m’Pouvez-vous m'aider avec ces mots ?

You'd need a structure like "pouvez-vous..." ("can you"), otherwise the sentence wouldn't make sense
Space before and after ! ? : ; « » %

1. lL’importance d’e l'école ¶
2.

Definite, since you're talking about school as a general concept => L'école

D’autre part, ceuxrtains pensent qu’ils ont tort ¶
3. lLa plupart de/s(?)s

I guess you meant "some (people)"? In this case it would be "certains"
la plupart DES [de+les], you're taking a part from a definite group here

4. permet aux enfants de beaucoup apprennentdre sûur… ¶
5. le système éducationf souvent [pénurie ?] les compétences essentielles ¶
6. les enfants apprennent à la maison ¶
7. en expofaisant lesdécouvrir aux enfants à lesde neouvelles cultures ¶
[8. quel donner aux enfants plus possibilités ?]¶
9. éduquer les enfantsfaire l'école à la maison ont la des avantages

You need a conjugated (present form) => les enfants SE SENTENT

permettre d'apprenDRE (infinitive)

I guess you meant "about", so it would be "sur". "sûr" (with accent circonflexe) means "sure" or "safe"

adjective ("éducatif"). "Éducation" is only a noun, so you would need "de" to connect it to the previous noun, but an adjective is better here

"pénurie" is a noun, not a verb, so I don't know what you meant here

I don't know the context of 7, but "faire découvrir" would definitely be more positive than "exposer"

some new cultures => DE nouvelles cultures (indefinite)

I didn't understand 8

If you meant "homeschooling" for 9, "faire l'école à la maison" would be a more accurate pick, since "éduquer" in French has a much broader meaning than just instructing, giving information

You're subject is a verbal phrase ("éduquer les enfants") so a singular agreement applies => A

has some advantages = DES avantages
