This fun activity will allow students to explore several ways to sort and graph information according to certain attributes.
Introduction letter from Captain Graff: Dear Mr. E, I have enclosed a number of clues to a current case that we are working on. Please see what you and your assistant detectives can make of these items and get back with me. Thanks for your help with this, Your Friend, Captain Graff
Letter 1: Dear Mr. E and associates, I was just writing to check on the progress you have made on our top-secret case. I would love to see what you have come up with so I can compare it with what we were thinking here at the station. Please let me know what you have discovered as soon as possible. We are excited to hear from you. Your Friend, Captain Graff
Letter 2: Dear Mr. E and associates, Thank you for the helpful information you have sent to us. I was thinking about the same thing. I know that this case is not yet solved and would love to hear any other information you may have to help crack this case, I know we are close. Anxious to hear from you! Your Friend, Captain Graff
Letter 3: Dear Mr. E and Associates, Thank you for your help in solving our mystery. You truly have learned a lot about sorting information to be used to make a graph. I have another case that I need your help with. I am attending a family reunion and my son wanted to keep track of facts that he gathers from the reunion. Can you help us think of different facts that we could collect to share with his teacher for extra credit? I have included a book of the facts with this letter. Good luck! I am excited to hear from you all. Your Friend, Captain Graff
Letter 4: Dear Mr. E and Associates, WOW! You have all become such great detectives! Thank you for helping me solve the case. I have a huge caseload that has just come up and would love any help you can give me with this. I know that you are all first rate detectives, and that these cases will be solved with ease! Good Luck. Your Friend, Captain Graff
A graph is a tool that can show you things quickly. A graph uses pictures, shapes and colors instead of numbers to tell us how many of something there is. In Second grade students are responsible to use a variety of methods to organize, display, and label information, including keys, using pictographs, tallies, bar graphs, and organized tables.
In this lesson we will explore several ways to sort information according to certain attributes. We will then graph that information so we will understand quickly what we have sorted. Because of the versatility of graphs/data organizers being integrated in a multitude of other subject areas, this would serve as a valuable foundational lesson to teach at the beginning of the school year so that extension lessons can follow throughout the year.
5. Understand and use basic concepts and skills
Invitation to Learn
Write the graph title Todays lunch on the board. Then under the title write School lunch and Home Lunch, and have them line up behind the graph headings according to what they will be eating that day. Tell them they have just made a human bar graph. Record numbers on a piece of paper to refer to later and start on Instructional Procedures.
Sorting package contains several objects from each of the following categories: plants, animals, fantasy, reality, food, numbers, families, and communities where we live (urban, suburban, and rural).
Letter 3 arrives from Captain Graff thanking the class for their help with the mystery. Read the letter to the class.

Learning graphing skills benefits children in a variety of ways; it encourages an investigative spirit as questions are generated, conjectures are made, and relationships are discovered. Higher-level critical skills are involved and communications skills are reinforced as children discuss and write about their methods and discoveries. Graphing help children appreciate how useful math can be in the world outside the classroom.
