What Are Tally Marks in Math? Tally marks play an important role in mathematics. In probability, every question is requires having tally marks. It takes up a greater part of the probability concepts. They are an easy and quick method of keeping the track of numbers. Tally marks are marked in groups of five. It involves marking one vertical line for each number, stopping at the fourth number and the fifth number or line is represented by a diagonal line crossed across the previous four. Remember: It is to remember that every fifth mark has to be drawn across the previous 4 marks In case you are wondering, why do we use tally marks. Tally marks are an easy way to keep track of highly complex information in a systematic manner. When the data is complex and in large quantity, the observations are large, and it needs to be tracked, simply counting the frequencies may not be enough. So, we make use of Tally marks, also known as bass (/, |) to make complex data easy. A series of worksheets and lessons that introduce students to the concept of tally marks.

Lesson Sheets

What better way to start working with tallies than counting up a bunch of piglets?

  • Lesson 1 - Count the number of pigs. For each pig, make a tally mark by drawing a single, vertical line.



Practice Worksheets

The first 2 practice sheets come with extended explanations. I thought it was important to get students started off right.

  • Practice 1 - Use tally marks to show how many objects there are in the boxes. Then, circle the number that shows how many objects there are.
  • Practice 2 - If the count becomes greater than 4, then draw a diagonal line over the previous 4 vertical lines.
  • Practice 3 - The combination that you form this way is called a "unit:" this is a group of 5 objects.
  • Practice 4 - Count and use tally marks to show how many objects there are in the boxes.
  • Practice 5 - Match the correct number of objects with their corresponding tally marks, given on the right.
  • Practice 6 - A mix of all skills in one.
