Skills targeted
Objectives
  • Students orally use BECAUSE, BUT, and SO to join sentences.

Lesson plan

Warm-up

3 min

Hochman 'because, but, so' oral routine: 'I went to bed BECAUSE ___.' 'I went to bed BUT ___.' 'I went to bed SO ___.'

Teacher moves
  • Model each completion
  • Notice: each conjunction takes a different kind of continuation

M-K-S-GR-11-B Video Physical / non-image

45-second video. Teacher and a small group of children: teacher says 'I went to school BECAUSE ___.' Three children complete in turn. Same starter with BUT, then SO. Captions show each completion. Demonstrates the routine for daily practice.

Direct instruction

10 min

Three more joining words. BECAUSE gives a REASON ('I was hungry BECAUSE I didn't have breakfast'). BUT shows a DIFFERENCE ('I wanted to play BUT it was raining'). SO shows a RESULT ('I was tired SO I went to bed'). Each one tells the reader a different thing.

Key examples
  • Gives the reason for being happy.
    model 'I was happy because my friend visited.'
    prompt 'I was happy ___.' Try BECAUSE.
  • Shows the difference.
    model 'I was happy but my brother was sad.'
    prompt Same start: try BUT.
  • Shows what happened next.
    model 'I was happy so I sang a song.'
    prompt Same start: try SO.
Checks for understanding
  • Which word gives a reason? (because)
  • Which shows a difference? (but)
  • Which shows a result? (so)

M-K-S-GR-11-A Chart Physical / non-image

Anchor chart 'Joining Words That Show Meaning'. Three boxes: BECAUSE (with a question-mark icon and 'gives a REASON'); BUT (with a contrast/two-sided arrow icon and 'shows a DIFFERENCE'); SO (with a result/forward arrow icon and 'shows what HAPPENED NEXT'). Each box has one example sentence using a single base prompt 'I was happy' completed three different ways.

Guided practice

12 min
Tasks
  • Partner Hochman routine: Partner A gives a sentence-starter; Partner B completes with BECAUSE, BUT, SO.
    scaffold Conjunction cards visible.
  • Sentence-strip joining: use scissors and tape to join with the right conjunction.
    scaffold Pre-printed strips matched to the right conjunction.
  • Write one compound sentence using BECAUSE.
    scaffold Frame: '___ because ___.'

Formative assessment

2 min
Exit ticket
  • Use BECAUSE in a sentence about your favorite food.
  • Use BUT in a sentence about today's weather.
  • Use SO in a sentence about what you did at recess.
scoring 3/3 used correctly = mastery; 2/3 = practicing; 0-1 = reteach with sentence frames.

Closure

Moves
  • Chant: 'Because = reason. But = different. So = result.'

Homework

5 min
Tasks
  • At dinner, listen for someone using BECAUSE, BUT, or SO. Tell us about it tomorrow.

Differentiation

Scaffolds
  • Reduce to one conjunction at a time
  • Sentence frames
  • Adult co-construction
Extensions
  • Use all three in one paragraph
  • Write a sentence with two conjunctions: 'I was hungry BECAUSE I didn't eat breakfast SO I ate two apples.'
  • Find these conjunctions in class books
English Learners
  • Translation of each
  • Note: some languages use a single particle for 'because/so'
  • Bilingual conjunction cards
Ieps 504s
  • AAC
  • Pre-built options

Teacher notes

This is the bedrock of compositional complexity. The 'because, but, so' routine compounds (no pun intended) into mature compositional writing in upper grades. Plan to integrate the routine 3x/week into workshop minilessons throughout Spring.
