Question

Should there by any dashes or hyphens here?

should it be like:

???

Answer 1

No hyphens should be used in these constructions.

You can look up these words in a dictionary -- such as Dictionary.com -- to find the correct spelling/hyphenation.

Answer 2

Hyphenate age-group, but not any others.

Answer 3

so age-group or no ?

Answer 5

I believe it makes a difference whether you use it as a noun or an adjective.

Examples:

Sandy attends a preschool with her age group.

The materials used in that school are age-group appropriate.
