Adding and Subtracting Fractions

Miss Nelson teaches lesson 7.3 from the Florida Go Math book, focusing on adding fractions using models. The lesson revisits concepts from previous lessons, emphasizing the ease of adding fractions with the same denominator. A problem involving adding 1/8 and 5/8 of a loaf of bread is used to demonstrate the process. The lesson includes visual aids like models and fraction strips to illustrate the addition. Miss Nelson also briefly mentions how subtraction would work similarly if the denominators are the same. The lesson concludes with a reminder for students to complete their workbook page and a note on contacting her with questions.
