Chapter Solutions
1 Tell How Many Altogether? (Page 49-50)
🎮 Teaching Concept:
Connecting the word "altogether" and "make" with the addition symbol (+) and the equals symbol (=). For example, "4 children and 2 children altogether make 6 children" is written as "4 + 2 = 6".
Fill in the Blanks (Page 49):
4 children and 2 children altogether make 6 children.
4 + 2 = 6
3 tops and 1 top altogether make 4 tops.
3 + 1 = 4
3 ants and 2 ants altogether make 5 ants.
3 + 2 = 5
4 pencils and 3 pencils altogether make 7 pencils.
4 + 3 = 7
Add and Draw (Page 50):
6 balls and 2 balls altogether make 8 balls.
6 + 2 = 8
Children should draw 8 balls.
7 balls and 1 ball altogether make 8 balls.
7 + 1 = 8
2 Count Fingers and Addition with Dice! (Page 51)
Count and write the total number of fingers.
🎲 Let us Play - Addition with Dice:
Roll two dice together and count all the dots to find the total sum. (e.g., If you roll a 3 and a 4, the total is 7).
3 Score Board Game - Kishore vs. Nitya (Page 52)
Add the dots on the dice to see who scored more points.
| Round | Kishore's Dice & Score | Nitya's Dice & Score | Winner |
|---|---|---|---|
| A | 5 and 1 = 6 | 4 and 1 = 5 | Kishore (✓) |
| B | 2 and 2 = 4 | 1 and 4 = 5 | Nitya (✓) |
| C | 1 and 4 = 5 | 4 and 4 = 8 | Nitya (✓) |
| D | 3 and 1 = 4 | 2 and 3 = 5 | Nitya (✓) |
| E | 4 and 2 = 6 | 4 and 3 = 7 | Nitya (✓) |
Overall Winner: Nitya!
4 Addition with Beads and Number Strip (Pages 53-54)
Page 53: Beads and String (Find the total number of coloured beads).
Children color the respective number of beads in the book.
Page 54: Hop and Find the Sum (Number Strip/Line)
4 + 2 = 6 (Start at 4, hop forward 2 spaces, land on 6)
3 + 2 = 5 (Start at 3, hop forward 2 spaces, land on 5)
5 + 3 = 8 (Start at 5, hop forward 3 spaces, land on 8)
6 + 3 = 9 (Start at 6, hop forward 3 spaces, land on 9)
5 Add in Your Own Way & Grouping (Pages 55-56)
Page 55: Abdul and Rihana are adding in different ways (Vertical & Horizontal).
Page 56: A. Fill up the number pairs (Making 8 and 7).
Pairs that make 8
- 7 + 1 = 8
- 1 + 7 = 8
- 5 + 3 = 8
- 2 + 6 = 8
- 4 + 4 = 8 (Missing bubble)
- 3 + 5 = 8
- 6 + 2 = 8 (Missing bubble)
Pairs that make 7
- 6 + 1 = 7
- 1 + 6 = 7
- 5 + 2 = 7
- 2 + 5 = 7 (Missing bubble)
- 3 + 4 = 7 (Missing bubble)
- 4 + 3 = 7 (Missing bubble)
Page 56: B. Add and match the following (Sums to 9, 6, 7, 5)
- Match to 9: 2 + 7, 1 + 8, 6 + 3, 0 + 9, 5 + 4
- Match to 6: 4 + 2
- Match to 7: 5 + 2, 3 + 4
- Match to 5: 1 + 4, 3 + 2
6 Subtraction - How Many Left? (Pages 58-61)
🎮 Teaching Concept:
Introducing the concept of subtraction using terms like "left", "flew away", "took away", and "steps out". Connecting this to the minus symbol (-).
Page 60: A. Fill in the blanks (How Many Left?)
6 frogs, 2 jumped away. 4 left. ➔ 6 - 2 = 4
7 balloons, 2 flew away. 5 left. ➔ 7 - 2 = 5
9 bananas, 6 taken away by elephant. 3 left. ➔ 9 - 6 = 3
Page 61: B. Draw the objects that are being left and fill in the blanks.
i. 3 pots, 1 pot broke. 2 left. ➔ 3 - 1 = 2
ii. 7 laddoos, 4 eaten. 3 left. ➔ 7 - 4 = 3
iii. 7 balls, 3 took away. 4 left. ➔ 7 - 3 = 4
Page 61: C. Answer the following questions (Word Problems).
i. Manisha has 9 bananas. She ate 3 bananas. How many bananas are left?
Answer: 9 - 3 = 6 bananas left.
ii. There are 8 butterflies on the flowers. 5 butterflies flew away. How many butterflies are left?
Answer: 8 - 5 = 3 butterflies left.
7 Hidden Dots & Hopping Backwards (Pages 62-63)
Page 62: Total Dots 10 (Hidden vs Visible)
If there are 10 dots total, figure out how many are hidden based on how many are visible.
| Total Dots | Hidden Dots (Under Hand) | Visible Dots |
|---|---|---|
| 10 | 0 | 10 |
| 10 | 3 | 7 |
| 10 | 5 | 5 |
| 10 | 6 | 4 |
Page 63: Hop backwards on the number strip (Subtraction).
A. Jump 3 steps back from 9. ➔ 9 - 3 = 6
B. Jump 4 steps back from 7. ➔ 7 - 4 = 3
Page 63: Do the subtraction in your own way.
