Corrected sentence: Light and fast, deer easily make their way through the thick forest.
Simple version for you: Deer are light and fast. They easily move through the thick forest.
Step-by-step explanation (for a 6-year-old):
- Don't write the animal name in all capital letters. Write deer, not DEER.
- The comma after "Light and fast" is good because those words come before the rest of the sentence.
- "Deer" is a special word: it is the same when we mean one deer or many deer. We say "deer make" or "deer are" depending on the sentence.
- "Thick forest" is easier to understand than "thickets." "Thickets" is okay, but younger children might know "bushes" or "thick forest" better.
If you'd like, try saying the sentence out loud: it should sound smooth and not shouty (no ALL CAPS!).
