Lesson plan

Warm-up

5 min

Apostrophe trio: teacher shows 6 phrases on board, children sort into 3 jobs — 'don't' / 'the boy's hat' / 'the boys' hats' / 'can't' / 'the cat's bowl' / 'the cats' bowls.'

Teacher moves

Affirm each job by name
Highlight where the apostrophe sits (BEFORE the s for singular, AFTER the s for plural)

Direct instruction

13 min

Apostrophes have three jobs. Job 1: CONTRACTION — marks a missing letter (don't = do + not, the o is gone; it's = it + is). Job 2: SINGULAR POSSESSIVE — shows ONE owner (the boy's hat = the hat belonging to the boy). Job 3: PLURAL POSSESSIVE — shows MORE THAN ONE owner (the boys' hats = the hats belonging to the boys). Sound clue: 'boy's' and 'boys'' SOUND the same — the apostrophe placement is your only signal. NOW commas. Three jobs we use this term. Rule 1: in a SERIES of 3 or more — 'I like apples, oranges, and grapes.' Rule 2: BEFORE a coordinating conjunction in a COMPOUND sentence — 'I ran, and I fell.' Rule 3: AFTER a DIALOGUE TAG when a character speaks — 'She said, "Stop running."'

Key examples

Read aloud, then ask: ONE owner or MANY?

model Maria's coat is on the boys' hooks. (Maria's = singular possessive, one Maria. boys' = plural possessive, multiple boys sharing the hook bank.)

prompt Add apostrophes correctly: 'Marias coat is on the boys hooks.'
Notice TWO comma rules in one sentence — they layer.

model I packed pencils, paper, and a snack, and I left early. (Series of 3 = first two commas. Compound sentence = comma before the second 'and.')

prompt Add commas: 'I packed pencils paper and a snack and I left early.'

Checks for understanding

Where does the apostrophe go in plural possessive?
Add a comma to: 'I read the book and I loved it.'

Teacher notes

Apostrophes are the convention Grade-2 children most often get wrong — 'apple's' for 'apples' is the canonical error. The READ-ALOUD test (one owner or many?) is decisive. For commas, the compound-sentence rule is the newest; expect children to forget it for the first 3-4 drafts. Plan to spiral-review weekly. The dialogue-tag comma is a light introduction; full dialogue mechanics belong to Grade 3 Fall.
