This prefixes worksheet helps students practice adding un-, re-, and dis- to complete sentences correctly.

Let’s go step by step.

We are given three prefixes and their meanings:
- un = means the opposite
- re = means to do again
- dis = means not or opposite

Now, let’s look at each sentence and pick the best prefix that makes sense.

---

1. Mother will ______ wrap the gift.
→ If she wrapped it before and is doing it again, we use “re”.
→ “Rewrap” = wrap again. Makes sense if maybe the first wrapping was messy.
✔ re

2. My dad had to ______ connect the light.
→ Maybe it wasn’t connected right the first time? So he has to do it again.
→ “Reconnect” = connect again.
✔ re

3. John had to ______ plant the seeds.
→ Maybe the first planting didn’t work? He needs to plant them again.
→ “Replant” = plant again.
✔ re

4. The teacher told Ann to ______ fold the paper.
→ Probably Ann folded it wrong, so she must fold it again.
→ “Refold” = fold again.
✔ re

5. The man ______ loaded the truck.
→ This one is tricky. Could be “reloaded” (loaded again) or “unloaded” (took things out). But the word after the blank is “loaded”, so adding “un” would make “unloaded” — which means took stuff OUT of the truck. That also makes sense.
Let’s think: if he “unloaded” the truck, that’s a common phrase. “Reloaded” could mean put more in, but without context, both might fit. However, looking at the pattern — most sentences here are about redoing something. But wait — #6 says “He ___ did his shoes.” That’s likely “undid” (untied/unfastened). So maybe #5 is “unloaded”? Actually, let’s check all together.

Wait — let’s hold on #5 for now and come back.

6. He ______ did his shoes.
→ “Did his shoes” probably means tied or fastened them. So “undid” = untied/unfastened.
→ “Undid” uses “un” = opposite of did (in this context, opposite of tying/fastening).
✔ un

7. Kim ______ likes eating fruit.
→ “Likes” → opposite is “doesn’t like”. So “dislikes” = does not like.
✔ dis

8. The bottle is hard to ______ open.
→ “Open” → opposite is “close”, but we’re talking about opening. Wait — “hard to ___ open” — if it’s hard to open, maybe you need to “reopen” it? No, that doesn’t fit. Actually, “hard to open” already means difficult to open. Adding “un” would make “unopen” — which isn’t really a word. “Disopen”? Not real. “Reopen”? That means open again — which could make sense if it was closed and you’re trying to open it again. But the sentence says “hard to ___ open” — implying difficulty in the action of opening. Hmm.

Actually, let’s rethink: maybe it’s “hard to unopen”? But “unopen” isn’t standard. Perhaps it’s “hard to reopen”? Like, it’s stuck shut and hard to open again? That could work.

But wait — another idea: maybe it’s “hard to disclose”? No, the word is “open”.

Hold on — perhaps I misread. The sentence is: “The bottle is hard to ______ open.”

If we add “un”, we get “unopen” — not correct.

Add “re” → “reopen” — possible, if it was opened before and now hard to open again.

Add “dis” → “disopen” — not a word.

So only “re” makes a real word: “reopen”.

But is that the intended meaning? Maybe the bottle is sealed tight and hard to open — no prior opening mentioned.

Alternatively — maybe it’s a trick? Or perhaps I made a mistake earlier.

Wait — let’s look at #9:

9. The rope is hard to ______ tie.
→ Similar structure. “Hard to ___ tie”.

If we add “un” → “untie” — which means to undo a knot. But the sentence says “hard to ___ tie” — if it’s hard to untie, that makes sense. But the verb is “tie”, not “untie”.

Ah! Here’s the key: the base word is “tie”, and we’re adding a prefix to change its meaning.

So for #9: “The rope is hard to ______ tie.”

If we say “untie”, that’s the opposite of tie — so “hard to untie” = hard to undo the knot. That makes perfect sense.

Similarly, for #8: “The bottle is hard to ______ open.”

If we say “unopen” — not a word. But “reopen” is a word — but does it fit?

Wait — what if #8 is actually meant to be “hard to close”? But the word given is “open”.

Perhaps there’s a typo in my thinking.

Another approach: let’s list all the words we can form:

From the root words:

1. wrap → rewrap, unwrap, diswrap? (diswrap not common)
2. connect → reconnect, disconnect, unconnect? (disconnect is common)
3. plant → replant, uproot? (not from these prefixes), displant? no
4. fold → refold, unfold, disfolding? no
5. load → reload, unload, disload? (unload is common)
6. do → undo, redo, disdo? (undo and redo are common)
7. like → dislike, unlike? (dislike is common for verbs; unlike is adjective)
8. open → reopen, unopen? (no), disopen? no → only reopen works as a verb
9. tie → untie, retie, distie? (untie and retie are common)

Now, let’s match with context:

1. Mother will ___ wrap the gift. → If she’s wrapping it again, “rewrap”. If she’s taking off old wrap, “unwrap”. But the sentence doesn’t specify. However, typically, when we say “will ___ wrap”, and no prior mention, “rewrap” implies doing it again, which is plausible. But “unwrap” would mean removing wrap — which might not make sense if she’s preparing a gift. Usually, you wrap a gift, not unwrap it unless returning. So likely “rewrap” if it was poorly wrapped, or just “wrap” — but we have to choose a prefix. Since “wrap” alone isn’t an option, and “rewrap” is logical, I’ll stick with “re”.

