Grade 1 Math - California standards

Grade One

"Grade-one students begin to develop the concept of place value by viewing 10 ones as a unit called a ten. This basic but essential idea is the underpinning of the base-ten number system. In kindergarten, students learned to count in order, count to find out “how many,” and to add and subtract with small sets of numbers in different kinds of situations. They also developed fluency with addition and subtraction within 5. They saw teen numbers as composed of 10 ones and more ones. Additionally, kindergarten students identified and described geometric shapes and created and composed shapes (adapted from Charles A. Dana Center 2012).

Critical Areas of Instruction In grade one, instructional time should focus on four critical areas: (1) developing understanding of addition, subtraction, and strategies for addition and subtraction within 20; (2) developing understanding of whole-number relationships and place value, including grouping in tens and ones; (3) developing understanding of linear measurement and measuring lengths as iterating length units; and (4) reasoning about attributes of and composing and decomposing geometric shapes (National Governors Association Center for Best Practices, Council of Chief State School Officers [NGA/CCSSO] 2010h). Students also work toward fluency in addition and subtraction with whole numbers within 10."
