In the
United States, children are usually enrolled at school at ages 8–9. In
mathematics, students are usually introduced to
multiplication and
division facts, place value to
thousands or
ten thousands, and
estimation. Depending on the elementary school, third-grade students may even work on
long division, such as dividing in double digits, hundreds, and thousands.
Decimals (to tenths only) are sometimes introduced. Students work on problem-solving skills working to explain their thinking in mathematical terms. In
science, third-grade students are usually taught basic
physics and
chemistry.
Weather and
climate are also sometimes taught. The concept of
atoms and
molecules is common, the states of
matter and
energy, along with basic chemical elements such as
oxygen,
hydrogen,
gold,
zinc, and
iron.
Nutrition is also sometimes taught in third grade, along with
chemistry. In
reading and
language arts, third-grade students usually begin working more on text comprehension by using informational articles or different genre books than
decoding strategies. Students also begin reading harder
chapter books. They read and distinguish between various book genres:
realistic fiction,
non-fiction,
poetry,
fantasy,
historical fiction,
science fiction and
folktales. Kids learn to read, vocabulary, and writing strategies such as finding main idea, finding theme, citing textual evidence, compare and contrast, nouns, verbs, context clues, writing narratives, writing research reports, writing explanatory essays, and writing persuasive and argumentative pieces. Grade 3 students learn how to work on projects on their own and with others. This may start as early as second grade and first grade as well.
Social skills,
empathy and
leadership are considered by some educators to be as important to develop as the academic skills of
reading,
writing and
arithmetic. Although more common in the past than today, many students begin writing in
cursive at this grade level. In some schools, cursive writing is taught in earlier grades, such as in second grade. == References ==
