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 4, instructional time should focus on three critical areas:
- Developing understanding and fluency with multi-digit
multiplication, and developing understanding of dividing to find
quotients involving multi-digit dividends
- Developing an understanding of fraction equivalence, addition and
subtractions of fractions with like denominators, and multiplication of
fractions by whole numbers
- Understanding that geometric figures can be analyzed and classified
based on their properties, such as having parallel sides, perpendicular
sides, particular angle measures and symmetry
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 fourth grade level, visit the CPS Math Dept. website.
