  • 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

  • add and subtract multi-digit numbers accurately and efficiently

  • 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
