"Th" Book: Cut and paste pictures that start with the "th" sound into the book.

Let’s go step by step to solve this problem.

We are asked to help finish the “Th” book. That means we need to find pictures that start with the letters “th” — like “thumb,” “thermometer,” or “three.”

Look at all the pictures below the book:

1. A hand pointing → that’s a thumb ✔ (starts with “th”)
2. Scissors → starts with “s” ✘
3. Tricycle → starts with “t” but not “th” ✘
4. Megaphone → starts with “m” ✘
5. Thermometer → starts with “th” ✔
6. Number 3 → that’s three ✔ (starts with “th”)
7. Water bottle → starts with “w” ✘
8. Stopwatch → starts with “s” ✘
9. Paintbrush → starts with “p” ✘
10. Cake → starts with “c” ✘

So, the pictures that start with “th” are:
- Thumb
- Thermometer
- Three

That’s 3 pictures total.

Now, the instruction says: “Cut out and paste the pictures that start with the letters ‘th’ into the book.”

So, you would cut out those three pictures and glue them inside the open book on the page.

Final Answer:
Cut out and paste the pictures of the thumb, thermometer, and the number 3 (three) into the book.
