1st Grade Math Practice - Common Core Standards

Free Test Online

 




We have developed mathematics practice tests that illustrate the range of difficulty expected by the first grade common core state standards. We are not afiliated with the National Governors Association Center for Best Practices (NGA Center) or the Council of Chief State School Officers (CCSSO) which coordinate the CCSS initiative.
According to the CCSS, in first grade, students should focus on four areas:
a) developing understanding of addition, subtraction, and strategies for addition and subtraction within 20,
b) developing understanding of whole number relationships and place value, including grouping in tens and ones,
c) developing understanding of linear measurement and measuring lengths,
d) reasoning about attributes of, and composing and decomposing geometric shapes.

First Grade Operations and Algebraic Thinking
1.OA: Students need to add and subtract within 20, to represent and solve problems involving addition and subtraction, and to understand and to apply properties of operations.

First Grade Number and Operations in Base Ten
1.NTB: Extend the counting sequence, understand place value and use place value understanding and properties of operations to add and subtract.

First Grade Measurement and Data Practice
1.MD: The 1.MD CCS standards require first grade students to measure lengths indirectly and by iterating, to tell and write time and to represent and interpret data.

First Grade Common Core Geometry Practice
1.G: First grade students are expected to be able to reason with shapes and their attributes. They should distinguish between defining attributes, create composite shapes and partition circles and rectangles into two or four equal shares.
