The focus is for students to explore, discover, and use the multiplication of fractions algorithm. Students draw upon their prior learning of algorithms for whole number operations and addition and subtraction of fractions as well as their conceptual understanding of fractions to gain an understanding of the multiplication of fractions algorithm and its efficiency for solving problems. Addition and subtraction of fractions with like and unlike denominators. Concept of a mixed number equal to a fraction, consistent use of visual models (fraction strip, number line, area model) and equations to solve word problems. Solve real-world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem Why are models important to help solve fraction problems?
