Fractions - Improper to mixed numbers - Presentation

In the educational presentation on converting improper fractions to mixed numbers, students are introduced to the fundamental concepts of what constitutes an improper fraction and a mixed number. They are encouraged to discuss these concepts and provide examples to solidify their understanding. The lesson includes practical activities where students learn to convert improper fractions to mixed numbers using visual aids such as cubes and bar models. For instance, the character Kate demonstrates how to transform the fraction 15/4 into a mixed number by grouping cubes into sets of 4, with 3 left over, illustrating that 15/4 is the same as 3 and 3/4. Students are then prompted to apply Kate's method to other fractions such as 13/2, 13/3, 13/4, and 13/5, converting them into their respective mixed numbers.

Further exercises involve another character, Malachi, who uses bar models to convert the fraction 30/7 into a mixed number. Students are tasked with using this visual strategy to work on additional examples like 20/9, 38/8, 38/7, and 70/6. The presentation also includes reasoning challenges where students must identify and correct mistakes in fraction conversions, such as spotting that 28/5 is incorrectly written as 5 and 2/5 instead of the correct mixed number. In the independent work section, students use bar models to assist in the conversion process and are asked to identify errors and justify their reasoning. The discussion prompts at the end of the presentation encourage students to think about the relationship between the parts of a whole and the effect of changing the denominator while keeping the numerator constant, as well as what happens when the numerator is a multiple of the denominator.
