Comparing Numbers

Comparing numbers is a fundamental concept in mathematics. When comparing numbers, we determine the relationship between two or more numbers. The common comparison symbols used include:

To compare two numbers, we look at their values and use the appropriate comparison symbol to show how they relate to each other. For example:

If we have the numbers 5 and 8, we can say that 5 is less than 8, which we can write as 5 < 8.

Comparing numbers also involves understanding the place value of digits in a number. This helps us determine the magnitude of each digit and compare them accordingly.

When comparing larger numbers, it's essential to compare the digits in each place value position, starting from the leftmost digit.

For example, when comparing 356 and 245, we compare the hundreds place first. Since 3 is greater than 2, we know that 356 is greater than 245.

Using these comparison skills, we can order numbers from least to greatest or greatest to least, and solve various mathematical problems involving comparisons of quantities.

Number and Operations (NCTM)

Compute fluently and make reasonable estimates.

Develop fluency in adding, subtracting, multiplying, and dividing whole numbers.

Select appropriate methods and tools for computing with whole numbers from among mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tools.

Algebra (NCTM)

Use mathematical models to represent and understand quantitative relationships.

Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.

Connections to the Grade 3 Focal Points (NCTM)

Number and Operations: Building on their work in grade 2, students extend their understanding of place value to numbers up to 10,000 in various contexts. Students also apply this understanding to the task of representing numbers in different equivalent forms (e.g., expanded notation). They develop their understanding of numbers by building their facility with mental computation (addition and subtraction in special cases, such as 2,500 + 6,000 and 9,000 - 5,000), by using computational estimation, and by performing paper-and-pencil computations.
