Complete answer key – NCERT solutions  

Going out with Grandfather!  
Explanation:
Children should observe the picture carefully, count the number of people, and share the activities they see happening in the park. They can also talk about how many children are playing at first and how many join later.  
Activities: Playing on swings, running, walking with grandparents, sitting on benches.  
Number of children: At first 4 children are playing, later 2 more join them, making 6 children altogether.  

Tell How many Altogether? Fill in the Blanks  
1. 4 + 2 = 6  
2. 3 + 1 = 4  
3. 3 + 2 = 5  
4. 4 + 3 = 7  
Explanation:
Addition means finding the total by putting objects together (combining two groups) or by adding more objects to a group and counting all.

Add and Draw  
1. 6 + 2 = 8  
2. 7 + 1 = 8  

Let Us Count  
A. Sample Answer: My parents together have 5 brothers and sisters.  
B. Sample Answe: We both have 10 family members altogether.  
C. 20 fingers  
D. 10 numbers  
Explanation:
Children should say the addition sentences aloud to connect the words "make" with the symbol (+) and "altogether" with the symbol (=), helping them understand the meaning of total and sum.

Count and write the total number of fingers  
1. 4 + 3 = 7  
2. 3 + 2 = 5  
3. 5 + 3 = 8  
4. 4 + 0 = 4  
5. 4 + 4 = 8  

Let us Play – Addition with Dice!  
Explanation: Roll two dice together, count the dots, and find the total. Compare scores with your friend to see who gets more.  

Let us Do  
A. Kishore = 6, Nitya = 5 → Kishore wins  
2. Kishore = 4, Nitya = 7 → Nitya wins  
3. Kishore = 5, Nitya = 8 → Nitya wins  
4. Kishore = 4, Nitya = 5 → Nitya wins  
5. Kishore = 6, Nitya = 7 → Nitya wins  

Beads and String

Explanation:
Children should colour the beads according to the given numbers, then count them to understand how addition works. This activity helps them visualize addition by combining two groups of beads to find the total.

Hop and colour the strip and write the sum in the given space.
1. 4 + 2 = 6  
2. 3 + 2 = 5  
3. 5 + 3 = 8  
4. 6 + 3 = 9  

Add in Your Own Way  
1. 2 + 3 = 5

3. 3 + 3 = 6  
4. 9 + 1 = 10  

Let us Do:
A.Fill up the number pairs.  

7 + 1 = 8  
1 + 7 = 8  
2 + 6 = 8  
6 + 2 = 8  
3 + 5 = 8

How Many Left?  
i. 6 frogs – 2 jumped away = 4 left  
ii. 7 balloons – 2 flew away = 5 left  
iii. 9 bananas – 6 taken away = 3 left  

Think and Do  
i. 3 pots – 1 broke = 2 left  
ii. 7 ladoos – 4 eaten = 3 left  
iii. 7 balls – 2 taken away = 5 left  

Answer the following questions.
i. Manisha had 9 bananas, ate 3 → 6 left  
ii. 8 butterflies – 5 flew away → 3 left  

How many dots are hidden and how many dots are visible  
Total dots = 10  
Hidden dots = 0, Visible dots = 10  
Hidden dots = 3, Visible dots = 7
Hidden dots = 5, Visible dots = 5  
Hidden dots = 6, Visible dots = 4  

Project Work 

Explanation:
Children should make a frame with 8 dots, then hide a few dots using their hands or a cloth. They count how many dots are hidden and how many are visible. This helps them see that the total always remains 8, and the numbers of hidden and visible dots form pairs that add up to 8.
Sample Answe:
Total dots = 8  
Hidden dots = 3  
Visible dots = 5  

Hop backwards on the number strip  
A. 9 – 3 = 6  
B. 7 – 4 = 3  

Do the subtraction in your own way  
A. 8 – 2 = 6  
B. 7 – 3 = 4  
C. 9 – 5 = 4  
D. 6 – 3 = 3  
E. 5 – 1 = 4  
F. 4 – 2 = 2
