Th digraph worksheet - Free Printable

Let’s solve this step by step.

We are looking for words that have the “th” sound — like in “think” or “this”. These are called digraphs because two letters (t and h) make one sound together.

First, let’s name each picture:

Top row:
1. Fish → no “th”
2. Thumbs up → “thumb” has “th”!
3. Tooth → “tooth” has “th”!
4. Tree → no “th”

Bottom row:
5. Tissue box → “tissue” starts with “t”, but not “th”
6. Number 3 → “three” has “th”!
7. Dolphin → no “th”
8. Spool of thread → “thread” has “th”!

Wait — let’s double-check:

- Thumb ✔ (th)
- Tooth ✔ (th)
- Three ✔ (th)
- Thread ✔ (th)

Now check the others again to be sure:

- Fish ✘
- Tree ✘
- Tissue ✘ (it’s “tish-oo”, no “th”)
- Dolphin ✘

So we have four “th” words: thumb, tooth, three, thread.

That means the other four go in “not th words”: fish, tree, tissue, dolphin.

Final Answer:
th words: thumb, tooth, three, thread
not th words: fish, tree, tissue, dolphin
