Sure! Let’s solve the worksheet “Spot the Prefix!” step by step.

## 🧠 What is a Prefix?
A prefix is a group of letters added to the beginning of a word to change its meaning. Common prefixes include: *un-, dis-, mis-, re-, pre-, im-, in-, ab-, en-, etc.*
---
# ✔ Part A: Circle the word with a prefix.
We’ll go one by one and identify which word has a prefix.
---
→ disconnect = “dis-” + “connect” → “dis-” is a prefix meaning “not” or “opposite of”
✔ Circle: disconnect
---
→ abnormal = “ab-” + “normal” → “ab-” means “away from” or “not”
✔ Circle: abnormal
---
→ improper = “im-” + “proper” → “im-” is a variation of “in-”, meaning “not”
✔ Circle: improper
---
→ careless = “care” + “-less” → Wait! “-less” is a suffix, not a prefix.
But look again: “relax” = “re-” + “lax” → “re-” means “again” → Prefix!
“extend” = “ex-” + “tend” → “ex-” means “out” → Also a prefix!
Wait — the instruction says “circle the word with a prefix” — implying one per row. But multiple words may have prefixes!
Let’s check all:
- relax → prefix “re-”
- extend → prefix “ex-”
- careless → suffix “-less” (not prefix)
- bright → no prefix
So both “relax” and “extend” have prefixes. But since it says “the word” (singular), we should pick one. Usually, worksheets expect the most obvious or first correct answer.
✔ Circle: relax (or extend — both are correct, but let’s go with relax as it’s first)
> 💡 Note: If your teacher allows multiple, you could circle both. But for standard answers, we’ll pick relax.
---
→ interact = “inter-” + “act” → “inter-” means “between” → prefix
✔ Circle: interact
---
## ✔ Final Answers for Part A:
1) disconnect
2) abnormal
3) improper
4) relax (or extend — both valid, but relax is more commonly taught first)
5) interact
---
# ✔ Part B: Underline the word with a prefix, in each sentence.
We underline the entire word that contains a prefix.
---
→ unsafe = “un-” + “safe” → “un-” is a prefix meaning “not”
✔ Underline: unsafe
---
→ misbehaves = “mis-” + “behaves” → “mis-” means “wrongly”
✔ Underline: misbehaves
---
→ enlarged = “en-” + “large” + “-ed” → “en-” is a prefix meaning “to make”
✔ Underline: enlarged
---
→ disappear = “dis-” + “appear” → “dis-” means “away” or “reverse”
✔ Underline: disappear
---
→ repainted = “re-” + “painted” → “re-” means “again”
✔ Underline: repainted
---
## ✔ Final Answers for Part B:
1) unsafe
2) misbehaves
3) enlarged
4) disappear
5) repainted
