Educational counting chart featuring numbers 16 to 20 with visual representations using stars, circles, and dots.

It looks like you've uploaded a worksheet from Dar Al Manhal Publishers with a series of pattern recognition tasks. The task is labeled "أعد وأصل" which means "Count and Complete" in Arabic.

Let's analyze each problem step by step:

---

🔹 Problem 16: Stars (Red)

- Given: 5 red stars in the first row, 4 in the second, 3 in the third.
- Pattern: Decreasing by 1 each time → 5, 4, 3
- So next should be 2, then 1.
- But only one more row is shown — it has 1 star already.
- ✔ This pattern is complete: 5 → 4 → 3 → 2 → 1

> ✔️ Answer for 16: Already completed correctly.

🔹 Problem 17: Circles (Blue)

- First row: 5 blue circles
- Second row: 4 blue circles
- Third row: 3 blue circles
- Pattern: Decreasing by 1 → 5, 4, 3
- Next should be 2, then 1
- But only one more row is shown — it has 1 circle
- ✔ Again, this seems to follow the same decreasing pattern: 5 → 4 → 3 → 2 → 1

Wait — but the third row shows 3 circles, and the fourth row has only 1 circle?

That doesn’t match.

Let’s count carefully:
- Row 1: 5 circles
- Row 2: 4 circles
- Row 3: 3 circles
- Row 4: 1 circle ← Missing 2

So there’s an error here.

But perhaps the task is to fill in the missing one? Let’s check the layout.

Actually, looking closely at the image:
- Row 1: 5 circles
- Row 2: 4 circles
- Row 3: 3 circles
- Row 4: ??? — currently has 1 circle, but should have 2

Wait — maybe the last row is incomplete, and we need to add one more circle to make it 2?

Yes! That makes sense.

> ✘ Current: 5, 4, 3, 1 → incorrect
> ✔ Should be: 5, 4, 3, 2, 1

So add one more blue circle to the last row.

> ✔ Answer for 17: Add 1 more blue circle to make 2 in the last row.

🔹 Problem 18: Triangles (Pink)

- Row 1: 5 triangles
- Row 2: 4 triangles
- Row 3: 3 triangles
- Row 4: 1 triangle

Same issue as above.

Pattern: 5, 4, 3 → next should be 2, not 1.

So again, the last row is missing one triangle.

> ✔ Answer for 18: Add 1 more pink triangle to make 2 in the last row.

🔹 Problem 19: Circles (Green)

- Row 1: 5 green circles
- Row 2: 4 green circles
- Row 3: 3 green circles
- Row 4: 1 green circle

Again, same pattern: 5 → 4 → 3 → ? → ?

Should be 2 → 1

So last row has 1, but missing 2nd → so needs one more.

> ✔ Answer for 19: Add 1 more green circle to make 2 in the last row.

🔹 Problem 20: Stars (Yellow)

- Row 1: 5 yellow stars
- Row 2: 4 yellow stars
- Row 3: 3 yellow stars
- Row 4: 1 yellow star

Again, same pattern: 5, 4, 3 → should be 2 → 1

But only 1 star shown in the last row.

So need to add one more yellow star to make it 2.

> ✔ Answer for 20: Add 1 more yellow star to make 2 in the last row.

## ✔ Final Answers Summary:

| Number | Task | What to Do |
|-------|------|------------|
| 16 | Red Stars | Already correct (5→4→3→2→1) |
| 17 | Blue Circles | Add 1 blue circle to last row (make it 2) |
| 18 | Pink Triangles | Add 1 pink triangle to last row (make it 2) |
| 19 | Green Circles | Add 1 green circle to last row (make it 2) |
| 20 | Yellow Stars | Add 1 yellow star to last row (make it 2) |

🧠 Explanation:

This is a pattern recognition exercise where the number of shapes decreases by one in each row:
- 5 → 4 → 3 → 2 → 1
- The student must complete the pattern by adding the missing shape(s).

In all cases except #16, the last row has only 1 shape, but should have 2.

Thus, the task is to add one more shape to each of the last rows in problems 17–20.

---

✔ Final Answer:
Add one more shape to the last row of problems 17, 18, 19, and 20 to complete the descending pattern from 5 down to 1.
