In 4th grade math, we 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
