Grade 4 math, age 9 to 10

Grade 4 students extend place value understanding through multi-digit numbers to 1,000,000, performing multi-digit addition, subtraction, and multi-step multiplication and division. They explore fraction equivalence, addition and subtraction of fractions and mixed numbers with like denominators, and decimal notation for tenths and hundredths. Geometry and measurement emphasize perimeter and area formulas, angle measurement, and geometric properties such as lines of symmetry.
