the Line Plot. Can you find my mistakes? Rope LengthHow Many 3 ft/// 4 ft/ 5 ft//// / 6 ft//// XXXXXX XXXXXXXX XXXXXXXX XXXXXXXXXXXX
