Forget the formal explanation about the importance of bar graphs in everyday life. Because if you are old enough to understand it, you can read the bar graph clearly without requiring a definition of the bar graph. But, for kids who are just familiar with bar graphs, their brains have not been able to process it quickly without an explanation. So you can give an understanding of a bar graph is something that will continue to be used in everyday life. By explaining its function, bar graphs can be learned from a young age and kids can use them in the days ahead when grown up.
Teaching bar graphs can use the method by drawing closer to children. You can choose the sample data or topic in the bar graph that children like. After that, you can vote with the kids in the room. Then give an explanation of how the results of the vote are written in a bar graph. Because bar graphs are visuals that have titled details as an explanation, you can teach them the meaning of each detail.
There are three important things in the bar graph. Ideally, the bar graph has three titles that will make it easier for anyone who reads it. The first is the name of the graph. This is the main title of the topic discussed. The second is the title of the vertical axis. The third is the title of the horizontal axis. The vertical and horizontal axis titles in the bar graph function to complement the data. For example, if the title on the vertical axis is the number of female members in the class, the horizontal axis can provide data on the number of female members in the class. In essence, titles on the vertical and horizontal axes must have continuity.
If you are going to teach bar graphs in class, it would be better if you have a bar graph worksheet that every child in the classroom can have. When it comes to data, it is rather difficult to make data that can be converted into bar graphs. Therefore it would be better if you already have a worksheet bar graph that is ready to be shared with children. You can buy it at a bookstore that sells student worksheets that adjust the grade. This shop can be found around you and can also be found online.
