1. Start with the Basics: What is a Fraction?
* Parts of a Whole: Begin with the fundamental concept: a fraction represents a part of a whole. Use visual aids like circles, rectangles, or even pizza slices divided into equal parts. Show them that a fraction is written as a numerator (top number) over a denominator (bottom number), separated by a line. The denominator tells you how many equal parts the whole is divided into, and the numerator tells you how many of those parts you have. For example, 3/4 means 3 out of 4 equal parts.
* Real-World Examples: Relate fractions to their everyday experiences. "If you eat 2 slices of a pizza cut into 8 slices, you ate 2/8 of the pizza." Use other examples like sharing candy, measuring ingredients for baking, or telling time (15 minutes is 1/4 of an hour).
2. Different Types of Fractions:
* Proper Fractions: The numerator is smaller than the denominator (e.g., 2/5, 1/3). These represent less than a whole.
* Improper Fractions: The numerator is greater than or equal to the denominator (e.g., 5/3, 8/8). These represent one whole or more than one whole.
* Mixed Numbers: A combination of a whole number and a proper fraction (e.g., 1 2/3). This represents a whole plus a part of a whole. Show how to convert between improper fractions and mixed numbers (and vice-versa).
3. Visual Models are Key:
* Fraction Bars/Circles: Use pre-made fraction bars or draw circles divided into equal sections to visually represent fractions. This helps students see the relationship between the numerator and denominator.
* Number Lines: Show fractions on a number line, placing them between whole numbers. This helps visualize the order and relative size of fractions.
* Area Models: Use rectangles divided into grids to represent fractions. This is particularly helpful for understanding multiplication and division of fractions.
4. Equivalent Fractions:
* Simplifying Fractions: Explain that equivalent fractions represent the same amount but are written differently. Use visuals to show how simplifying a fraction (reducing it to its lowest terms) doesn't change its value (e.g., 2/4 = 1/2). Emphasize dividing both the numerator and denominator by their greatest common factor.
* Finding Equivalent Fractions: Show how to create equivalent fractions by multiplying or dividing both the numerator and denominator by the same number (other than zero).
5. Comparing and Ordering Fractions:
* Common Denominators: Teach students to compare fractions by finding a common denominator (a common multiple of the denominators). Once they have a common denominator, they can easily compare the numerators.
* Visual Comparison: Use visuals like fraction bars or number lines to help compare fractions.
6. Operations with Fractions:
* Addition and Subtraction: Start with fractions with common denominators. Then, move to fractions with unlike denominators, emphasizing the need to find a common denominator first.
* Multiplication and Division: This is generally introduced later in sixth grade and may require more advanced techniques. Visual models and real-world examples are very helpful here.
7. Practice, Practice, Practice:
Use a variety of exercises, including:
* Word problems: This helps apply fraction concepts to real-world situations.
* Games: Make learning fun with fraction-based games and activities.
* Worksheets: Provide plenty of practice problems to reinforce understanding.
Remember to be patient and encourage students to ask questions. Building a strong foundation in fractions is crucial for future math success.
