When comparing two numbers, "less than" is used to describe the relationship between the numbers. If one number is smaller than another, we use the "<" symbol to represent "less than". For example, 5 < 8 means "5 is less than 8."

- 3 < 7 (3 is less than 7)
- 12 < 20 (12 is less than 20)
- 25 < 30 (25 is less than 30)

To understand the concept of "less than," it's important to practice comparing numbers using the "<" symbol. Here are a few tips to keep in mind:

- When comparing two numbers, identify the smaller number.
- Write the smaller number on the left side of the "<" symbol and the larger number on the right side.
- Remember that the "<" symbol points to the smaller number, indicating that it is less than the larger number.

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

Connections to the Grade 5 Focal Points (NCTM)

Number and Operations: Building on their work in grade 4, students extend their understanding of place value to numbers through millions and millionths in various contexts. They apply what they know about multiplication of whole numbers to larger numbers. Students also explore contexts that they can describe with negative numbers (e.g., situations of owing money or measuring elevations above and below sea level).
