Abstract

Mathematics is one of the curricular fields of study at the Elementary School (SD) level. Due to the lack of students' understanding of this lesson, especially the material for mixed integer arithmetic operations in class VI of SD Negeri Neglasari, the compiler made the learning better. Classroom Action Research (PTK) was conducted at Neglasari Public Elementary School in the second semester of the 2022–2023 school year to improve learning in class VI, which consisted of 30 students., Student learning activities in the Mathematics subject matter of arithmetic operations on mixed integers with the application of manipulative materials row blocks in two learning cycles.
