Learning how to read and create scaled bar graphs doesn’t need to feel like pulling teeth. Children can practice using small figures, working with addition within 5 resources and familiar objects to create manageable graphs. Start simple, such as tracking how many dogs they spot on a walk in the neighborhood or how many pieces of fruit they ate each day of the week.
Early learners tend to be visual learners. Teaching them to represent data in a visual way, using scaled picture graphs or scaled bar graphs, helps them to understand the whole data set as well as how subsets of the dataset relate to each other.
A scaled bar graph is a means of representing data in a two dimensional plane. The graph consists of two axes, a horizontal or X axis, and a vertical or Y axis. These axes represent the two aspects of the dataset students will represent on the graph. Each axis has a scale. The scale is the relation between the units that are being used to display the data and how they are represented on the graph; the distance between the marks on the axis.
Scaled bar graphs have their data displayed using bars or columns. Each column originates at 0 on the Y axis and at a specific place on the X axis. This may correspond to a number on the X axis or it could be in a category of data. The column will then rise vertically along the Y axis until it reaches the number that particular category or number on the X axis has attained.
Teachers should ensure that students are able to draw a scaled bar graph as well as answer simple “how many more” and “how many less” problems using the data in the scaled bar graph. Practicing interpreting scaled bar graphs using the resources provided by Education.com may help your students understand how to read them and understand what they represent.
