This six-week course is designed to provide students with a thorough understanding of fractions, guiding them from basic concepts to practical applications in various contexts. The course introduces fractions by breaking down their components—numerators and denominators—through real-world examples and visual representations such as pie charts and number lines. Students will learn to identify proper, improper, and mixed fractions, and will practice simplifying them using the greatest common divisor.

In the following weeks, students will explore equivalent fractions, understanding how to create and visualize them. They’ll learn strategies for comparing and ordering fractions, both with the same and different denominators, allowing them to determine which fractions are greater or smaller.

The course also delves into operations with fractions, beginning with addition and subtraction. Students will tackle these operations with both like and unlike denominators, as well as work with mixed numbers. The course then moves on to multiplication and division, teaching students to directly multiply fractions and to divide them using reciprocal fractions. Mixed numbers will again be incorporated into these operations.

In the final week, students will apply their knowledge of fractions to solve real-world problems. They’ll explore how fractions convert to decimals and percentages and use them in geometric and algebraic contexts. Word problems based on practical situations like cooking, budgeting, and measurements will help reinforce the lessons. By the end of the course, students will not only be proficient in all fraction operations but also confident in applying them in everyday life.

The course concludes with a comprehensive review and a final exam, ensuring that students have mastered each concept. Optional projects, such as designing a recipe using fractional measurements, provide hands-on learning experiences to solidify their understanding.
