Grade Level: 4th Skill: Graphs and Charts Topic: Answer Questions About Graphs Goal: Interpret one- and two-variable data graphs to answer questions about a situation. Skill Description: Read and find information about data that is represented on graphs (bar graphs, line graphs, circle graphs, etc.)

Building Blocks/Prerequisites

Sample Problems

 (1) What program do 3 year olds watch the most? _______________ (Dora the Explorer) (2) Line graph What was the difference in test scores from year 1 to year 7? (700-400 = 300 points) (3) Bar graph- About how many people were surveyed about their favorite foods? ______(about 272 people) (4) Circle graph: What types of books do students enjoy the least? _________ (Biographies) (5) Which type of graph should be used if you want to compare the amount of time animals sleep? ___________ (bar graph)

Learning Tips

 (1) How to choose an appropriate graph: Line graph- shows change over time; Use a line graph to show whether data increases or decreases. Bar graph- compares data. Use a bar graph to see how may of each type of item are in the data. Double bar graph- Compares 2 sets of data. You can compare how two items are represented in the data. Circle graph-shows how data as a whole is broken into different parts. Line plot- shows how many times each number occurs in the data Stem and leaf plot- shows data arranged by place value. Use the plot to organize a long list of numbers. (2) Design Graphs Materials: rulers, chart paper, pencils, markers, crayons Have child design graphs that relate to their daily lives. For example, Make circle graphs dividing up their day Make bar graphs comparing how much each person watches television It will help them be able to identify various types of graphs and understand why they are used. (3) Make survey questions and interpret their data into graphs. They can ask their friends some questions about: Favorite food, favorite video games, favorite books, etc. It will allow them to have fun while learning. (4) Review the parts of a graph: Title Headings for x and y-axes Intervals Scale Key (5) Research the internet and find various graphs that your child is studying. Have them organize the graphs making columns on chart paper and pasting the graph in the appropriate column that represents the graph.
