About this worksheet

Two-part scientific names. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can split a scientific name into genus and species and write it with the genus capitalized.
  • I can use the genus to find close relatives, and say why common names can mislead.
  • I can read a name's meaning from a word-part key.

Standard: none (IXL parity)

Words to know

scientific name: A two-part name for one kind of living thing: genus, then species

genus (genera): A group of closely related species; the first word of the name

species word: The second word; it is not a name by itself

common name: An everyday name, which can differ from place to place

word part: A piece of a Latin or Greek word with its own meaning

Common mistakes

Your child mixed up which word is the genus. The genus comes first and has the capital letter; the species word comes second.

Your child capitalized the wrong word. Only the genus starts with a capital: Panthera leo, never panthera Leo.

Your child treated the second word as the whole name, or matched names by their second word. The species word only works with its genus.

Questions parents ask
