Math practice worksheet for elementary students covering number patterns, basic arithmetic, ten frames, and time-telling.

Let's solve the problems step by step.

---

Part 1: Fill in the missing numbers

#### Sequence 1: \(2, 4, \_, 8, 10, \_, \_, 16, \_, \_, 22, \_\)
- This sequence increases by 2 each time.
- The missing numbers are:
- After 4: \(4 + 2 = 6\)
- After 8: \(10 + 2 = 12\)
- After 10: \(12 + 2 = 14\)
- After 16: \(16 + 2 = 18\)
- After 18: \(20 + 2 = 20\)
- After 22: \(22 + 2 = 24\)

So, the complete sequence is:
\(2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24\)

#### Sequence 2: \(5, 10, \_, 20, \_, \_, 35, 40, \_, \_\)
- This sequence increases by 5 each time.
- The missing numbers are:
- After 10: \(10 + 5 = 15\)
- After 20: \(20 + 5 = 25\)
- After 25: \(25 + 5 = 30\)
- After 40: \(40 + 5 = 45\)
- After 45: \(45 + 5 = 50\)

So, the complete sequence is:
\(5, 10, 15, 20, 25, 30, 35, 40, 45, 50\)

Part 2: Solve the addition and subtraction problems

1. \(15 + 4 = 19\)
2. \(20 - 8 = 12\)
3. \(11 + 5 = 16\)
4. \(14 - 8 = 6\)
5. \(16 - 4 = 12\)
6. \(10 + 5 = 15\)
7. \(9 + 9 = 18\)
8. \(12 + 6 = 18\)
9. \(12 - 5 = 7\)

---

Part 3: Fill in the ten frames to make 10. Complete the addition sentence

#### Frame 1:
- There are 6 filled circles.
- To make 10, we need \(10 - 6 = 4\) more circles.
- The addition sentence is: \(6 + 4 = 10\)

#### Frame 2:
- There are 2 filled circles.
- To make 10, we need \(10 - 2 = 8\) more circles.
- The addition sentence is: \(2 + 8 = 10\)

#### Frame 3:
- There are 4 filled circles.
- To make 10, we need \(10 - 4 = 6\) more circles.
- The addition sentence is: \(4 + 6 = 10\)

#### Frame 4:
- There are 5 filled circles.
- To make 10, we need \(10 - 5 = 5\) more circles.
- The addition sentence is: \(5 + 5 = 10\)

---

Part 4: Write the time below each clock

#### Clock 1:
- The hour hand is between 1 and 2, closer to 1.
- The minute hand is on 10, which represents 10 minutes past the hour.
- The time is: 1:10

#### Clock 2:
- The hour hand is on 7.
- The minute hand is on 12, which represents 0 minutes past the hour.
- The time is: 7:00

#### Clock 3:
- The hour hand is between 1 and 2, closer to 1.
- The minute hand is on 3, which represents 15 minutes past the hour.
- The time is: 1:15

5. Clock Times:
- Clock 1: 1:10
- Clock 2: 7:00
- Clock 3: 1:15
