In first grade, students typically learn about place value and how to read and write numbers in standard form. For example, the number 24 can be understood as 2 tens and 4 ones. The digit 2 is in the tens place, and the digit 4 is in the ones place. This can be written as 24 or as 20 + 4.

Students may also learn about expanded form, where a number is written as the sum of its place value. For example, the number 24 can be written in expanded form as 20 + 4.

It is also common for first grade students to learn about the value of digits in numbers. For example, in the number 42, the digit 4 is in the tens place and has a value of 40, while the digit 2 is in the ones place and has a value of 2.

It is important for students to understand place value as it helps them to understand the value of digits in numbers and to perform arithmetic operations such as addition and subtraction.

## Benefit

Learning about place value is an important foundation for understanding higher levels of math, including arithmetic and algebra. Understanding place value helps students to:

- Read and write numbers in standard form, expanded form, and word form.
- Compare and order numbers.
- Perform operations such as addition, subtraction, and multiplication.
- Understand the value of digits in numbers and how they contribute to the overall value of the number.

By learning about place value, first grade students will be better equipped to tackle more advanced math concepts in the future. It is a fundamental building block that will help students to develop a strong foundation in math.

Here are ten sample questions to help your first grade student practice place value:
