Break It Apart or Build It Up! Composing and Decomposing Fractions with the Same Denominator

In this lesson, students will dive into how fractions with the same denominator can be broken apart and put together again — kind of like puzzle pieces! Using models such as shaded shapes and number lines, they’ll see how unit fractions like 1/6 + 1/6 become 2/6, and how 3/8 can be split into 1/8 + 2/8. This hands-on exploration will help students develop a deeper understanding of fractions as parts of a whole and prepare them for future fraction operations in upper grades. It’s all about knowing how parts work together — and how math is a lot like building with blocks! TEKS 3.3(D) compose and decompose a fraction a/b with a numerator greater than zero and less than or equal to b as a sum of parts 1/b
