Side-by-side illustration of the SAME Grade-2 multicultural child: LEFT panel — slumped on a beanbag with a phone, texting a friend, speech bubble 'hey wanna play?'; RIGHT panel — at a school desk writing a formal letter with neat handwriting, speech bubble 'Hello, would you like to play this afternoon?' Caption: 'Same kid. Different audience. Different register.' Print-ready, watercolor style.

Direct instruction

13 min

Same idea, different audience, different LANGUAGE. INFORMAL English fits friends, family, and texts. Cues: 'hey', 'gonna', 'kinda', 'lol', 'yeah', contractions everywhere, short sentences, slang. FORMAL English fits letters, school assignments, and unfamiliar adults. Cues: 'Hello', 'going to', 'kind of', 'Yes', few contractions, longer sentences, no slang. NEITHER IS WRONG. The audience picks the register. Watch: 'Hey wanna play later?' (informal — friend) vs. 'Hello, would you like to play later this afternoon?' (formal — adult or unfamiliar friend). Same idea, different audience.

Key examples
  • Notice the IDEA is the same. Only the register changed.
    model FORMAL: 'Hello Lee, that movie was excellent. You should watch it.' Notice: hey→hello, sick→excellent, gotta→should, you gotta→you should.
    prompt Translate INFORMAL → FORMAL: 'Hey Lee, that movie was sick, you gotta see it.'
  • Notice both versions are legitimate — they fit different audiences.
    model INFORMAL: 'Hey Mr. P, you should check out the new shark book!' (assuming a friendly relationship). Notice the GREETING changes, and 'recommend' becomes 'check out.'
    prompt Translate FORMAL → INFORMAL: 'Dear Mr. Patel, I would like to recommend the new shark book.'
Checks for understanding
  • Name 3 cues that say 'informal.'
  • Which version would you send to your principal?

Formal vs. informal English anchor chart (L.2.3.a): two columns side by side — INFORMAL ('hey', 'gonna', 'kinda', 'lol', 'wanna', 'yeah', 'thx', 'u') | FORMAL ('hello', 'going to', 'kind of', 'that is funny', 'want to', 'yes', 'thank you', 'you') with example pair contexts: text-to-friend vs. letter-to-principal. Print-ready 11x17.

Guided practice

12 min
Tasks
  • Sort 8 message strips into FORMAL and INFORMAL columns with a partner.
    scaffold MG-9 anchor + audience-icon cards
  • Translate one INFORMAL message you sort into formal English on paper.

Formative assessment

3 min
Exit ticket
  • Write the SAME idea twice: once as a text to a friend, once as a note to your principal. Same idea, different register.
scoring Both versions same idea + clear register difference = mastery; one version weak = practicing; both same register = reteach.

Closure

2 min
Moves
  • Hold up your two-version writing.
  • Predict: tomorrow we add the counter move to our opinion pieces.

Homework

10 min
Tasks
  • Listen for one INFORMAL phrase an adult uses tonight (yeah, gonna, kinda). Write the phrase + the audience the adult was talking to.

Teacher notes

Some children treat formal English as 'correct' and informal as 'wrong' — this is a teachable misconception. The audience-determines-register frame is the entire point of L.2.3.a. Resist correcting children's informal speech in casual settings; instead, USE the lesson to give them metalinguistic awareness. Plan to revisit when writing the formal opinion letter in lesson 20.
