Third Grade Math

The 2011 Massachusetts Curriculum Framework for Mathematics provides the primary foundation for mathematics instruction in grades at the Kennedy-Longfellow School. This framework builds on the Common Core State Standards for Mathematics and clearly defines and communicates what is expected of students at each grade level in terms of their mathematical understandings.

Investigations in Number, Data, and Space is the primary resource that is used for mathematics instruction. These materials are closely aligned to the new mathematical content. In addition to Investigations, teachers use additional instructional materials to ensure that students have many opportunities to achieve expected mathematics understanding.

In Grade 3, instructional time should focus on four critical areas

  • Developing Understanding of multiplication and division and strategies for multiplication and division within 100
  • Developing understanding of fractions, especially unit fractions (fractions with numerators of 1)
  • Developing understanding of the structure of rectangular arrays and of area
  • Describing and analyzing two-dimensional shapes

The Standards for Mathematical Practice describe varieties of expertise that all students of mathematics should develop from grades JK through 12. For more specific information on learning expectations for students at the third grade level, visit the CPS Math Dept. website.
