I'll work through this polygon naming worksheet step by step.

Step 1: Understanding the reference chart
The top of the page shows polygons named by their number of sides:
- Triangle = 3 sides
- Quadrilateral = 4 sides (can be different shapes)
- Pentagon = 5 sides
- Hexagon = 6 sides
- Octagon = 8 sides

Quadrilaterals shown include: rectangle, rhombus, square, parallelogram, trapezoid

Step 2: "Circle the quadrilaterals" section
Quadrilaterals have exactly 4 sides. Let me identify each shape:
- Shape 1 (top left): 8-sided figure → NOT a quadrilateral
- Shape 2 (top middle-left): 4-sided figure with opposite sides parallel → YES, quadrilateral
- Shape 3 (top middle-right): 4-sided figure → YES, quadrilateral
- Shape 4 (top right): 4-sided figure → YES, quadrilateral
- Shape 5 (bottom left): 6-sided figure → NOT a quadrilateral
- Shape 6 (bottom middle-left): oval/ellipse → NOT a quadrilateral (not even a polygon)
- Shape 7 (bottom middle-right): vertical line/rectangle → This appears to be a thin rectangle, which is 4-sided → YES, quadrilateral
- Shape 8 (bottom right): 3-sided figure → NOT a quadrilateral

So the quadrilaterals to circle are: the three 4-sided figures in the top row and the thin vertical rectangle.

Step 3: "Write the name of each polygon in the box" section
Let me identify each shape from left to right, top to bottom:

Top row:
1. Parallelogram (4 sides, opposite sides parallel)
2. Pentagon (5 sides)
3. Rectangle (4 sides, right angles)
4. Square (4 equal sides, right angles)

Bottom row:
5. Hexagon (6 sides)
6. Rhombus (4 equal sides)
7. Rectangle (4 sides, right angles)
8. Trapezoid (4 sides, one pair of parallel sides)
9. Triangle (3 sides)

Wait, let me recount the bottom row more carefully looking at the image layout...

Actually, I need to be more careful. Let me count again:

Looking at the bottom section, there appear to be 9 boxes total arranged in rows. Let me identify each:

Row 1 (4 shapes):
- Parallelogram
- Pentagon
- Rectangle
- Square

Row 2 (5 shapes):
- Hexagon
- Rhombus
- Rectangle
- Trapezoid
- Triangle

Final Answer:

Circle the quadrilaterals: Circle the 4-sided shapes (the parallelogram-like shape, the irregular quadrilateral, the diamond/rhombus shape, and the thin vertical rectangle). Do NOT circle the octagon, ellipse, or triangle.

Write the names:
1. Parallelogram
2. Pentagon
3. Rectangle
4. Square
5. Hexagon
6. Rhombus
7. Rectangle
8. Trapezoid
9. Triangle
