What to Watch Out for When Drawing a Bar Graph
Have students understand that the information they see along the horizontal line in a bar graph shows how
many of something is in the data, and the the information along the vertical line shows the types or
categories of the data.
When they are drawing a bar graph, let students know that they cannot miss any squares between the
colored squares, and they must color the squares from left to right.
After students have finished coloring in the bar graph, have them compare the numbers at the end of each
bar in the bar graph and the numbers shown in the tally chart to check if they have colored the bar graph
correctly.
