NCERT Revision Notes for Class 1 Maths Chapter 7: Lina’s Family – Free PDF Download

Chapter 7 of Class 1 Joyful Mathematics, Lina’s Family, uses the idea of a family to introduce early data handling skills — counting how many people or things belong to a group, comparing groups (more, less, equal), and organising simple information using pictures and tally-style counting.

Key Concepts

Collecting information: gathering simple facts, like how many members are in a family or how many people like a particular fruit.

Organising information: arranging collected facts neatly, such as listing family members or drawing one picture for each person counted.

Comparing groups: using the words “more”, “less”, “most”, and “fewest” to describe differences between groups after counting.

Simple picture representation: drawing one symbol (like a circle or a stick figure) for each item counted, an early step toward pictographs used in later classes.

Family relationships: understanding and naming close family members, such as mother, father, sister, brother, grandmother, and grandfather, and counting them as a group.

Worked Examples

Example 1

Lina’s family has a mother, a father, two sisters, and herself. How many people are in Lina’s family in total? Counting: mother (1), father (2), sister (3), sister (4), Lina (5). There are 5 people in Lina’s family.

Example 2

In a class, 6 children like mangoes and 4 children like grapes. Which fruit is liked by more children? Mangoes, because 6 is greater than 4.

Example 3

Draw one circle for each pet a family has: 3 dogs and 2 cats. This would be shown as three circles in one row and two circles in another, making it easy to compare at a glance.

Quick Recap

• Collecting and organising simple information is the first step in data handling.
• Drawing one picture or symbol for each item counted makes comparisons easy to see.
• Words like “more”, “less”, “most”, and “fewest” describe differences between counted groups.
• Family members can be counted just like any other group of objects.
• This chapter is an early step toward pictographs and bar graphs taught in later classes.

Common Mistakes to Avoid

• Forgetting to count oneself while counting the total number of family members.
• Drawing an unequal number of symbols compared to the actual count, which makes the picture inaccurate.
• Mixing up “more” and “less” when comparing two groups.
• Not lining up pictures neatly in rows, which makes it hard to compare groups at a glance.
• Counting a family member twice, especially when listing relationships like “mother’s mother” as a separate unfamiliar person.

Home Practice Tips

• Make a simple family list together and count the total number of members, including the child.
• Ask family members their favourite fruit, colour, or game, and draw one symbol for each answer to compare.
• Practise using “more”, “less”, “most”, and “fewest” while comparing everyday groups, like toys of different colours.
• Create a simple picture chart of pets or plants at home.
• Talk about family relationships and count family members from both the mother’s and father’s sides separately.

Frequently Asked Questions

Q1. Why does this chapter focus on “family” to teach data handling?
Family is a familiar and personal topic for young children, making it easier for them to understand the idea of counting, organising, and comparing groups of people or things.

Q2. What is the purpose of drawing one symbol for each item counted?
It creates a simple visual way to compare groups without needing to read numbers, which is an early step toward pictographs used in later classes.

Q3. How can I help my child understand “more” and “less” clearly?
Use two small groups of real objects, count each group together, and ask which group has more and which has less, repeating with different objects.

Q4. Does this chapter involve any calculations?
It mainly involves counting and comparing rather than addition or subtraction, though counting totals is part of the activity.

Q5. How does this chapter connect to later maths topics?
It builds the foundation for pictographs, tally marks, and bar graphs that children will learn to read and draw in higher classes.
