Navigate through the clouds by finding words like 'cute' and 'flute' to help the bird reach its nest.

Explanation:
We need to find all the words that have the long u sound — that is, the sound like in *“blue”*, *“true”*, or *“cute”*. The long u sound is usually spelled as u, ue, ew, or sometimes ui or oo — but in this worksheet, we’re looking for words where the *u* makes the long /uː/ sound (like “you”), not the short /ʌ/ sound (like in *“cup”*).

Let’s go row by row and check each word:

1. glum → /ɡlʌm/ — short u → ✘
2. spun → /spʌn/ — short u → ✘
3. fume → /fjuːm/ — long u (the “u” says “you”) → ✔
4. duck → /dʌk/ — short u → ✘
5. slug → /slʌɡ/ — short u → ✘

6. glue → /ɡluː/ — long u (ends in “ue”) → ✔
7. tube → /tjuːb/ — long u (“u” says “you”) → ✔
8. flew → /fluː/ — long u (“ew” = long u) → ✔
9. stuff → /stʌf/ — short u → ✘
10. lunch → /lʌntʃ/ — short u → ✘

11. cute → /kjuːt/ — long u (“u” says “you”) → ✔
12. pun → /pʌn/ — short u → ✘
13. lung → /lʌŋ/ — short u → ✘
14. drum → /drʌm/ — short u → ✘
15. lump → /lʌmp/ — short u → ✘

16. use → /juːz/ — long u (“u” says “you”) → ✔
17. brush → /brʌʃ/ — short u → ✘
18. cue → /kjuː/ — long u (“ue” = long u) → ✔
19. tune → /tjuːn/ — long u → ✔
20. true → /truː/ — long u (“ue” = long u) → ✔

21. puke → /pjuːk/ — long u → ✔
22. flute → /fljuːt/ — long u → ✔
23. stew → /stjuː/ — long u (“ew” = long u) → ✔
24. punt → /pʌnt/ — short u → ✘
25. grew → /ɡruː/ — long u (“ew” = long u) → ✔

26. mutt → /mʌt/ — short u → ✘
27. plus → /plʌs/ — short u → ✘
28. crush → /krʌʃ/ — short u → ✘
29. bunt → /bʌnt/ — short u → ✘
30. mute → /mjuːt/ — long u → ✔

31. rude → /ruːd/ — long u (“ue” = long u) → ✔
32. dude → /djuːd/ — long u → ✔
33. chew → /tʃuː/ — long u (“ew” = long u) → ✔
34. fluke → /fluːk/ — long u → ✔
35. crew → /kruː/ — long u → ✔

36. threw → /θruː/ — long u (“ew” = long u) → ✔
37. rung → /rʌŋ/ — short u → ✘
38. fuss → /fʌs/ — short u → ✘
39. just → /dʒʌst/ — short u → ✘
40. thud → /θʌd/ — short u → ✘

Now let’s list all the ✔ words:

- fume
- glue
- tube
- flew
- cute
- use
- cue
- tune
- true
- puke
- flute
- stew
- grew
- mute
- rude
- dude
- chew
- fluke
- crew
- threw

That’s 20 words.

Double-check a few tricky ones:
- stew, grew, chew, crew, threw — all use *ew* = long u ✔️
- fume, use, cute, puke, dude, mute, rude, fluke — *u* followed by consonant + *e* or just *u* with /j/ glide = long u ✔️
- glue, cue, tune, true — *ue* ending = long u ✔️
- tube, flute — *u* before consonant + *e* (silent e rule) = long u ✔️

No mistakes found.

Final Answer:
fume, glue, tube, flew, cute, use, cue, tune, true, puke, flute, stew, grew, mute, rude, dude, chew, fluke, crew, threw
