Step-by-step solution for: Printable Logic Puzzles for Kids | Woo! Jr. Kids Activities ...
Let's solve this logic puzzle step by step using the clues provided.
---
We need to determine:
- Which grade each child is in
- What their favorite color is
We'll use a grid and process the clues one by one.
---
- So, the 4th grader is a boy → must be Bill (only boy listed).
- The 4th grader does not like pink, so his favorite color is not pink.
- Therefore:
→ Bill is in 4th grade
→ Bill ≠ pink
---
- "Youngest" means 1st grade
- So: Dorothy is in 1st grade
- And: Dorothy’s favorite color is blue
So far:
- Dorothy → 1st grade, blue
- Bill → 4th grade, not pink
---
That means:
- Cathy's grade = Amanda's grade + 1
- So possible pairs:
- If Amanda is 1st → Cathy is 2nd
- If Amanda is 2nd → Cathy is 3rd
- If Amanda is 3rd → Cathy is 4th
- Cannot be 4th (no higher grade)
But we already know:
- Dorothy is in 1st
- Bill is in 4th
So grades:
- 1st: Dorothy
- 4th: Bill
Therefore, Amanda and Cathy must be in 2nd and 3rd.
From clue 3: Cathy is one grade ahead of Amanda → so:
- Amanda = 2nd → Cathy = 3rd
Because if Amanda were 3rd, Cathy would be 4th — but 4th is Bill.
So:
- Amanda → 2nd grade
- Cathy → 3rd grade
Now we have all grades assigned:
| Child | Grade |
|----------|-------|
| Dorothy | 1st |
| Amanda | 2nd |
| Cathy | 3rd |
| Bill | 4th |
---
- 2nd grader is Amanda
- So Amanda likes red
So now:
- Amanda → 2nd, red
---
Now let’s summarize what we have:
| Child | Grade | Color |
|----------|-------|--------|
| Dorothy | 1st | blue |
| Amanda | 2nd | red |
| Cathy | 3rd | ? |
| Bill | 4th | ? (not pink) |
Available colors: pink, green (blue and red taken)
- Dorothy → blue
- Amanda → red
- So remaining colors: pink, green
Available for Cathy and Bill.
But Bill ≠ pink (from clue 1), so Bill must like green
Then Cathy must like pink
---
Final assignments:
| Child | Grade | Color |
|----------|-------|--------|
| Dorothy | 1st | blue |
| Amanda | 2nd | red |
| Cathy | 3rd | pink |
| Bill | 4th | green |
---

Children: Amanda, Bill, Cathy, Dorothy
Grades: 1st, 2nd, 3rd, 4th
Colors: Blue, Red, Pink, Green
We need to determine:
- Which grade each child is in
- What their favorite color is
We'll use a grid and process the clues one by one.
---
Clue 1: *The 4th grader is a boy who does not like pink.*
- So, the 4th grader is a boy → must be Bill (only boy listed).
- The 4th grader does not like pink, so his favorite color is not pink.
- Therefore:
→ Bill is in 4th grade
→ Bill ≠ pink
---
Clue 2: *Dorothy is the youngest and likes blue.*
- "Youngest" means 1st grade
- So: Dorothy is in 1st grade
- And: Dorothy’s favorite color is blue
So far:
- Dorothy → 1st grade, blue
- Bill → 4th grade, not pink
---
Clue 3: *Cathy is one grade ahead of Amanda.*
That means:
- Cathy's grade = Amanda's grade + 1
- So possible pairs:
- If Amanda is 1st → Cathy is 2nd
- If Amanda is 2nd → Cathy is 3rd
- If Amanda is 3rd → Cathy is 4th
- Cannot be 4th (no higher grade)
But we already know:
- Dorothy is in 1st
- Bill is in 4th
So grades:
- 1st: Dorothy
- 4th: Bill
Therefore, Amanda and Cathy must be in 2nd and 3rd.
From clue 3: Cathy is one grade ahead of Amanda → so:
- Amanda = 2nd → Cathy = 3rd
Because if Amanda were 3rd, Cathy would be 4th — but 4th is Bill.
So:
- Amanda → 2nd grade
- Cathy → 3rd grade
Now we have all grades assigned:
| Child | Grade |
|----------|-------|
| Dorothy | 1st |
| Amanda | 2nd |
| Cathy | 3rd |
| Bill | 4th |
---
Clue 4: *The 2nd grader likes red.*
- 2nd grader is Amanda
- So Amanda likes red
So now:
- Amanda → 2nd, red
---
Now let’s summarize what we have:
| Child | Grade | Color |
|----------|-------|--------|
| Dorothy | 1st | blue |
| Amanda | 2nd | red |
| Cathy | 3rd | ? |
| Bill | 4th | ? (not pink) |
Available colors: pink, green (blue and red taken)
- Dorothy → blue
- Amanda → red
- So remaining colors: pink, green
Available for Cathy and Bill.
But Bill ≠ pink (from clue 1), so Bill must like green
Then Cathy must like pink

Final assignments:
| Child | Grade | Color |
|----------|-------|--------|
| Dorothy | 1st | blue |
| Amanda | 2nd | red |
| Cathy | 3rd | pink |
| Bill | 4th | green |
---
Let’s verify all clues:
1. The 4th grader is a boy who does not like pink.
→ Bill is a boy, 4th grade, likes green → ✔
2. Dorothy is the youngest and likes blue.
→ 1st grade = youngest, likes blue → ✔
3. Cathy is one grade ahead of Amanda.
→ Amanda = 2nd, Cathy = 3rd → ✔
4. The 2nd grader likes red.
→ Amanda is 2nd, likes red → ✔
All clues satisfied!
