Understanding Tally Marks
Tally marks are a simple counting system often used to keep track of numbers in an organized manner. They are particularly useful in classrooms and for quick counting during activities.
Structure of Tally Marks
- Tally marks are represented by vertical lines.
- Every group of five is represented as four vertical lines with a diagonal line crossing them.
Why Does the Diagonal Line Represent Five?
- When counting, the first four tallies are made with vertical lines (| | | |).
- The fifth tally is then represented by drawing a diagonal line (/) across these four lines.
Count Representation
- The first four vertical lines represent counts of one each:
- 1st line: 1
- 2nd line: 2
- 3rd line: 3
- 4th line: 4
- The diagonal line signifies the completion of a group of five, not an addition to the count of four.
Conclusion
Thus, when you see four vertical lines crossed by a diagonal line, it clearly indicates a count of five (not ten, four, or one). Therefore, the correct answer to the question is option 'B' – a count of five. This method enhances clarity and efficiency in counting, making it a popular choice for quick tallies.

Understanding Line Graphs
Line graphs are powerful tools for visualizing data over time. They primarily help in identifying trends and fluctuations within the data, making them essential for various analyses.
Key Features of Line Graphs
- Visual Representation: A line graph displays data points connected by straight lines, which makes it easy to see changes over a specified period.
- Time Series Analysis: By plotting data against time on the horizontal axis, line graphs allow observers to track how values rise or fall at different intervals.
Fluctuations and Trends
- Identifying Trends: The primary advantage of line graphs is their ability to illustrate long-term trends. For example, a steadily rising line indicates growth, while a declining line suggests a decrease.
- Spotting Fluctuations: Line graphs can also highlight fluctuations, such as seasonal changes or sudden spikes and drops in data. This visual representation helps in understanding the data's behavior over time.
Comparative Analysis
- Multiple Data Sets: Line graphs can compare more than one dataset simultaneously. By using different colored lines, it becomes easier to see how different variables interact or relate over the same time period.
- Making Predictions: Recognizing trends in a line graph can also aid in forecasting future outcomes based on historical data, which is valuable for decision-making in various fields.
In summary, line graphs are excellent for identifying fluctuations and trends in data over time, making option 'B' the correct answer. They provide a clear visual summary that helps in understanding complex data easily.

Glitz Classes answered |
Tally marks are a simple counting method where each count is represented by a vertical line. For every fifth item, a diagonal line is drawn across four vertical lines to create a group of five. This grouping makes it easier to count large quantities quickly and accurately, as it visually organizes the data.
