Grade 4 Common Core math standards

Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7.

Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations.

Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number is prime or composite.

Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself.

Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits.

Use place value understanding to round multi-digit whole numbers to any place.

Fluently add and subtract multi-digit whole numbers using the standard algorithm.

Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.

Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors.

Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models.

Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators.

Understand a fraction a/b with a > 1 as a sum of fractions 1/b; add and subtract fractions with like denominators.

Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

Use decimal notation for fractions with denominators 10 or 100.

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money.

Apply the area and perimeter formulas for rectangles in real world and mathematical problems.

Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Recognize a line of symmetry for a two-dimensional figure. Identify line-symmetric figures and draw lines of symmetry.
