8 What about double bar graphs??? I take data from the students and from their data, we make the bar graph on the boardWhat about double bar graphs???out of football, basketball, soccer, and tennis... write your favorite on your slate (pick one!!)1412108642FOOTBALLBASKETBALLSOCCERTENNISFOOTBALL BASKETBALL SOCCER TENNIS
9 WHAT CAN you TELL ME ABOUT THIS BAR GRAPH?? I have the kids come up and write in what they know on the linesBar graphsWHAT CAN you TELL ME ABOUT THIS BAR GRAPH??
