4th Grade Math 

4th Grade - Math

By the end of the school year, students are expected to:

  • Read and write numbers less than 1,000,000.
  • Add, subtract, and multiply with multi-digit numbers (ex: 485 + 622 = ? OR 30 x 542 = ?).
  • Multiply 2- or 3-digit numbers by 1-digit numbers.
  • Divide with single digit divisors (ex: 4821 divided by 7), with and without remainders.
  • Know place value of each digit in a multi-digit number to the tenths and hundredths places (ex: 45.93).
  • Use and write decimals and commas in the appropriate places.
  • Memorize the divisionfacts/tables through 10.
  • Show, know, and compare rational numbers (fractions 3/4 and mixed numbers 3 3/4).
  • Add and subtract numbers with like denominators.
  • Add and subtract decimals; tell what happens and record.
  • Round rational numbers to the nearest whole number; tell why.
  • Estimate solutions to problems.
  • Match decimals and fractions (tenths and hundredths) to each other using models and pictures.
  • Solve multi-step problems using one of several strategies: make a chart / graph, look for patterns, make a simpler problem, use logic, work backwards, and break into parts.
  • Know points, lines, and angles (acute, right, obtuse).
  • Know properties of plane figures (sides, angles, vertices).
  • Know properties of polyhedra (solid figures that have faces, edges, and vertices).
  • Know plane figures after turns, flips, and slides.
  • Estimate and measure length, capacity and mass. Use inches, miles, centimeters, kilometers, milliliters, cups, pints, kilograms, and tons.
  • Find perimeter and area of rectangles and triangles using grids.
  • Make and interpret stem-and-leaf plots and line plots.
  • Know and use bar, picture, and circle graphs.
  • Conduct a survey or experiment. Collect and organize data (including data collected over time) on a chart or graph.
  • Tell about information from charts, tables, tallies, and graphs.
  • Use range, median, and mode to describe a set of data.
  • Make guesses based on probability. Experiment with objects which give random outcomes such as: coins, number cubes, and spinners.
  • Make and solve word problems.
  • Use the calculator and computer as appropriate.
