What L.4.4 Means in Plain English
Fourth graders work out an unknown word three ways: clues in the sentence (a definition, an example, a restatement), Greek and Latin parts like tele, photo and graph, and a dictionary or glossary for the exact meaning and the pronunciation. They pick whichever strategy the word calls for.
Third graders (L.3.4) used sentence clues, common affixes like un- and -less, and known root words, as company helps with companion. Fourth grade adds Greek and Latin roots and the pronunciation guide. Fifth grade (L.5.4) adds cause-and-effect and comparison clues, with roots like photo in photosynthesis.

L.4.4 Worked Example

Common Mistakes with L.4.4
Splitting into English words
“Manuscript is a man’s script,” or “carpet is a pet in a car”
Try this: Teach a small set of roots on cards (manu, script, port, graph, tele) and have students hunt for them before guessing.
Skipping the sentence
A student defines a word from its parts and never checks whether that meaning fits
Try this: Require one last step for every word: put the meaning back in the sentence and read it aloud to test it.
Taking the first dictionary meaning
For draft in “a cold draft came under the door,” a student copies “a first version of a piece of writing”
Try this: Have students read every numbered meaning and choose the one that fits the sentence, then say why it fits.
