Prefixes worksheet for educational use, focusing on word formation with un-, re-, and dis-.

To solve this worksheet, we need to look at the meaning of each sentence and choose the prefix (un-, re-, or dis-) that makes the most sense.

Here is the key from the top of the page:
* un- means the opposite.
* re- means to do again.
* dis- means not or opposite.

Let's go through each question step-by-step:

1. Mother will \_\_\_\_\_\_ wrap the gift.
* If you wrap a gift, it is covered. If you take the paper off, you are doing the opposite of wrapping. The word for taking wrapping off is "unwrap."
* Prefix: un

2. My dad had to \_\_\_\_\_\_ connect the light.
* Usually, if something isn't working, you might try connecting it again. Or, if it was connected wrong, you disconnect it. However, "reconnect" is a very common action when fixing things (like wires). Let's look at the other options. "Unconnect" isn't really a standard word (we usually say disconnect). "Disconnect" fits well too. Let's hold on this one and check the others to see which prefixes are used most. Actually, looking at typical homework patterns, "reconnect" implies putting it back together after it fell apart. "Disconnect" implies taking it apart. Without more context, both *could* work, but let's look at #8. #8 says "The bottle is hard to \_\_\_\_\_ open." That is definitely "open" -> "reopen"? No, bottles are usually "opened". Wait, if a bottle is sealed, you open it. If it's hard to *open*, there is no prefix needed unless it was closed before? No, "hard to open" is standard. Ah, the blank is before "open". So it's "hard to [prefix]open". If it's a new bottle, you just open it. If it's a bottle that was closed, you reopen it? Let's re-read carefully.
* Let's look at standard usage.
* Sentence 2: "My dad had to reconnect the light" (maybe it came loose) OR "disconnect the light" (to fix it). Let's look for clues in other sentences.
* Sentence 4: "The teacher told Ann to \_\_\_\_\_ fold the paper." If you fold it once, and then do it again, it's refold. If you unfold it, it's unfold. Usually, teachers ask students to *unfold* paper to read it, or *refold* it neatly.
* Sentence 5: "The man \_\_\_\_\_ loaded the truck." This implies he did it again. Reloaded.
* Sentence 6: "He \_\_\_\_\_ did his shoes." This is likely a typo for "tied". "He \_\_\_\_\_ tied his shoes." If he did it again, it's retied. If he took them off, it's untied. Given the pattern, let's assume the verb is "tie". "Untied" makes sense for taking shoes off. "Retied" makes sense if they came loose.
* Sentence 7: "Kim \_\_\_\_\_ likes eating fruit." This expresses a negative feeling. She does *not* like it. So, dislikes.
* Sentence 8: "The bottle is hard to \_\_\_\_\_ open." If a bottle is already open, you don't open it again. But maybe it means "reopen"? Or is it "unopen"? No. Let's look at the root word. Is the root "close"? No, the text says "open". Is it possible the text meant "close"? "Hard to close"? No, it clearly says "open". Let's reconsider. Maybe the word is reopen? Like a bottle with a cap you put back on? Yes, reopen is a valid word.
* Sentence 9: "The rope is hard to \_\_\_\_\_ tie." If you tie a knot, and it's hard, maybe you have to retie it? Or untie it? Usually, ropes are hard to *untie*. So untie.

Let's refine the choices based on common 3rd/4th-grade vocabulary:

1. unwrap: Taking paper off a gift. (Correct)
2. reconnect or disconnect: Let's look at #4.
4. refold or unfold: Teachers often say "unfold your paper" to start a test. Or "refold your paper" when done.
5. reloaded: He filled the truck again. (Strong candidate for re-)
7. dislikes: Opposite of like. (Strong candidate for dis-)
9. untie: Opposite of tie. Ropes are notoriously hard to untie. (Strong candidate for un-)

Let's assign the strong ones first:
* #1: unwrap
* #5: reloaded
* #7: dislikes
* #9: untie (or retie? "Hard to retie" implies you failed the first time. "Hard to untie" is a very common phrase). Let's go with untie.

Now back to the tricky ones:
* #2: Dad had to \_\_\_\_ connect. If #9 is un-, and #1 is un-, we have plenty of uns. What about #6? "He \_\_\_\_ did his shoes." Assuming the word is "tied" (typo in my thought process? The image says "did his shoes"?? No, looking closely at crop 5, it says "He \_\_\_\_\_\_ did his shoes." Wait, "did" is not a word you prefix with un/re/dis easily. "Undid"? Yes! Undo. You undo your shoes. So #6 is undid.
* Correction: The verb is do. Past tense did. Prefix un- makes undo / undid. So #6 is un.

* Now let's look at #3: "John had to \_\_\_\_\_ plant the seeds."
* Did he plant them again? Replant.
* Did he not plant them? Displant? (Not a common word for kids).
* Did he unplant them? No.
* So #3 is likely replant.

