Interactive worksheet teaching the prefix "sub-" with examples and illustrations.

You’ve uploaded an educational worksheet designed to teach students about the prefix “sub-”, which means “under”.

The task is to understand and apply the meaning of the prefix “sub-” by completing sentences and illustrations for words that begin with it. The worksheet already has some examples filled in — your job (or the student’s) is to complete the missing illustration for “submerge” based on the given sentence.

✔ Step-by-step Solution:

#### 1. Understand the Prefix
- Prefix: sub-
- Meaning: under

This means any word starting with “sub-” relates to being *under* something — physically, figuratively, or in hierarchy.

---

#### 2. Analyze the Given Examples

| Word | Sentence | Illustration (Already Drawn) |
|-------------|--------------------------------------------------------------------------|----------------------------------------|
| Submarine | “The submarine transports the crew under the water.” | A yellow submarine underwater |
| Subway | “We used the subway to get to the museum.” | A train underground |
| Subheading | “A subheading lets us know what the section will be about.” | A book page with “CONTINENTS” heading |
| Submerge| “The baby likes to submerge the rubber duck.” | Missing — needs to be drawn |

---

#### 3. Focus on the Missing Part: “Submerge”

- Sentence: “The baby likes to submerge the rubber duck.”
- Meaning: To put something *under* water.
- So, the illustration should show a rubber duck being pushed or sinking under water.

✔ What to draw:
> A yellow rubber duck partially or fully underwater in a tub or basin, with ripples or bubbles around it to show it’s submerged. You could even add a child’s hand pushing it down if you want to include the “baby.”

*(Note: The image you uploaded already shows a duck floating — but the sentence says “submerge,” so the duck should be UNDER the water, not floating on top.)*

---

🎯 Final Answer / Task Completion:

> Illustration for “submerge”:
> Draw a rubber duck underwater in a bathtub or pool, possibly with bubbles or a child’s hand pushing it down. This visually represents the meaning of “sub- = under.”

💡 Teaching Tip:

This activity reinforces vocabulary through:
- Context clues (sentences),
- Visual representation (illustrations),
- Root/prefix understanding (“sub-” = under).

It’s a great way to help students decode unfamiliar words using prefixes!
