Show the children a box with several cubes of different colors. Ask them for which color are there the most cubes. Then show them a bar graph or picture graph representing the number of cubes of each color. By looking at a bar graph or picture graph, they can quickly and easily see which color has the most or least cubes. Lead them to see that a graph allows you to find information fast. • How are bar graphs different from picture graphs? Picture graphs use actual pictures to show information. Bar graphs use symbols, colored blocks on a grid, to show the results. In order to read picture graphs, you must count the number of pictures; in bar graphs you simply need to read the number where the bar ends for each category. • When should I use a tally chart? We use a tally chart to collect data. Let’s say you want to know the mo
