Here are the corrected sentences, written simply:
- The hump on a bison’s shoulders is a bunch of strong muscles that helps it hold up its big, heavy head.
- The shoulder hump is a bunch of muscles that helps the bison lift and hold up its big head.
- The bison’s shoulder bump is made of muscles that help it keep its big, heavy head up.
- Just like cows, bison walk in groups and eat grass, shoots, and leaves.
Why I changed them:
- I used simpler words like bunch and big so the sentences are easier to read.
- I changed bite off to eat because eat is clearer for a young reader.
- I fixed is muscle to is made of muscles so the sentence is grammatically correct.
- I made small verb fixes so each sentence sounds natural and correct.
Great job! These sentences are now clear and easy for a 6-year-old to understand.
