CBSE Class 2 Mathematics — NCERT Solutions

Note: The exact numbers depend on the picture provided in the textbook. Students should look at the beach picture carefully and count each type of object.

Method of counting: It is easier and faster to count objects in groups or bunches rather than one by one. For example, if coconuts are arranged in groups of 5, count 5, 10, 15… instead of 1, 2, 3, 4, 5, 6…

Sample answers (based on a typical beach picture):

• Coconuts: Count all coconuts visible on the trees and ground.
• Boats: Count all boats visible in the water.
• Children: Count all children visible on the beach.
• Oranges: Count all oranges visible at the stall.

Conclusion: Counting in groups or bunches is quicker and less likely to lead to mistakes than counting one by one.

Given: Each necklace has 10 shells.

Method: Look at the shop picture and count the number of necklaces displayed.

Answer: Students should count the necklaces in the picture and write the number in the blank.

(Example answer: There are 5 necklaces of shells with 10 shells in each necklace.)

Given: A drum is a cylinder shape — it has two flat circular faces and a curved surface.

Instruments similar in shape (cylinder) to a drum: Tabla and Dholak (both are cylindrical in shape).

Answer: Circle the tabla and dholak (or any cylindrical instrument shown in the picture).

Given: A matka (earthen pot) is similar to a sphere or a rounded/oval 3D shape.

Instruments similar in shape to a matka: Instruments that are round/sphere-like, such as a ghatam (clay pot drum).

Answer: Tick the instrument(s) that are round and sphere-like in shape (similar to a matka).

Given: A ginladi (abacus-like counting tool) is shown in the image.

Concept: Count all the beads on the ginladi carefully.

Answer: A standard ginladi used in Class 2 has 100 beads in total (arranged in rows of 10, with 10 rows).

There are 100 beads in the ginladi.

Given: Blank cards are placed on the ginladi at various positions.

Concept: Count the number of beads shown on each card position and write the corresponding number.

Working: Count the beads carefully for each blank card — each row of 10 beads represents a group of ten. Count tens and ones separately and write the two-digit number.

Answer: Write the number that matches the bead count on each blank card. (For example, if a card shows 3 full rows and 4 extra beads, write 34.) Students should fill in the numbers by counting the beads on their own ginladi.

Yes! We can see the shadow of our own body, a tree, a dog, a cow, and many other animals and objects around us. A shadow is formed when an object blocks light.

Given: A thread held tight between two hands in a horizontal (sleeping) position.

Concept: When a thread is pulled tight (taut) it does not bend or curve — it forms a straight line.

Answer: Yes, it is straight. A tightly held horizontal thread forms a Sleeping/Horizontal straight line.

Given: Each garland has 10 flowers.

We write the number of tens (garlands) and ones (extra flowers) and find the total.

(Note: Javed's and Zoha's values are read from the picture described in the chapter. Javed = 43 flowers, Zoha = 20 flowers.)

Given: We use a textbook as a non-standard unit of measurement.

Concept: We can measure length by placing the textbook end-to-end along the object and counting how many times it fits.

Note: Answers will vary for each student depending on the size of their textbook and the actual dimensions of the objects in their classroom. A sample answer is given below.

Final Answer: Students should place the textbook along each object, count carefully, and record both their estimate and the actual measurement.

Given: Number of bicycles = 4, wheels on each bicycle = 2.

Total wheels = $2 + 2 + 2 + 2 = 8$

We are adding 2 four times, so: $4 \times 2 = 8$

Total wheels = 8

Given: The 2023 calendar provided.

Concept: Count the dates in each month from the calendar.

Working:

• January ends on 31, March ends on 31, May ends on 31, July ends on 31, August ends on 31, October ends on 31, December ends on 31. So these months have 31 days each.
• February ends on 28 (as seen in the calendar — the last date is 28). So February has 28 days.
• April ends on 30, June ends on 30, September ends on 30, November ends on 30. So these months have 30 days each.

Answer:

Given: Money received from father = ₹40; Money left = ₹3

Concept: Money spent = Money received − Money left

Working:
$$₹40 - ₹3 = ₹37$$

You can also find it by counting up from ₹3 to ₹40:
$$₹3 + ₹37 = ₹40$$

Answer: You spent ₹37.

Note: The picture (img_1.png) cannot be seen directly. The solution below uses a typical/standard set of values used in NCERT Class 2 Data Handling for this activity. Adjust the numbers if your picture shows different counts.

Assumed data from the picture:

• Red = 6 children
• Green = 4 children
• Blue = 8 children
• Yellow = 5 children

Completed Table:

Step-by-step answers:

A. Compare all numbers: Red = 6, Green = 4, Blue = 8, Yellow = 5.
The largest number is 8 (Blue).
$$\text{Most liked colour} = \textbf{Blue}$$

B. The smallest number is 4 (Green).
$$\text{Least liked colour} = \textbf{Green}$$

C. Yellow = 5, Green = 4. Since $5 > 4$:
Yellow colour is liked more than Green.

D. Red = 6, Green = 4. Since $6 > 4$:
Red colour is liked more than green.

E. Green = 4, Yellow = 5. Since $4 < 5$:
Green colour is liked less than Yellow.
