Finding equivalent fractions
Equivalent fractions name the same amount with different-sized equal parts. Multiplying or dividing numerator and denominator by the same nonzero factor preserves the value.
The difference between area and perimeter
Perimeter measures the distance around a shape. Area measures how much surface it covers. For a rectangle, perimeter is 2 × (length + width) and area is length × width.

4th Grade math extends students’ skills to multi-digit multiplication and long division, operations with fractions, and an introduction to decimals. Students also develop geometric reasoning through work with angles, lines, and symmetry, preparing them for the transition to more abstract mathematics.
Key 4th Grade Math Skills
- Multiplying multi-digit numbers (up to 4 digits × 1 digit)
- Long division with remainders
- Adding and subtracting fractions with like denominators
- Understanding decimal notation for tenths and hundredths
- Measuring and classifying angles as acute, right, or obtuse
- Identifying parallel lines, perpendicular lines, and types of triangles
4th Grade applies 3rd Grade multiplication fluency and fraction basics to more complex multi-digit calculations and introduces the decimal number system.
The fraction and decimal foundations from 4th Grade lead directly into 5th Grade operations with fractions and decimals, including multiplication and division.
