Summary
Chapter 7 of the Class 1 Maths NCERT textbook (Joyful Mathematics), "Lina's Family", introduces young learners to measurement concepts — comparing heights and lengths, using body measures like handspan and footspan, comparing weights, and estimating how much water different containers hold.
- Comparing Heights — Tall, Taller, Tallest — The chapter opens with Lina's family get-together and asks children to find the tallest and shortest member in the picture. Children practice comparing the heights of different family members using words like taller and shorter.
- Near and Far — Comparing Distances — Children look at a village scene showing Lina's hut, a shop, a school, and a school bus, then circle whether each landmark is nearest to or farthest from another. This builds early spatial reasoning about distance.
- Comparing Lengths and Sizes — Longest, Shortest, Thickest, Thinnest — A set of 'Let us Do' activities asks children to tick the longest, shortest, thickest, and thinnest object from pairs of pictures, and to draw objects longer or shorter than a given one.
- Measuring with Handspan and Footspan — Children learn to measure everyday objects — tables, bags, pencils, arms — using their handspan, and measure classroom distances using footspan. They guess first, then measure, comparing their guess to actual findings.
- Comparing Weights and Capacity of Containers — The chapter ends with activities on weight (ticking the heavier or lighter object) and capacity (counting how many jugs, glasses, or bowls fill a bucket), teaching children that different containers hold different amounts of water.
Key points & formulas

- 03The Statue of Unity, a statue of Sardar Vallabhbhai Patel in Gujarat, is mentioned as the tallest statue in the world.
- 04A handspan can be used to measure objects like a table, bag, pencil, or arm.
- 05Fingers are used to measure smaller objects that are shorter than a handspan.
- 06Footspan is used to measure longer distances such as the length of one side of a classroom.

Frequently asked questions
01Who is in Lina's family?
Lina lives in a village with her grandparents, parents, and her brother Shanbor. Her uncles, aunts, and cousins also live nearby.
02What does the chapter teach about comparing heights?
Children learn to identify and circle the tallest family member in a picture and draw a cap on the shortest one. They also answer questions about who is taller than Lina's mother but shorter than Lina's father.
03What is the Amazing Facts fact in this chapter?
The chapter mentions that the Statue of Unity, a statue of Sardar Vallabhbhai Patel located in Gujarat, India, is the tallest statue in the world.
04What is a handspan and how is it used in this chapter?
A handspan is the width of an open hand from the thumb to the little finger. Chitra uses her handspan to measure the length of a stick, table, pencil, and notebook.
05When should children use fingers instead of a handspan to measure?
Fingers are used for smaller objects that are shorter than a handspan, such as a spoon or a key.
06What is footspan and what is it used to measure?
A footspan is the length of one foot placed on the ground. Children use it to measure longer distances like the distance from their seat to the classroom door or the length of one side of the classroom.
07What activities does the chapter include about comparing lengths?
Children tick the longest and shortest objects from pairs of pictures, and also tick the thickest and thinnest objects. They also draw a stick longer than a given line and a rope shorter than a given line.
08How does the chapter introduce comparing distances?
Children look at a village picture showing Lina's house, a shop, a school, and a school bus, then circle whether each place is nearest to or farthest from another landmark.
09What weight activities are included in this chapter?
Children tick the heavier object or lighter object from pairs of pictures, and colour the heavier or lighter object in a set of four pictures. They also discuss how to find out who is heavier between themselves and a friend.
10What do children learn about capacity in this chapter?
Children count how many jugs, glasses, or bowls of water fill a bucket, and compare how many cups fill their water bottle versus a friend's bottle, learning which bottle holds more water.
11What water-saving ideas does the chapter discuss?
The Project Work section asks children to discuss why using a bucket for bathing saves more water than a shower or running tap, and talks about reusing water, closing taps when not in use, and giving leftover drinking water to plants.
12What is the Project Work activity about lengths?
Children tear and paste colourful paper strips to make one portion short and another longer, creating strips of different sizes to see short and long comparisons.
13How many handspans long is a typical table according to this chapter?
The chapter does not give a fixed number — children fill in the blank themselves after measuring their own table with their handspan, so the answer will vary for each child.
14What is the main maths topic of Chapter 7 in Joyful Mathematics Class 1?
The main topic is measurement — comparing heights, lengths, distances, weights, and the capacity of containers using simple, hands-on activities and body measures like handspan and footspan.
