Here is a Cultural Literacy worksheet on the concept of a prime number. This is a half-page worksheet with a one-sentence reading, which is actually two clauses separated by a semicolon, and two comprehension questions. The reading might require some simplification and editing if you are dealing with English language learners or emergent readers. That won’t be a problem as this document, like most of what you’ll find here at Mark’s Text Terminal, is formatted in Microsoft Word for the express purpose of flexibility in the teacher’s hand.
In any event, however, this is an elegantly simple worksheet on a relatively simple concept in mathematics.
