# Common Core Math: Grade 1

In first grade, students build fluency in adding and subtracting with numbers up to 20, including addition of three whole numbers. Students solve for unknown values in addition and subtraction equations and, based on place value understanding, add and subtract with multiples of 10. Students also describe shapes based on their defining attributes and compose and partition shapes. Students learn to tell time, represent data and measure lengths in various units.