* Now #4: "The teacher told Ann to \_\_\_\_\_ fold the paper."
* Unfold (open it up) or Refold (fold it again). Both are common. Let's see what prefixes are left. We have used un (#1, #6), re (#3, #5). We haven't used dis much yet, except #7.
* Let's check #8: "The bottle is hard to \_\_\_\_\_ open."
* Reopen? Unopen? (No). Disopen? (No).
* So #8 must be reopen.

* Let's check #2 again: "My dad had to \_\_\_\_\_ connect the light."
* Reconnect or Disconnect.
* If we use re for #8 and #5 and #3, that's a lot of 're's.
* If we use dis for #2 (disconnect), that balances it out. Disconnecting a light is a very standard safety step.

* Let's check #4 again: "The teacher told Ann to \_\_\_\_\_ fold the paper."
* If we use un for #1, #6, #9...
* Let's look at #9: "The rope is hard to \_\_\_\_\_ tie."
* Is it untie? Yes, knots are hard to untie.
* Is it retie? Maybe.
* But "hard to untie" is a classic idiom/phrase.

Let's try this distribution:
1. unwrap (Opposite of wrap)
2. reconnect (Connect again) OR disconnect. Let's look at #8.
3. replant (Plant again)
4. unfold (Open the paper) OR refold.
5. reloaded (Loaded again)
6. undid (Opposite of did/tied)
7. dislikes (Opposite of likes)
8. reopen (Open again) OR unopen? No.
9. untie (Opposite of tie)

Let's reconsider #2 and #4 and #8 to ensure variety and logic.
* #2: reconnect is good. disconnect is good.
* #4: unfold is very common in school ("Unfold your papers").
* #8: reopen.

Let's look at #2 vs #7. #7 is definitely dislikes. Are there other dis words?
* Disagree? No.
* Disappear? No.
* Disconnect? Yes.
* So #2 could be disconnect.

Let's look at #9. "The rope is hard to \_\_\_\_ tie."
* If I tie a shoe, and it comes loose, I retie it.
* If I want to take my shoes off, I untie them.
* "Hard to untie" is a very common complaint about knots. So untie.

Let's look at #6. "He \_\_\_\_ did his shoes."
* The verb is "do". He undid his shoes. (Meaning he untied them). This matches #9 being untie? It seems redundant to have two "shoe" related questions with the same prefix.
* Maybe #6 is redid? No, you don't "redo" shoes unless you messed up tying them.
* Maybe #9 is retie? "The rope is hard to retie." This implies you tried once and failed.
* Let's stick with the most common definitions.
* Undo/Undid = Reverse the action.
* Untie = Reverse the action.

Let's look at #8 again. "The bottle is hard to \_\_\_\_ open."
* Could it be unopen? No.
* Could it be disopen? No.
* It has to be reopen.

So far:
1. un
2. ?
3. re
4. ?
5. re
6. un
7. dis
8. re
9. un

We have:
un: 1, 6, 9
re: 3, 5, 8
dis: 7

Leftovers: #2 and #4.
#2: connect. reconnect or disconnect.
#4: fold. unfold or refold.

If we make #2 disconnect, we have two 'dis' words.
If we make #4 unfold, we have four 'un' words.

Let's check if #4 could be disfold? No.
Let's check if #2 could be unconnect? No, not a real word.

So #2 is either re or dis.
And #4 is either un or re.

Context clue for #4: "The teacher told Ann to..."
Usually, at the start of class: "Unfold your papers."
At the end of class: "Refold your papers."
Both are valid.

Context clue for #2: "My dad had to..."
"Had to reconnect" implies it broke.
"Had to disconnect" implies he was working on it.

Let's look at the balance.
If #4 is unfold, we have 4 uns.
If #2 is reconnect, we have 4 res.
If #2 is disconnect, we have 2 dises.

Let's look at #9 again. "The rope is hard to \_\_\_\_ tie."
Is it possible the word is retie?
If #9 is retie, then we have:
un: 1, 6
re: 3, 5, 8, 9
dis: 7
Left: #2, #4.
If #2 is disconnect and #4 is unfold:
un: 1, 4, 6
re: 3, 5, 8, 9
dis: 2, 7
This feels balanced.

However, "Hard to untie" is much more common than "Hard to retie". Knots get stuck. You don't usually struggle to tie them again unless you are learning. You struggle to get them apart. So #9 is almost certainly untie.

So back to:
un: 1, 6, 9
re: 3, 5, 8
dis: 7
Left: #2, #4.

