Nice sentence! Here is a clear correction and a simple explanation.
Correct sentence (two good options):
Zebras have black and white stripes.
or
Zebras are black with white stripes.
Both sentences are grammatically correct. "Zebras are black with white stripes." is fine, but many people like the shorter, clearer sentence "Zebras have black and white stripes."
Things to check:
- Capital letter: Start the sentence with a capital letter: "Zebras".
- Spelling: You wrote "chcek" — the correct word is "check."
- Punctuation: End the sentence with a period: "."
- Subject and verb: "Zebras" is plural, so use "are" (or use "have" as in the corrected sentence).
Try this: Write another sentence about an animal, for example: "Giraffes have long necks."
