The denominator is the bottom number in a fraction. It represents the total number of equal parts into which the whole is divided. For example, in the fraction 3/4, the denominator is 4, which indicates that the whole is divided into 4 equal parts.

**Definition:**Learn that the denominator is the bottom number in a fraction and represents the total number of equal parts into which the whole is divided.**Representation:**Understand how to represent the denominator in a fraction and its significance in showing the number of equal parts in the whole.**Comparing Denominators:**Practice comparing fractions by comparing their denominators. The larger the denominator, the smaller the size of each part, and vice versa.**Equivalent Fractions:**Explore how equivalent fractions are created by multiplying or dividing both the numerator and the denominator by the same number.**Adding and Subtracting Fractions:**Practice adding and subtracting fractions with different denominators by finding a common denominator.**Multiplying and Dividing Fractions:**Learn how to multiply and divide fractions, where you multiply numerators and denominators, and invert and multiply for division.

Understanding the denominator is crucial for mastering fractions and their operations. Practice using fractions in various contexts to reinforce your understanding of denominators.

Subtracting Fractions

Number and Operations (NCTM)

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers.

Compute fluently and make reasonable estimates.

Use visual models, benchmarks, and equivalent forms to add and subtract commonly used fractions and decimals.

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 5 Focal Points (NCTM)

Algebra: Students use patterns, models, and relationships as contexts for writing and solving simple equations and inequalities. They create graphs of simple equations. They explore prime and composite numbers and discover concepts related to the addition and subtraction of fractions as they use factors and multiples, including applications of common factors and common multiples. They develop an understanding of the order of operations and use it for all operations.
