Math practice worksheet for elementary students covering number sequences, addition, and basic arithmetic.

Let's solve each part of the worksheet step by step and explain the solutions clearly.

A) Write before, after or between the numbers.

We need to fill in the missing numbers based on their position relative to the given numbers.

| 134 ....... | ....... 168 | ....... 200 | ....... 198 |
|------------|------------|------------|------------|
| ....... 170 | 189 ...... 191 | 147 ...... 149 | ....... 167 |
| 155 ...... 157 | ....... 100 | 121 ........ | 123 ........ |

Explanation:
- "Before" means the number that comes just before.
- "After" means the number that comes just after.
- "Between" means the number(s) in the middle.

Now fill in:

1. 134 ....... → The number after 134 is 135
2. ....... 168 → The number before 168 is 167
3. ....... 200 → The number before 200 is 199
4. ....... 198 → The number before 198 is 197
5. ....... 170 → The number before 170 is 169
6. 189 ...... 191 → Number between 189 and 191 is 190
7. 147 ...... 149 → Number between 147 and 149 is 148
8. ....... 167 → The number before 167 is 166
9. 155 ...... 157 → Number between 155 and 157 is 156
10. ....... 100 → The number before 100 is 99
11. 121 ........ → The number after 121 is 122
12. 123 ........ → The number after 123 is 124

✔ Final answers:
```
134 135 167 168 199 200 197 198
169 170 189 190 191 147 148 149 166 167
155 156 157 99 100 121 122 123 124
```

B) Write in decreasing/descending order.

#### i) 136, 106, 183, 193
Arrange from largest to smallest:
193 > 183 > 136 > 106
→ 193, 183, 136, 106

#### ii) 192, 122, 185, 135
192 > 185 > 135 > 122
→ 192, 185, 135, 122

✔ Answers:
- i) 193, 183, 136, 106
- ii) 192, 185, 135, 122

C) Write in increasing/ascending order.

#### i) 156, 146, 172, 122
Smallest to largest:
122 < 146 < 156 < 172
→ 122, 146, 156, 172

#### ii) 132, 102, 154, 144
102 < 132 < 144 < 154
→ 102, 132, 144, 154

✔ Answers:
- i) 122, 146, 156, 172
- ii) 102, 132, 144, 154

D) Write in short form.

This means convert expanded form to standard number.

i) 1 hundred + 3 tens + 2 ones = 100 + 30 + 2 = 132
ii) 1 hundred + 0 tens + 6 ones = 100 + 0 + 6 = 106
iii) 1 hundred + 5 tens + 4 ones = 100 + 50 + 4 = 154
iv) 1 hundred + 6 tens + 3 ones = 100 + 60 + 3 = 163

✔ Answers:
- i) 132
- ii) 106
- iii) 154
- iv) 163

---

E) Write the number.

i) 100 + 70 + 6 = 176
ii) 100 + 50 + 3 = 153
iii) 100 + 20 + 9 = 129

✔ Answers:
- i) 176
- ii) 153
- iii) 129

F) Mental math.

#### i)
- 2 less than 15 = 15 - 2 = 13
- 1 less than 18 = 18 - 1 = 17
- 2 less than 12 = 12 - 2 = 10

#### ii)
- 2 more than 8 = 8 + 2 = 10
- 3 more than 14 = 14 + 3 = 17
- 1 more than 5 = 5 + 1 = 6

#### iii) Largest 1-digit number = 9

#### iv) Smallest 1-digit number = 1

#### v) Circle the greatest: 98, 46, 38, 19, 83, 78
Compare: 98 is the largest → 98

#### vi) Circle the smallest: 35, 56, 79, 64, 23, 10
Smallest is 10

#### vii) Smallest 2-digit number = 10

#### viii) Place of 5 in 165?
165 → 1 (hundreds), 6 (tens), 5 (ones) → Ones place
In 156 → 1 (hundreds), 5 (tens), 6 (ones) → Tens place

So:
- In 165 → Ones
- In 156 → Tens

#### ix) Write in expanded form: 234
= 200 + 30 + 4

✔ Answers:
- i) 13, 17, 10
- ii) 10, 17, 6
- iii) 9
- iv) 1
- v) 98
- vi) 10
- vii) 10
- viii) Ones, Tens
- ix) 200 + 30 + 4
