Graphing day one Objective: I can formulate and answer questions by interpreting and analyzing displays of data, including multi-bar graphs or double line graphs..
There are many different types of graphs. pie graph/ circle graph bar graph - single or double frequency tables venn diagrams Tally charts line graphs TRY TO LIST AS MANY AS YOU CAN ON YOUR SLATES DID YOU HAVE ANY MORE??
Back to the basics - tally charts HOW MANY STUDENTS HAVE FRECKLES? 4! HOW MANY STUDENTS DO NOT HAVE FRECKLES? 8!
Vocabulary The new thing you need to know about tally charts it the word frequency FREQUENCY IS SIMPLY CHANGING THE TALLIES TO A NUMBER THIS NUMBER CAN THEN BE USED TO MAKE MANY DIFFERENT TYPES OF GRAPHS
Bar graphs WHAT CAN you TELL ME ABOUT THIS BAR GRAPH?? I have the kids come up and write in what they know on the lines
What about double bar graphs??? out of football, basketball, soccer, and tennis... write your favorite on your slate (pick one!!) FOOTBALL BASKETBALL SOCCER TENNIS FOOTBALL BASKETBALL SOCCER TENNIS 14 12 10 8 6 4 2 0 I take data from the students and from their data, we make the bar graph on the board
What about double bar graphs??? Now show me those slates again for a double bar graph Boys FOOTBALL ____ BASKETBALL____ SOCCER____ TENNIS____ FOOTBALL BASKETBALL SOCCER TENNIS 14 12 10 8 6 4 2 0 Girls FOOTBALL____ BASKETBALL____ SOCCER____ TENNIS____
Question Time IS MORE TIME SPENT WATCHING TELEVISION IN 3RD GRADE OR IN 4TH GRADE? HERE IS 3RD GRADE... AT 120 MINUTES PER DAY HERE IS 4TH GRADE... AT 60 MINUTES PER DAY MORE TIME IS SPENT WATCHING TV IN 3RD GRADE!

partner Time HOW MUCH more TIME DOES 6TH GRADE SPEND ON HOMEWORK THAN 4TH GRADE? 6TH = 90 MINUTES 4TH = 60 MINUTES 90 - 60 = 30 more minutes
Double bar graphs are not more work.... They just require reading the questions very carefully SO READ.... RE-READ.... FIGURE OUT WHAT THEY ARE ASKING YOU... THEN SOLVE!!
Slate time: answer the following questions on your slates 1. WHICH CLASS HAS THE MOST MALE STUDENTS? ROOM 302 2. WHICH CLASS HAS MORE GIRLS THAN BOYS? ROOM 303 3. HOW MANY MORE BOYS DOES ROOM 302 HAVE THAN ROOM 303? 3 MORE BOYS
4. WHICH ROOM HAS THE BIGGEST DIFFERENCE BETWEEN BOYS AND GIRLS? ROOM 301 5. WHICH CLASS HAS THE MOST STUDENTS ALL TOGETHER? ROOM 302 6. HOW MANY LESS GIRLS DOES ROOM 301 HAVE THAN ROOM 303? 4 LESS GIRLS * CHALLENGE: HOW MANY MORE BOYS ARE THERE THAN GIRLS IN ALL OF 5TH GRADE? 7 MORE BOYS
closure On your slate, describe the main difference between single bar graphs and double bar graphs SINGLE BAR GRAPHS DOUBLE BAR GRAPHS
