Problem Description:
The task is to identify which items from the given list are "stretchy." Stretchy materials can be stretched or elongated without breaking. The goal is to circle the correct items that exhibit this property.
Solution Approach:
1.
Understand the Property of Stretchiness:
- Stretchy materials can be pulled and elongated, often returning to their original shape when released.
- Examples include rubber bands, elastic ropes, and certain fabrics.
2.
Analyze Each Item:
- Carefully examine each object in the image and determine if it can be stretched.
3.
Circle the Correct Items:
- Mark the items that are stretchy.

Analysis of Each Item:
#### Row 1:
-
Hammer: Not stretchy. It is a rigid tool made of metal and wood.
-
Elastic Rope (Jump Rope): Stretchy. Elastic ropes are designed to stretch and return to their original shape.
-
Mobile Phone: Not stretchy. It is a solid electronic device with no stretchable components.
#### Row 2:
-
Rubber Band: Stretchy. Rubber bands are specifically designed to stretch and return to their original shape.
-
Sunglasses: Not stretchy. Sunglasses are made of rigid materials like plastic and metal.
-
Iron: Not stretchy. An iron is a solid appliance used for smoothing clothes.
#### Row 3:
-
Toothpaste Tube: Not stretchy. Toothpaste tubes are flexible but not stretchy in the sense of being able to elongate significantly.
-
Mirror: Not stretchy. A mirror is a rigid object made of glass and metal.
-
Coiled Spring: Stretchy. Springs can be compressed or stretched and return to their original shape.
#### Row 4:
-
Lamp: Not stretchy. Lamps are rigid objects made of metal and other non-stretchable materials.
-
Trampoline: Stretchy. Trampolines have a fabric surface that stretches under pressure.
-
Drill: Not stretchy. Drills are solid tools with no stretchable parts.

Final Answer:
The stretchy items are:
1. Elastic Rope (Jump Rope)
2. Rubber Band
3. Coiled Spring
4. Trampoline
Circled Items:
-
Row 1, Column 2: Elastic Rope
-
Row 2, Column 1: Rubber Band
-
Row 3, Column 3: Coiled Spring
-
Row 4, Column 2: Trampoline
Boxed Final Answer:
\[
\boxed{\text{Elastic Rope, Rubber Band, Coiled Spring, Trampoline}}
\]
