Educational math worksheets for elementary students covering counting, addition, money, time, and number patterns.

Problem Analysis:

The image contains multiple sections with different tasks. Let's break them down and solve each one step by step.

---

#### Section 1: Count by twos
The task is to fill in the missing numbers in the sequence:
2, 4, __, 8, __, 10, __, 14, __, 16, __, 18.

Solution:
- The sequence is counting by twos.
- Starting from 2, we add 2 to each number to get the next one.
- Filling in the blanks:
- After 4: \( 4 + 2 = 6 \)
- After 8: \( 8 + 2 = 10 \) (already given)
- After 10: \( 10 + 2 = 12 \)
- After 14: \( 14 + 2 = 16 \) (already given)
- After 16: \( 16 + 2 = 18 \) (already given)

So, the completed sequence is:
2, 4, 6, 8, 10, 12, 14, 16, 18.

#### Section 2: Addition Problem
The problem states: "All the time Jill won three ribbons and then three more. How many ribbons did she win in all?"

Solution:
- Jill won 3 ribbons initially.
- She won 3 more ribbons later.
- Total ribbons = \( 3 + 3 = 6 \).

So, Jill won 6 ribbons in total.

#### Section 3: Circle the Answer
The task is to circle the correct answer for the addition problem:
\( 1 + 3 = \_\_\_ \).

Solution:
- Perform the addition: \( 1 + 3 = 4 \).
- Circle the number 4.

---

#### Section 4: Clock Reading
The task is to determine what the short hand shows on the clock.

Solution:
- The short hand (hour hand) is pointing at 1.
- Therefore, the short hand shows 1 hour.

---

#### Section 5: Multiplication Table
The task involves filling in a multiplication table for the numbers 2, 5, and 10.

Solution:
We need to fill in the missing values in the table. Here’s the completed table:

| | 2 | 5 | 10 |
|---|---|---|----|
| 2 | 4 | 10 | 20 |
| 5 | 10 | 25 | 50 |
| 10 | 20 | 50 | 100 |

---

#### Section 6: Basic Addition
The task involves solving simple addition problems.

Problems and Solutions:
1. \( 1 + 3 = 4 \)
2. \( 1 + 2 = 3 \)
3. \( 1 + 8 = 9 \)
4. \( 1 + 6 = 7 \)
5. \( 1 + 9 = 10 \)
6. \( 1 + 7 = 8 \)
7. \( 1 + 1 = 2 \)
8. \( 1 + 5 = 6 \)
9. \( 1 + 4 = 5 \)
10. \( 1 + 0 = 1 \)
