The fourth grade Language Arts curriculum includes objectives that support students' development in the skills of reading, writing, and oral language. These skills are developed through direct instruction, modeling by teachers, and guided practice. Teachers plan a balance of learning experiences, which build upon oral language and include fiction, informational text, and use of language arts skills in other content areas.

Fourth grade Mathematics students use a sense of number to read, write, order, and compare numbers to millions; recognize and use commutative and associative properties of addition and multiplication; estimate, add, and subtract four-digit whole numbers, fractions with like denominators, and decimals to hundredths; and multiply and divide two- and three-digit numbers. They estimate and measure length, volume and capacity; find area and perimeter of regular and irregular polygons; classify geometric shapes and angles; model three-dimensional shapes; investigate transformational geometry; and locate points on a grid using ordered pairs. Fourth graders collect, display, and compare survey data; recognize terms to express central tendency; determine probability; and record ratios.

The fourth grade Science Program consists of grade level units that are composed of inquiry-based, hands-on science lessons.  Science Process Skills, embedded in the lessons, develop student's ability to think and perform like a scientist.  In addition to science trade books and these hands-on kits, FCPS offers the Windows on Science visual textbook videodisk program, the Fresh ScienceDVD supplemental visuals, and United Streaming video library.  Interactive technologies used by students in the elementary science program include Weatherbug Achieve, and Easy Sense Q5 Probeware.
