Class 2 Maths Chapter 11 Revision Notes: Data Handling

Chapter type: Data handling — introduction to tally marks and simple data comparison.

Key ideas to remember:

Tally mark xe2x80x94 a single stroke recording one count; every fifth mark crosses the previous four for easy counting in fives.

Collecting data xe2x80x94 asking a question and recording each response.

Most/least xe2x80x94 comparing tally totals to find which option was chosen most often and which least often.

What you should be able to do after this chapter:

1. Record a count using tally marks correctly (grouping every fifth mark).
2. Read a set of tally marks to find the total count.
3. Compare tally totals to say which option is the most or least common.

Remember: Counting tally marks in groups of five (rather than one at a time) is much faster and less error-prone — always look for the crossed groups of five first, then add any leftover single strokes.

Frequently Asked Questions

Is data handling only about tally marks?
In this chapter, yes — tally marks and simple picture data are the two ways data is recorded and read; graphs and charts come in later classes.

How does this chapter connect to later classes?
It is the earliest step toward pictographs and bar graphs, which appear in Class 3 and beyond.
