Third Grade Spelling worksheet featuring words with missing letters for students to complete.

Let's solve this Third Grade Spelling worksheet step by step.

Directions Recap:

- Look at each word.
- Determine if there are any missing letters.
- On the first line, write "yes" if letters are missing, or "no" if the word is correct as written.
- On the second line, write the correct spelling of the word, adding any missing letters.

Now, let’s go through each word:

9. los
- The correct word is lose.
- Missing letter: e
- Answer:
- First line: yes
- Second line: lose

10. lav
- The correct word is lave (less common) or possibly lava? But in third-grade context, likely meant to be lava or lawn? Let's analyze.

Wait — "lav" could be short for lava or lawn, but neither fits perfectly. However, “lav” might be a typo for lave, which is not common. Alternatively, perhaps it's meant to be lawn?

But looking closely: lav → likely intended to be lava? But that would need two letters added. Or maybe lave?

Actually, consider:
- lave = to wash (used in poetry), not common.
- lava = molten rock — more common.

But "lav" is too short. Perhaps it's lawn? Then missing n and o? That seems unlikely.

Another possibility: lave → lave is a real word, but rare.

Wait — what about lave vs lave? No.

Let's think differently:
In spelling patterns, “lav” might be intended to be lave — but still missing an 'e'? No, “lave” has four letters.

Hmm — actually, lav is a common abbreviation, but not a word. But in third grade, this may be a typo for lave or lawn?

Wait — better idea: Is it lave? But "lav" is missing one 'e'? No — "lave" is spelled L-A-V-E.

So "lav" is missing 'e' → lave.

But "lave" is not commonly used in third grade.

Alternatively, could it be lawn? Then it would need 'n' and 'o', so not just one missing letter.

But let's look at the pattern: All other words are common third-grade vocabulary.

Let’s reconsider: Could it be lava? Then missing 'a' and 'a'? No — "lav" → "lava" needs two letters.

Wait — perhaps it's lave? But that’s not a typical third-grade word.

Another possibility: lave → but maybe it's meant to be love? But that would require changing 'v' to 'o', not just adding.

Hmm.

Let’s check:
"lav" — could it be lave? Yes, but uncommon.

But wait — maybe it's lave as in “to lave the shore”? Still rare.

Alternatively, perhaps it's lawn? But that doesn’t fit.

Wait — another thought: lav might be a typo for lave, but even then, it's missing 'e'.

But here's a better idea: lave → yes, missing 'e' → lave.

But in third grade, lave is not typical.

Alternatively, maybe it's lave → but no.

Wait — perhaps it's lave → but the intended word is lave? Maybe it's lave.

But let’s look back:
1. kne → knee
2. knew → correct
3. kno → know
4. lam → lamb
5. lagh → laugh
6. law → correct
7. leve → leave
8. life → correct
9. los → lose
10. lav → ?

Notice: "lav" is likely a typo for lave or lava?

But “lava” has 4 letters — “lav” is missing 'a'? No — lava is L-A-V-A → so "lav" is missing 'a' at the end? But that would make it "lava", which requires adding 'a'.

Wait — “lav” → add 'a' → lava? That makes sense.

But “lava” is a valid third-grade word.

However, “lav” → “lava” adds one letter? No — “lava” has 4 letters; “lav” has 3 — so missing 'a' at the end? But “lava” ends with 'a', so yes.

But “lava” is pronounced “LAV-uh”, so the ‘a’ is silent? No — it’s pronounced “LAH-vuh”.

But “lav” → “lava” is plausible.

But wait — “lave” is also possible.

But let’s check the pattern:
Most of these are common words: knee, knew, know, lamb, laugh, law, leave, life, lose...

What word starts with "lav"?
- lava – yes, common in science
- lave – rare

Given the context, lava is more likely.

But “lav” → “lava” — missing 'a' at the end?

But “lava” is spelled L-A-V-A — so from “lav”, you need to add 'a' at the end? But “lav” + 'a' = “lava” — yes!

So:
- “lav” → missing 'a' → lava

But wait — “lav” → “lava” — that's adding one letter at the end.

Yes.

So answer:
- First line: yes
- Second line: lava

But is “lava” a third-grade word? Yes, especially in science contexts.

Alternatively, could it be lawn? Then missing 'n' and 'o' — two letters — less likely.

Or lave? But that’s not common.

So best guess: lava

Therefore:
- 10. lav → yes, lava

But let’s double-check:
- “lav” → “lava” — yes, missing 'a' at the end.

However, some might argue that “lav” is not a standard spelling of “lava” — but it’s clearly a missing letter.

So we’ll go with lava.

Bonus Question:

> Write the word you are having the most difficulty with on the lines.

This is subjective. For example, a student might say:
- laugh (because of the 'gh')
- knee (silent 'e')
- lava (uncommon)

But since this is a worksheet, students can write whichever they find hard.
