In grade 4 math, your child will:

  • Understand factors and multiples, e.g., 1, 2, 4, 5, 10, and 20 are all factors of 20, and 20 is a multiple of each of those numbers

  • Understand that a prime number has only 2 factors—1 and itself, while a composite number has more than 2 factors

  • Multiply multi-digit numbers using strategies based on place value and properties of operations

  • Divide 2-digit numbers by 1-digit numbers using strategies based on place value and the relationship between multiplication and division

  • Read, write, and compare multi-digit numbers and round multi-digit numbers to any place

  • Add and subtract multi-digit numbers accurately and efficiently

  • Recognize and generate equivalent fractions

  • Compare two fractions with different numerators and denominators

  • Add and subtract fractions and mixed numbers with like denominators

  • Multiply a fraction by a whole number

  • Write fractions with denominators of 10 or 100 in decimal notation

  • Compare decimal numbers with digits to the hundredths place

  • Know the relative sizes of measurement units within one system of units, including metric length, metric mass, customary weight, metric volume, and time

  • Use formulas for area and perimeter of a rectangle to solve problems

  • Measure and sketch angles with a protractor

  • Classify 2-D shapes

  • Identify and draw lines of symmetry
