Fourth-grade year, students add and subtract fractions, recognize equivalent and non-equivalent fractions, know the characteristics of lines and angles and feel comfortable analyzing, collecting, organizing and presenting data.
Your fourth grader will begin to branch out a bit in reading. He'll work on gaining a more sophisticated vocabulary, beginning to look at word roots, prefixes and suffixes to figure out unfamiliar words and to associate them with words he already knows.
Fourth-grade writing is closely interconnected with reading. If reading fables and folk tales, your child is likely to be writing his own stories with himself as the hero.
In science, students are ready to move on to looking at the scientific processes of classification of organisms, the arrangement of objects by properties and measuring events. Topics he might explore this year include the motion of objects, electricity and circuits, fossils, meteorology, and trait inheritance.
