What L.6.6 Means in Plain English
Sixth graders learn two kinds of words and use them accurately: academic words that work in every class, like evidence, contrast and consequently, and subject words like irrigation or ratio. When a word matters to what they read or say, they track it down instead of skipping it.
Fifth graders (L.5.6) learned academic and subject words, including linking words like however and although. Sixth grade expects students to gather vocabulary on their own when a word is important, from the text, a glossary or a dictionary. Seventh grade (L.7.6) carries the habit to words like photosynthesis.
L.6.6 I Can Statements
- I can use unit words like irrigation correctly in my own sentences.
- I can use academic words like consequently to connect my ideas.
- I can look up a word when it matters to understanding.
L.6.6 Worked Example
A social studies answer with the right ideas and none of the right words, then the same ideas said precisely.
Revise this answer to “Why did farming villages in Mesopotamia grow into cities?” Use the unit words irrigation and surplus, and an academic word that shows cause and effect.
Common Mistakes with L.6.6
Talking around the word
“The water things they dug,” when the unit word is irrigation canals
Try this: Post the unit word list beside the prompt, and have students replace each vague noun with the word it stands for.
The word used, but wrong
“Irrigation is when it rains a lot.”
Try this: Ask for a sentence that shows the meaning, like “Without irrigation, fields far from the river stayed dry,” and check it with a partner.
Reading past the word that matters
A student skips ziggurat three times and can’t say what the paragraph described
Try this: Teach a stop rule: when one word blocks a whole paragraph, look it up in the glossary before reading on, and log it.
