In mathematics, "less than" is a comparison between two numbers, where one number is smaller than the other. The symbol used to represent "less than" is <, and it is read as "is less than" or "is smaller than". For example, 5 < 8 means "5 is less than 8".

To understand the concept of "less than", it's important to remember the following key points:

**Symbol:**The symbol for "less than" is <. It is always placed with the pointed side towards the smaller number. For example, 3 < 7.**Comparing Numbers:**When comparing two numbers, if the number on the left is smaller than the number on the right, then the statement is true. For example, 4 < 9 is a true statement.**Number Line:**The concept of "less than" can be visualized on a number line. Numbers to the left are smaller than numbers to the right. For example, 2 is less than 5 because 2 is to the left of 5 on the number line.

It's important to practice identifying and writing "less than" statements and using the < symbol correctly when comparing numbers.

Remember, when comparing numbers, if the number on the left is smaller than the number on the right, it is represented using the < symbol as in the following examples:

- 3 < 7 (3 is less than 7)
- 12 < 20 (12 is less than 20)
- 2 < 5 (2 is less than 5)

Understanding the concept of "less than" is essential for solving mathematical problems and equations.

Practice comparing numbers and using the "less than" symbol to reinforce your understanding of this concept.

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
