Sentence Combining — All Five Joining Words at Once
- Students combine sentence pairs using the most appropriate of AND, BUT, OR, SO, BECAUSE.
- Students explain their conjunction choice in one sentence.
Lesson plan
Warm-up
4 minFive-card flash drill: teacher reads a pair, class holds up the best card.
- Affirm correct cards with brief one-word explanation ('cause!', 'choice!')
Direct instruction
10 minWe have a writer's toolbox of FIVE joining words now. Today is the day we practice picking the BEST one. There is often more than one right answer — but the BEST answer is the one that fits the meaning best. Watch: 'I was hungry. I ate a snack.' Could be AND (I was hungry and I ate a snack — true!). Could be SO (I was hungry so I ate a snack — better, shows cause). Could be BECAUSE (I ate a snack because I was hungry — also better, flipped order). The BEST is SO or BECAUSE because the relationship is cause-effect.
-
AND would work but SO captures the relationship.model Best: 'The sky was dark, SO we went inside.' (cause-effect)prompt Combine: 'The sky was dark. We went inside.'
-
AND would also work but suggests both; OR captures the either-ness.model Best: 'I wanted apple OR orange.' (choice)prompt Combine: 'I wanted apple. I wanted orange.'
- Pair: 'I have a dog. I have a cat.' Best word? (AND)
- Pair: 'My foot was tired. I sat down.' Best word? (SO or BECAUSE)

Decision flowchart anchor poster. Top: 'How are these two sentences related?' Five branches: 'They add up' → AND. 'They contrast' → BUT. 'They are a choice' → OR. 'One causes the other (cause first)' → SO. 'One gives the reason for the other (result first)' → BECAUSE. Each branch ends in a small example sentence. Colors match the conjunction-card system. Print-ready 11x17.
Guided practice
15 min-
Pair drill: 10 sentence pairs. Each pair picks the best conjunction, writes the combined sentence, then writes one sentence explaining their choice.scaffold MG-2 anchor poster visible; conjunction cards on table

Whole-class debrief: pairs share one tricky pair where they considered two options.

Interactive
Physical / non-image
On-screen sentence-combining game. A sentence pair appears top of screen. Child taps one of five colored buttons at bottom (AND yellow, BUT red, OR blue, SO orange, BECAUSE purple). On choice, the joining word slides into place and the combined sentence reads aloud. A 'why?' icon offers a brief audio explanation. 20 sentence pairs in random order; child can replay missed ones.
Formative assessment
3 min- Combine and explain: 'I tried hard. I made the team.' (AND? BUT? OR? SO? BECAUSE?)
- Why did you pick that word?
Closure
1 min- Author's chair: one pair shares the BEST sentence of the day.
Homework
8 min- Write three pairs of sentences from your day and combine each with the best conjunction.

Teacher notes
First synthesis lesson — children must now ACTIVELY CHOOSE rather than be told. Expect lots of AND-as-default; gently push back: 'Yes, AND works. Is there a better one?' Hochman's research shows sentence-combining is the single most effective grammar instruction; do not skip the explanation step.