But wait — let’s see the answer choices per sentence. We must pick one prefix per sentence.

Looking at #6: “He ___ did his shoes.” → “undid” is clear — he untied/unfastened them.

#7: “Kim ___ likes eating fruit.” → “dislikes” — doesn’t like.

#9: “The rope is hard to ___ tie.” → If it’s hard to untie, then “untie” — so prefix “un”.

That suggests “un” is used for opposites.

For #8: “The bottle is hard to ___ open.” — if we follow the same logic, “unopen” isn’t a word, but “reopen” is. However, “hard to reopen” implies it was open before and now hard to open again — possible.

But let’s consider: maybe #8 is “hard to close”? But the word is “open”.

Another thought: perhaps “dis” can be used with “open”? “Disopen” — no.

I recall that “unlock” is a word, but not from these prefixes.

Perhaps for #8, it’s “reopen” — let’s assume that.

But let’s look at #5: “The man ___ loaded the truck.”

If he “unloaded” the truck, that means he took things out — very common phrase.

If he “reloaded”, he put more in.

Without context, both are possible, but “unloaded” is more commonly used in such sentences.

Also, in many worksheets, they use “unload” for taking cargo out.

Moreover, if we use “un” for #5, then we have:

#5: unloaded

#6: undid

#9: untie

That’s three “un”s — which is fine.

#7: dislikes — “dis”

#1-4: likely “re” for redoing actions.

#8: ?

For #8, if we try “unopen” — invalid.

“Disopen” — invalid.

“Reopen” — valid, and makes sense if the bottle was opened before and now hard to open again.

Perhaps that’s it.

Let me assign:

1. rewrap

2. reconnect

3. replant

4. refold

5. unloaded → un

6. undid → un

7. dislikes → dis

8. reopen → re

9. untie → un

But #8: “The bottle is hard to reopen.” — yes, that works.

Is there any other possibility? What if #8 is “hard to close”? But the word is “open”, so we can’t change the root word.

Another idea: perhaps “dis” can be used as “disable”, but not with “open”.

I think “reopen” is the only grammatical choice.

But let’s double-check #5.

“The man ___ loaded the truck.”

If we say “reloaded”, it means he loaded it again — perhaps after unloading.

But “unloaded” is more straightforward — he removed the load.

In educational contexts, “unload” is often taught as the opposite of “load”.

Similarly, “undo” for #6.

“Untie” for #9.

So for consistency, let’s use:

1. re

2. re

3. re

4. re

5. un (unloaded)

6. un (undid)

7. dis (dislikes)

8. re (reopen) — because "unopen" isn't a word

9. un (untie)

But #8: “The bottle is hard to reopen.” — is that natural? It could be, if it’s a bottle that was opened and now the cap is stuck.

Whereas “hard to open” without prefix would be normal, but we have to add a prefix.

Perhaps the intended answer for #8 is “un”, even though “unopen” isn't standard? But that seems unlikely.

Wait — I recall that “unbutton”, “untie”, “unlock” are common, but “unopen” is not used. Instead, we say “cannot open” or “hard to open”.

But in this exercise, we must use one of the prefixes.

Another thought: for #8, if we use “dis”, “disopen” — no.

Perhaps it’s a mistake, and it should be “close”, but it’s written as “open”.

Let’s look online or recall standard answers.

Since I can’t, let’s think logically.

For #9: “The rope is hard to ___ tie.” — if it’s hard to untie, then “untie” — so “un”.

Similarly, for #8, if it’s hard to close, but the word is “open”, so perhaps it’s “hard to keep open” or something.

I found a better way: let's consider the meaning.

"The bottle is hard to ______ open."

If we add "re", "reopen" means to open again — which implies it was open before, closed, and now hard to open again. Possible.

If we add "un", "unopen" — not a word.

If we add "dis", "disopen" — not a word.

So only "re" creates a valid English word.

Therefore, #8 must be "re".

Similarly, for #5, "unloaded" is valid and common.

So final assignment:

1. re

2. re

3. re

4. re

5. un

6. un

7. dis

8. re

9. un

Now, let's write the answers:

1. rewrap

2. reconnect

3. replant

4. refold

5. unloaded

6. undid

7. dislikes

8. reopen

9. untie

Yes, all are valid words and make sense in context.

For #8, "The bottle is hard to reopen." — acceptable.

Some might argue for #5 being "reloaded", but "unloaded" is more commonly associated with trucks in such contexts.

Also, in the list, we have three "re", three "un", and one "dis" — balanced.

#7 is clearly "dislikes".

So I think this is correct.

Final Answer:

1. re
2. re
3. re
4. re
5. un
6. un
7. dis
8. re
9. un
