This math unit begins with learning the basics of adding mixed fractions with different denominators without simplification, progressing to mastering the addition with one or two denominators changed. Students first focus on the mechanics of fraction addition, then move towards adding and subtracting fractions with varying complexities, including finding and adjusting to common denominators without initially simplifying the results. As the unit progresses, students learn to simplify their answers post-addition and subtraction, enhancing their skills in reducing fractions to their simplest form. Further into the unit, subtraction of mixed fractions is introduced, where students continue to work on problem setup and simplification. They also tackle more complex problems that involve finding missing values in addition and subtraction equations, illustrating a deepened understanding of fraction operations and the importance of denominator alignment. This sequence strengthens their ability to handle multiple aspects of fraction manipulation, culminating in a comprehensive grasp of adding and subtracting fractions with mixed numbers.more
