# 3rd Grade Math Practice - Common Core Math Tests

## Free Test Online

According to the CCSS, third grade students should focus on four critical areas:
a) developing understanding of multiplication and division within 100,
b) developing understanding of fractions,
c) developing understanding of area and of rectangular arrays,
d) describing and analyzing two-dimensional shapes.

The following mathematics practice quizzes are designed to test the knowledge of third grade students. 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.

Teachers are welcome to use the mathematics worksheets of this website.

Third Grade Operations and Algebraic Thinking
3.OA: Students need to represent and solve problems involving multiplication and division, to understand properties of multiplication and the relationship between multiplication and division, to multiply and divide within 100 and to solve problems involving the four operations and explain patterns in arithmetic.

Third Grade Number and Operations in Base Ten
3.NTB: Use place value understanding and properties of operations to perform multi-digit arithmetic.
