What Students Learn in 4th Grade
Fourth graders read, write, compare, add, subtract, multiply, and divide with very large whole numbers. They do more equations with fractions and decimals and learn about prime numbers (numbers that can only be divided by themselves and 1). They solve problems about factors (one of two or more numbers that can be multiplied) and multiples (a number that can be divided exactly by a smaller number) and explore geometry formulas for determining perimeter and area, and for measuring angles. Fourth graders figure out conversion problems, such as determining the number of minutes in an hour, or ounces in a pound. They not only read graphs, tables, and charts but should be able to create them from data they’ve collected.
