Two Sentences Can Become One — Joining with AND

Skills targeted
Objectives
  • Students combine two simple sentences into one compound sentence using 'and'.
  • Students identify which pairs of simple sentences make sense to join with 'and' (related topic) versus those that don't.

Lesson plan

Warm-up

5 min

Oral sentence-combining: teacher says two sentences aloud ('I went to the park. I played on the slide.'); class chorally combines with 'and'.

Teacher moves
  • Use exaggerated PAUSE between the two simple sentences to make the boundary clear
  • Repeat with 5 pairs at increasing distance from child's daily life

Top-down camera on a desktop. Two paper sentence strips are visible: 'I went to the park.' and 'I played on the slide.' A hand slides a yellow AND card between them. Voiceover: 'Two sentences about the same idea — let's JOIN them.' Final shot: the combined strip 'I went to the park AND I played on the slide.' with one period circled. Caption track on.

Direct instruction

12 min

In Fall we wrote one sentence at a time. Today we learn a writer's trick — when two sentences talk about the same idea, we can JOIN them. Our joining word today is AND. AND means 'plus' — it adds. Watch: I clapped. + I cheered. = I clapped AND I cheered. The two periods become ONE period. The first capital STAYS; the second sentence's capital becomes a lowercase letter.

Key examples
  • Notice: one period at the very end, one capital at the very start, AND in the middle. No comma before AND in Grade 1 — that's a Grade 4 move.
    model I like apples AND I like pears.
    prompt Combine: I like apples. I like pears.
  • 'The cat' got a lowercase t because it is no longer the start of its own sentence.
    model The dog barked AND the cat hid.
    prompt Combine: The dog barked. The cat hid.
Checks for understanding
  • Does this work? 'I ate breakfast and the moon is round.' (No — unrelated topics)
  • Where is the capital in a compound sentence? (Only at the very beginning)

Side-by-side illustration. Left: two short paper sentence-strips with a period at the end of each, slightly apart. Middle: a yellow AND card slides between them, the periods on the first strip morph into a comma-less join. Right: one long combined sentence strip with a single period at the end. Style: clean diagram, arrows, primary colors (yellow AND, blue strips).

Guided practice

13 min
Tasks
  • Pair up. Each pair gets two sentence strips. Combine on the third strip using your AND card.
    scaffold Sentence strips for first three: 'I see a bird.' / 'I see a tree.' '
  • Hochman fragment-to-sentence drill — teacher gives a phrase fragment ('the red ball'), child writes a sentence, then partners up to combine two sentences with AND.

Formative assessment

4 min
Exit ticket
  • Combine these two sentences with AND: 'The sun is hot. The sand is hot.'
  • Write one compound sentence from your own life using AND.
scoring Both correct = mastery snapshot for L.1.1.g; one correct = practicing; zero = reteach.

Closure

1 min
Moves
  • Whisper to your partner: 'Today I made TWO sentences become ONE.'

Homework

8 min
Tasks
  • Listen at home for an AND sentence. Write it down (or have an adult write it as you say it). Bring tomorrow.

Differentiation

Scaffolds
  • Pre-printed sentence strips for combining (the writer only adds AND and one period)
  • Color the AND card yellow in every example to anchor visual
  • Oral-only option: combine in speech, partner writes
Extensions
  • Combine three short sentences with two ANDs and discuss why it starts to sound choppy (sets up the next lesson).
  • Find an AND in a mentor text (Yangsook Choi 'The Name Jar') and discuss why the author joined those two ideas.
English Learners
  • Bilingual conjunction card (AND/Y for Spanish, AND/AT for Tagalog, AND/HE for Mandarin)
  • Repeat oral sentence-combining drill 2x more
Ieps 504s
  • Sentence-strip manipulation only — no independent writing for week-1 IEP children
  • Extra physical AND card to hold

Teacher notes

Critical lesson — sets up the entire Spring compound-sentence arc. Do not skip oral combining; children need to HEAR the join before they can write it. The Grade-1 comma-before-AND rule is OUT — children will be confused enough without it. Reserve that for Grade 4. Watch for the 'and-and-and' run-on bug to emerge as children get excited; address gently and tell them tomorrow's lesson is the cure.
