Are you looking for a lesson to teach students how to add with rational numbers? This lesson covers adding both positive and negative fractions (fractions, mixed numbers, and improper fractions), decimals, and percents from the development stage to independent practice following the I do, We do, You do instructional model. This lesson is part of the Texas TEKS: 7.3A and 7.3B. The introduction includes the TEKS as well as learning objectives and student goal setting for the lesson.
