This tests CCSS.L.2.3.a (comparing formal and informal uses of English). Formal English is language we use in school (especially with teachers and in classroom), when meeting new people, and when talking to adults we don't know well. It uses complete words (cannot instead of can't, want to instead of wanna), polite phrases (please, thank you, excuse me, may I), and respectful tone. Examples of formal: "Hello," "Good morning," "Yes, please," "May I please use the restroom?" "That's interesting." Informal English is language we use with friends and family we know well, at recess, and in casual situations. It uses contractions (can't, wanna, gonna), casual words (yeah, cool, hey, awesome), and relaxed tone. Examples of informal: "Hey!" "Yeah!" "Wanna play?" "Can I go?" "That's so cool!" Both formal and informal are correct - we just use them in different situations. Using formal language with teachers shows respect; using informal with friends shows comfort and friendliness. Good communicators naturally switch between formal and informal depending on who they're talking to and where they are. Choice A is correct because it correctly identifies formal language with 'May I please use the restroom?', which is polite and appropriate for asking a teacher in class. Formal language is appropriate with teacher/principal/unfamiliar adults and in classroom. This shows understanding that we adjust our language based on the situation and who we're talking to. Choice B shows confusion about formality by suggesting an informal, urgent phrase that doesn't match the respectful tone needed for a teacher. Second graders sometimes think "Hey" is okay to say to principal, don't understand why they need to use "May I" with teacher, think formal language is "too fancy," think informal is rude instead of just casual, don't recognize the difference between formal and informal, think you should always talk the same way to everyone. To help students: Create comparison chart: FORMAL (When: With teacher, principal, adults; In classroom; Meeting new people) (Examples: Hello, Good morning, Yes please, No thank you, May I please, Excuse me, I would like, I am going to) | INFORMAL (When: With friends, family; At recess, home; Casual time) (Examples: Hey, Hi, Yeah, Nope, Can I, Wanna, Gonna, See ya). Role play: Practice switching - "How would you ask your teacher?" then "How would you ask your friend?" Same message, different formality. Teach key contrasts: Greetings (Hey/Hi vs Hello/Good morning), Yes/No (Yeah/Nope vs Yes/No), Requests (Can I vs May I please), Want to (Wanna vs Want to/Would like to), Going to (Gonna vs Going to/Am going to). Situation cards: Give scenarios ("talking to principal," "playing with friend at recess") and students identify formal or informal. Practice converting: Give informal sentence, students make it formal ("Wanna play?" → "Would you like to play?") and vice versa. Emphasize context: Not that one is right and one is wrong - both are correct in their situations. Model: Teacher switches language appropriately ("Hey, let's go!" at recess → "Please line up quietly" in classroom). Explain purpose: Formal shows respect and politeness, informal shows comfort and friendliness. Discuss real examples: Notice in books/videos how characters talk differently to different people. Watch for: students who think informal is rude (it's not - just casual), students who use informal with teachers ("Hey Mrs. Johnson"), students who think formal is "too fancy" (it's just respectful), students who don't recognize difference ("They're the same"), students who can't match language to situation (using formal with friends at recess).

This tests formal language with new adults. 'Hello. It is nice to meet you' sounds polite. We use our best manners with adults.

We speak differently at home and school. 'I have to go' uses all the words. 'Gotta' is a short, casual word.