If #2 is reconnect and #4 is unfold:
un: 1, 4, 6, 9 (4 words)
re: 2, 3, 5, 8 (4 words)
dis: 7 (1 word)
This leaves only one "dis" word. Is there another place for "dis"?
Can #4 be disfold? No.
Can #9 be distie? No.
Can #1 be diswrap? No.
Can #3 be displant? No.
Can #5 be disloaded? No (unloaded is the word, but prefix is un-).
Can #8 be disopen? No.

So "dis" might only appear once or twice.
What if #2 is disconnect?
Then:
un: 1, 4, 6, 9
re: 3, 5, 8
dis: 2, 7

What if #4 is refold?
Then:
un: 1, 6, 9
re: 3, 4, 5, 8
dis: 2, 7 (if #2 is dis) OR dis: 7 (if #2 is re)

Let's look at #2 again. "My dad had to \_\_\_\_ connect the light."
In many household contexts, you disconnect appliances before fixing them.
But you also reconnect them after fixing.
"Had to" suggests a necessity due to a problem. "The light was flickering, so dad had to disconnect it." Or "The wire fell out, so dad had to reconnect it." Both work.

Let's look at #4. "The teacher told Ann to \_\_\_\_ fold the paper."
If Ann just received a folded handout, she must unfold it.
If Ann finished her work, she might refold it.
"Unfold" is a very primary skill taught with prefixes.

Let's assume the most standard "opposite" and "again" meanings.
1. unwrap (opposite)
2. reconnect (again) - *Let's tentatively pick re-*
3. replant (again)
4. unfold (opposite)
5. reloaded (again)
6. undid (opposite)
7. dislikes (opposite/negative)
8. reopen (again)
9. untie (opposite)

This gives us:
Un: 1, 4, 6, 9
Re: 2, 3, 5, 8
Dis: 7

Is there any way to get another "dis"?
Maybe #9 is distie? No.
Maybe #1 is diswrap? No.
Maybe #2 is disconnect?
If #2 is disconnect, we have:
Un: 1, 4, 6, 9
Re: 3, 5, 8
Dis: 2, 7

This seems like a very reasonable distribution. "Disconnect" is a very common word. "Reconnect" is also common. But "Disconnect" pairs nicely with "Dislikes" as the "negative/opposite" prefix group.

Let's double check #6. "He \_\_\_\_ did his shoes."
The base word is "do".
Undo -> Undid.
Redo -> Redid.
Disdo -> Doesn't exist.
So it's either Undid or Redid.
"He redid his shoes" sounds weird. You redo a task. You don't redo shoes. You *retie* shoes. But the word is "did". So it must be undid (he took them off).

Let's double check #9. "The rope is hard to \_\_\_\_ tie."
Base word: Tie.
Untie -> Opposite.
Retie -> Again.
Distie -> Doesn't exist.
"Hard to untie" is a standard phrase. "Hard to retie" is less standard. So untie.

So #6 and #9 are both un-.

Let's double check #4. "Fold".
Unfold -> Opposite.
Refold -> Again.
Disfold -> Doesn't exist.
"Teacher told Ann to unfold the paper" is a very common classroom instruction.

So #1, #4, #6, #9 are un-.

Let's double check #3, #5, #8.
#3 Plant -> Replant (Again). Correct.
#5 Load -> Reloaded (Again). Correct.
#8 Open -> Reopen (Again). Correct.

So #3, #5, #8 are re-.

This leaves #2 and #7 for dis-?
#7 Likes -> Dislikes. Correct.
#2 Connect -> Disconnect? Or Reconnect?
If #2 is Reconnect, it joins the 're' group.
If #2 is Disconnect, it joins the 'dis' group.

Let's look at the visual spacing or any other clues. There are none.
However, "Disconnect" is a distinct concept from "Unconnect" (which isn't a word). Since we have established "Un-" for opposites where the word exists (unwrap, undo, untie, unfold), and "Dis-" for opposites where "Un-" doesn't fit or adds a negative meaning (dislike), does "Connect" take "Un-" or "Dis-"?
We say "Disconnect". We do NOT say "Unconnect".
Therefore, the opposite of connect is disconnect.
The prefix dis- means "not" or "opposite".
So #2 should be disconnect.

Final Check:
1. unwrap (Opposite of wrap)
2. disconnect (Opposite of connect; "unconnect" is incorrect)
3. replant (Do again)
4. unfold (Opposite of fold)
5. reloaded (Do again)
6. undid (Opposite of did/do)
7. dislikes (Negative/Opposite of like)
8. reopen (Do again)
9. untie (Opposite of tie)

This uses all three prefixes logically.
Un-: 1, 4, 6, 9
Re-: 3, 5, 8
Dis-: 2, 7

This feels correct.

Final Answer:
1. unwrap
2. disconnect
3. replant
4. unfold
5. reloaded
6. undid
7. dislikes
8. reopen
9. untie
