Learn French: Ce sont des enfants.

In French, the expression for "it is" is c'est. When you need to say "these are" or "they are" before a noun, you use ce sont. The word sont is the plural "are", but the pronoun ce stays singular. You would only use the plural ces directly in front of a noun, like ces enfants (these children).

Why do we need des in this sentence when English just says "children"?

In English, we can just say "These are children" without a word before "children". In French, nouns almost always need an article (little words like a, the, or some). des is the plural indefinite article. It acts like the plural of un or une. You have to include it, even if it doesn't translate to anything in the English sentence!

Are the s letters at the end of des and enfants pronounced?

The s at the end of enfants is completely silent. However, the s in des is pronounced! Because enfants starts with a vowel, the s in des links to it with a Z sound. This sound link is called a liaison. You pronounce the two words together smoothly.
