Critical thinking worksheet where students use clues to determine the ages of four children, Emily, Anthony, Sarah, and Winston, ranging from 8 to 11 years old.

To solve the problem, we need to use the clues provided and deduce the ages of Emily, Anthony, Sarah, and Winston. Let's break it down step by step.

Clues Recap:

1. Sarah’s age is an odd number.
2. Emily is younger than Sarah.
3. Anthony is the oldest child.

Step-by-Step Solution:

#### Step 1: Identify possible ages for each person
The ages range from 8 to 11 years old. The odd numbers in this range are 9 and 11. The even numbers are 8 and 10.

#### Step 2: Use Clue 1 (Sarah’s age is an odd number)
- Sarah’s age must be either 9 or 11.

#### Step 3: Use Clue 3 (Anthony is the oldest child)
- Since Anthony is the oldest, his age must be 11.
- Therefore, Sarah cannot be 11 (since she is not the oldest). So, Sarah’s age must be 9.

#### Step 4: Use Clue 2 (Emily is younger than Sarah)
- Sarah’s age is 9.
- Emily must be younger than 9, so her age can only be 8.

#### Step 5: Determine Winston’s age
- The remaining age is 10.
- Since Winston is the only one left, his age must be 10.

Final Assignments:

- Emily: 8 years old
- Anthony: 11 years old
- Sarah: 9 years old
- Winston: 10 years old

Verification:

1. Sarah’s age is 9, which is an odd number. (Clue 1 satisfied)
2. Emily is 8, which is younger than Sarah (9). (Clue 2 satisfied)
3. Anthony is 11, which is the oldest. (Clue 3 satisfied)
