Information drives our society. Research studies promote consumer choices, social changes, government policies, technological developments and more. As educators, we need to prepare little minds for important data-driven futures. The tally chart is easy to use and understand, so it is an excellent choice for first-time researchers.
A tally chart is a simple means of recording small samples of categorical data in an organized way. The information gathered by a tally chart is to be separated into categories. Depending on the desired facts, categories might be favorite ice cream flavors, number of times you hear the word “cucumber” in a story, number of holidays in each of the twelve months, or shoe size. All kinds of information can be shown on a tally chart!
Storyboard That makes it super easy to create tally charts that can be used digitally or printed out and marked up in class. Print your tally chart on large format poster for class-wide charts, or print them on regular handout sized paper for students to use individually or in groups as they complete a task.
Making tally marks next to a category is much more efficient than listing items as they are reported.
Tally charts are very easy to make, and very easy to use! First, separate the space you are working with into rows and columns. On one side, or on top if preferred, we list our categories. If asking the question, "Where is your favorite place to read?", the categories would be the answers or options for that question.
Leave enough space to record the data as you discover it. An additional column for the frequency (number of instances of a specific data value) is often added for ease of reading after all the information has been collected. You will also hear tally charts referred to as Frequency Tables.
Students can get data through a survey, asking the same question(s) of different people, or by witnessing events over a period of time.
As you gather information, you make tally marks on your chart. For each response, we mark a single vertical line, like a lowercase letter “L”. When you reach the fifth data point, the notation changes slightly; instead of continuing to use vertical lines, every fifth data point is a diagonal slash across four vertical tally marks. It is an easy visual cue to see the data organized into groups of five. Have your students practice their skip-counting to get the totals for each category!
Students can count the tally marks individually if needed, but skip-counting by fives first makes finding the totals of each category quicker. Introducing skip counting by fives with tally charts demonstrates a very practical use for the skill to students. Students should record the totals for each category on the tally chart in a separate column for frequency.
Students are expected to be able to compare and answer questions about the frequency of data points. Many of these answers can be figured out easily by counting carefully, or by doing basic addition or subtraction with the frequency table.
Using the example below, have students interpret the following questions with the data presented!
By using language that students don’t necessarily associate with math, students will be able to see the value of gathering and analyzing the information.
Here are some questions that change up the language used, requiring students to analyze the data in a different way. Let these questions serve as inspiration for creating your own, unique storyboard tally charts!
The tally chart is the perfect tool for those who struggle with literacy, need to count quantities to recognize a number, or need assistance with arranging information.
Modified tally charts could be used to scaffold students with language or writing difficulties. Use pictures to pair with words (i.e., “dog” and the image of a dog) or simply use pictures or representations (splotch of red to indicate the category of “red”). Tally marks do not require much handwriting skill, and can be made with pencil, crayon, fingerprint, paper strips, objects, on paper, or in sand!
Use Storyboard That for creating and printing a tally chart for students to use as they survey classmates or make observations. Students can create their own tally charts on Storyboard That for printing to use for data-gathering, or as an electronic assessment for student understanding.
A tally chart is often the stepping stone between gathering information to displaying information in a graph. Use tally charts or a frequency table to prepare for bar graphs and other visual data displays!
