Fractions - Add Mixed Numbers - Presentation

The lesson on adding mixed numbers is a continuation of learning about fractions, aimed at enhancing students' understanding of how to combine these numbers. A mixed number is a combination of a whole number and a fraction, and students are prompted to provide three examples to solidify their comprehension. The lesson includes a series of activities, starting with adding mixed numbers by first combining the whole numbers and then the fractions. For example, students learn to add 4 and 5/8 to 1 and 2/16 by taking a step-by-step approach: adding the whole numbers to get 5, then adding the fractions 5/8 and 2/16 to obtain 5 and 12/16, which simplifies to 5 and 3/4.

Further exercises encourage students to convert mixed numbers into improper fractions before adding them together. This method involves combining the whole numbers and then the fractions, such as adding 2 and 6/10 to 3 and 4/5 by converting them to 26/10 and 19/5, respectively, and then summing them up to get a result of 64/10, which simplifies to 6 and 4/10. The lesson also includes reasoning activities where students explore different methods of adding mixed numbers, such as Zach and Leanna's combined milk consumption, and are asked to determine the most efficient method. Independent work tasks challenge students to choose their preferred method for solving calculations and to fill in missing numbers in given problems, reinforcing their understanding of mixed numbers and their addition.
