Why do some adjective pairs take a comma and others do not?

Because some pairs describe the noun separately and some stack. In a cold, damp stairwell both words describe the stairwell. In a bright red jacket, bright describes red, so the two work as one unit and the comma would split them.

What are the two tests again?

Put and between the adjectives, and then swap their order. If the phrase survives both, the adjectives are coordinate and take a comma. If either version sounds wrong, leave it out.

Does this ever apply to three adjectives?

Yes, and then you get two commas: a steep, narrow, slippery stretch. The last adjective still gets no comma between it and the noun.

7th grade commas between coordinate adjectives

7th grade commas between coordinate adjectives worksheets

Coordinate adjectives are two or more adjectives that describe the same noun separately and equally. They take a comma between them. You can spot them with two tests: the adjectives still make sense with and between them, and they still make sense in the opposite order. Adjectives that fail either test take no comma.

How to teach this

Run both tests out loud, in the same order, every time. Say the phrase with and, then say it backward. A cold and damp stairwell, a damp cold stairwell: both fine, so the comma goes in. A bright and red jacket, a red bright jacket: both wrong, so it stays out. Doing the tests aloud matters more than it sounds, because the ear catches what the eye misses. The error worth naming separately is the comma before the noun, which is the one students add when they treat the adjectives as a list.

Watch for: Never put a comma between the last adjective and the noun. A long, muddy, trail is wrong even when the first comma is right. Adjectives of number, material, and color usually attach to the noun as a unit, which is why two wooden benches and a bright red jacket take no comma. Both tests have to pass. If the pair fails either the and test or the swap test, leave the comma out.
