Nice sentences! Here are corrected, simple versions you can use:
- Quack! The duck calls her ducklings to the pond.
- Ribbit! The frog jumps away.
If you want the sound inside the sentence instead of as an exclamation, you can write:
- The duck goes 'quack-quack' to call her ducklings to the pond.
- The frog goes 'ribbit' before it jumps away.
Easy tips:
- Start each sentence with a capital letter (Quack, The).
- Put a period or exclamation mark at the end.
- Write the animal sound as a word like quack or ribbit.
