Fourth Grade

Fourth grade students solve multi-step word problems using the four operations, including problems in which remainders must be interpreted. Students gain familiarity with factors and multiples and determine if a number is prime composite. Children also generate a number or shape pattern that follows a given rule and identify features of the pattern.

Grade 4 students read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form and compare two multi-digit numbers based on the meaning of the digits in each place. Fourth graders use place value understanding to perform multi-digit arithmetic on whole numbers including addition and subtraction using the standard algorithm, multiplication of a four-digit number by a one-digit number and two two-digit numbers, and division with up to four-digit dividends and one-digit divisors. Students also recognize that in our place value system, a digit in any place represents 10 times as much as it represents in the place to its right.

Fourth graders recognize and generate equivalent fractions, including fractions greater than one while also comparing two fractions with different numerators and different denominators using various strategies. Work also includes adding and subtracting mixed numbers with like denominators by replacing each mixed number with an equivalent fraction. Students apply and extend previous understandings of multiplication to multiply a fraction by a whole number. Children work with decimal notation for fractions and compare decimal fractions.

Grade 4 students solve problems involving measurement and conversion of measurements including customary and metric units. Students also apply the area and perimeter formula for rectangles in real-world and mathematical problems. Children understand concepts of angles and measure/sketch angles using a protractor.

Fourth graders draw points, lines, line segments, rays, angles, and perpendicular and parallel lines while identifying these in two-dimensional figures. Students classify two-dimensional figures based on attributes and recognize lines of symmetry within shapes.
