As your son or daughter approaches the later years of elementary school, she or he moves away from learning basic math toward a deeper understanding of academics. Here are some samples of fourth-grade mathematics standards, useful questions to ask your son or daughter’s teacher, and strategies for helping him or her learn at home.

### Operations and Algebraic Thinking

1. Use an understanding of place value to compare multi-digit numbers that use decimals to find greater, lesser and equal numbers.
2. Divide four-digit numbers by one-digit numbers; work with remainders.
1583 ÷ 3= 527.6666 = 527.67
3. Solve word problems by adding, subtracting, multiplying and dividing whole numbers, including measurements and remainders.

### Number and Operations in Base Ten

1. Add and subtract within 1,000,000 quickly and accurately.
248,961 + 360,842 = 609,803

### Number and Operations: Fractions

1. Multiply, add and subtract fractions with common denominators.
2. Solve problems that require fractions to be broken down to common denominators.

### Measurements and Data

1. Do word problems involving measurement of time, weight and distance.

### Geometry

1. Identify various types of lines, including right angles, parallel and segments; use these classifications to categorize two-dimensional shapes like trapezoids and rectangles.
2. Solve problems that involve area and perimeter.
Q: Find the perimeter of the hexagon.

A: In a hexagon, all sides are the same length, so each side is 8 inches long. The perimeter of the hexagon is 6 sides × 8 in. = 48 in.
