Students are expected to develop a deep understanding of addition, subtraction, and numerous strategies for addition and subtraction within 20.
The also will develop numerical understanding of whole number relationships and place value. Students will received many opportunities to begin measuring lengths as linear units. Composing and decomposing geometric shapes while reasoning about attributes are studied.
Students extend their understanding of the base-ten system. They receive numerous opportunities to learn a deep understanding of place value.
Students build on their foundation of number from first grade to develop fluency with addition and subtraction within 100 and solve problems within
1000. They continue to study measurement (time, length, and weight), geometry and problem solving. Problem solving strategies, including bar modeling, are studied, and students are introduced to multiplication.
Students develop a deep understanding of multiplication and division,including strategies and models for multiplication and division within 100. Students begin work with fractions. Two-dimensional shapes are described and analyzed, as well as area of shapes. Application of problem-solving strategies continues.
Students continue toward achieving mastery of mathematical computations of all whole numbers, and addition and subtraction of decimals and fractions.
More advanced word problems and problem-solving strategies are studied. The study of measurement includes conversion of units and representing and interpreting data. Geometry in fourth grade includes a study of the concepts of lines and angles.
The study of fractions and decimals is expanded to include multiplication and division. Students further their understanding of measurement with
conversion of units and volume. Concepts of three-dimensional shapes are also studies, as is graphing on coordinate planes. Hands on experiences provide a foundation for later algebraic studies. Application of problem solving.
