Mathematics
Grade 1 · US Curriculum Standards
Grade 1 Maths builds real fluency with addition and subtraction within 20, using strategies like counting on and making ten rather than rote memorization alone. Place value work covers understanding two-digit numbers as tens and ones, which underpins everything that follows.
Students also compare and order objects by length, tell time to the hour and half hour, and work with simple shapes: recognising, naming and starting to understand their attributes. Note: exact pacing varies by state and district; this reflects a typical Grade 1 sequence.
