This task asks students to use two different denominators to subtract fractions. The purpose of this is to help students realize that any common denominator will work, not just the least common denominator.
In this lesson, students will use nautical flags to apply their understanding of addition and subtraction of fractions with unlike denominators within context. This is remixable if you provide additional supports for the range of learners.
This task allows students to explore a situation involving the estimation, addition, and subtraction of fractions with unlike denominators. This is remixable by adding student work or you can upload a new resource also aligned to this standard.
