This question tests 1st grade capitalization of names and dates (CCSS.L.1.2.a: Capitalize dates and names of people). Capital letters (big letters, uppercase) are used for specific, special words; we ALWAYS capitalize names of people - both first names (Emma, Jamal, Sofia) and last names (Smith, Brown, Rodriguez); we also ALWAYS capitalize days of the week (Monday, Tuesday, etc.) and months of the year (January, February, etc.); we do NOT capitalize common nouns - regular words for things like cat, dog, book, ball, house (unless they start a sentence). The sentence contains a month that needs a capital letter; 'june' is part of a date - a specific month of the year. Choice B is correct because the month 'june' needs to be capitalized as 'June' since months are proper nouns and always get capital letters. Choice A represents over-capitalization; students make this error because they might confuse 'birthday' as special and capitalize it, but it's a common noun unless it's a specific name. To help students, connect months to birthdays like 'My birthday in June' and practice sorting 'June' (proper - specific month) vs 'month' (common - any month); use highlighters for months. Make an anchor chart: 'Always Capitalize: Months (June), Days (Monday), Names'; watch for forgetting month capitals or capitalizing common words like 'birthday party'.
