Don't let your second grader forget graphs! Be sure to review how to read a bar graph and pictograph with help from this handy worksheet. Challenge your young mathematician to read the graphs and answer some questions.
Measurement and data in first grade includes such important concepts as comparing the length and weight of two objects using a third object. This guided lesson, designed by curriculum experts, takes students on an exploration of these measurement and data concepts. Once through with the lesson, kids can gain extra practice with measurement and data with the accompanying worksheets.
Learning how to represent numerical information is a key part of the third grade math curriculum. This lesson in data provides guided instruction designed by our team of curriculum experts and teachers to present this concept in an engaging way. Not only that, but helpful exercises help kids to see the practical applicaton of these skills in the real world.
A bar graph is a way to show data using bars of different heights and color. For young learners, this more visual way of seeing information is easier than reading a set of numbers or blocks of texts when trying to understand categories of data. With our resources and worksheets, your student will be an expert in interpreting data and identifying trends in data sets using bar graphs in no time.
Learn More About Bar Graphs
A bar graph, also known as a bar chart or a bar diagram, is a graphical display of data using bars of different heights. The bar can run horizontally or vertically, but the most important thing to remember is the longer the bar, the greater its value. A bar graph consists of two axes, the x-axis (which runs horizontally) and the y-axis (which runs vertically). One axis shows the specific categories being compared, and the other axis represents a measured value.
Three functions of a bar graph:
Compare sets of data between different groups at a glance
Show categories on one axis and a value in the other axis, with the goal of showing the relationship between the two axes
Show big changes in data over time
Three main types of bar graphs:
Vertical bar graph: The most common type of bar graph, in which data is displayed using vertical bars. The vertical bars have lengths that are proportional to quantities they represent. It is very useful when presenting a series of data over time.
Horizontal bar graph: A graph whose dependent variable is shown on the horizontal scale. The length of each bar is proportional to the quantity to be presented and all bars go across from left to right.
Stacked bar graph: Used to break down and compare parts of a whole. Each bar in the chart represents a whole, with segments representing different parts or categories of that whole. Different colors are used to illustrate the different categories in the bar.
There are many uses for bar graphs. Learning to read them will enable students to understand more complex series of information, and learning how to use them will allow students to categorize data more effectively.
