# Creating Bar Graphs

Real-life scientists use charts and graphs as a way to organize and understand the information they have gathered. Young scientists can do the same! These activities will help you and your child create simple bar charts together, learn the vocabulary of graphing, and have fun building graphs using real objects.

One way to stimulate young minds is by creating and displaying information in chart and graph form. By creating simple bar or line graphs, children learn to ask questions and gather information about themselves and their surroundings. They also learn to sort and organize objects based on information. Last, young children can represent this information using real objects, pictures, and graphs.

Bar graphs are simple graphs in which the height of each bar provides information. Bar graphs use a few vocabulary words that help us understand the information in the graph.

• The graph title helps us know what information we can find on the graph. The graph title is usually found at the top of the graph. Our sample bar graph’s title is Favorite Cereal.
• The axes are the two sides of the graph. The vertical axis runs goes from top to bottom. The horizontal axis runs along the bottom of the graph.
• The axes labels tell us what information is presented on each axis. In our sample graph, one axis is Type of Cereal. The other is Number of Votes.
• The scale tells us how many or how much. In our example, the scale uses the numbers 1, 2, 3.
• The bar height tells us the value of each option. In our example, the height of the bars tells us how many people voted for each cereal.

Young children will love to create graphs based on all sorts of information. Some examples of graphs to create include: number of socks by color, favorite ice cream flavor, number of teeth lost, favorite thing to have for lunch.

As an alternative to paper-based graphs, have children use a large sheet of paper. Draw some simple grid lines, and ask children to real objects, rather than a drawn bar, to display the information. For example, have your child lay out their socks by color, or line up bowls to show favorite foods.

Graphs are widely used in math and science. Helping your child learn how to gather, organize, and share information using a graph is a great way to prepare them for success in school.
