The Standard

Provide introduction with a topic sentence.

South Dakota English Language Arts Standards (2025)

Teacher's field guide

What Students Need to Do: Students write an opening that names what their piece will explain. They put a clear topic sentence before the facts and details.
What Mastery Looks Like: For a piece about school gardens, a student might begin, 'Our school garden grows food and flowers.' The sentences that follow give facts about the garden.
Common Misconceptions: Some students start with one small fact, such as 'Carrots grow underground,' when their whole piece is about gardens. Others write 'I will tell you about something' without naming the topic.
How to Assess It: Ask students to write the first sentence of a paragraph about a school garden. Have them underline the words that tell the reader what the paragraph will be about.

Lesson moves

Give pairs sentence strips about a school garden; have them choose an opening, place it first, and arrange two matching facts below it.
Show 'Our garden is fun' and 'Our garden grows vegetables for lunch'; ask which better opens a piece about growing food and why.
Play Topic Sentence Match: students pair four topic cards with opening sentences, then explain why each opening fits its card.
Show a cafeteria menu with carrots; students write a first sentence for a note explaining how carrots grow.
