Place value word problems

Learning Objectives Identify the value of a digit in a number up to 1,000. Read and write numbers in standard, expanded, and word form to solve problems. Compare two numbers up to 1,000 using the symbols >, <, and =. Solve one-step and two-step word problems involving place value comparisons. Use place value understanding to explain the relationship between digits in a number. Apply place value concepts to solve real-world scenarios.

Expanded Form Rule For a 3-digit number `abc`: `(a * 100) + (b * 10) + (c * 1)` Use this to break a number apart to see the value of each digit. For example, 528 is (5 * 100) + (2 * 10) + (8 * 1), which equals 500 + 20 + 8. Comparison Rule Start comparing digits from the largest place value (left to right). To compare 675 and 682, first look at the hundreds place (both are 6). Then, look at the tens place (7 and 8). Since 8 is greater than 7, we know that 682 > 675. Value of a Digit Rule Value = Digit * Place's Value To find the value of a digit, multiply the digit by its place value (1, 10, 100, etc.). The value of the 4 in 491 is 4 * 100, which is 400.
