Sorting & Graphing a Collection

Note to Families
One of the mathematical topics we study in second grade is data analysis—collecting, graphing, and interpreting data. In this Home Connection, your child gets to organize and present information about one of his or her collections, or about a collection you have around the home. There are many sets of things that would work: rocks, shells, buttons, toy cars, stamps, books, cans of food, Legos, and so on. The only requirement is that there be 30 or more items in the collection and that there is enough variation in the items so they can be sorted in several different ways.

Sorting a Collection
Find a collection of some type around your home. It can be almost anything—rocks, shells, action figures, buttons, nuts and bolts, crayons, sports cards, etc. The collection you use for this assignment should have somewhere between 30 and 100 items. Once you’ve decided on your collection, work with someone in your family to sort it in as many ways as you can. List your ideas on the next page.

Here’s an example: Suppose I decide to sort my collection of toy cars. I could sort them by 2-door and 4-door, as I have in this picture. (I didn’t have room to show all 30!) I could also sort them by color, size, make, or type. See if you can think of at least 5 different ways to sort your collection.

Graphing a Collection
Look at all the ways you just sorted your collection. Now pick your favorite and make a graph about it on the back of this sheet. Here are some things to remember as you make your graph:

  1. You don’t have to mark all the columns if you don’t need them, but be sure to label each column that you use.
  2. If you have more than 10 items in any group, you’ll have to make your graphing boxes stand for more than 1. It’s okay to have each box stand for 2, 5, or even 10, depending on how many things you have to graph. Just remember to write your numbers in the boxes up the side so that we know how much each stands for.
  3. Be sure to give your graph a title so that we understand what it’s about.
