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.
