All of those sentences are incorrect. After you have made the corrections that you believe are needed, please repost and a teacher will be happy to make corrections and further suggestions.

To correct the sentences, we need to ensure proper agreement and use of pronouns. Here are the corrected versions:

1. Every one of the students I spoke to said they liked their math class.
Explanation: The pronoun "their" should match the plural noun "students."

2. If a person loses their jacket, they can check the lost and found.
Explanation: The pronoun "their" should match the singular noun "person." To maintain gender neutrality, "they" can be used as a gender-neutral pronoun.

3. Each of the boys likes to go out for ice cream after he wins a game.
Explanation: "Each" signifies individuality, so the pronoun "he" should be singular to match "each."

4. My mom gave my sister and me money to spend at the mall.
Explanation: "I" should be changed to "me" because it is an object pronoun, along with "my sister."

5. We kids think there is too much homework.
Explanation: Replacing "Us" with "We" makes the subject pronoun agree with the verb "think."

6. David let Mark and him copy science notes.
Explanation: "He" should be changed to "him" because it is the object of the verb "let."
