Manipulatives are physical objects that help learners understand abstract concepts through hands-on experience. Common examples include blocks, counters, and geometric shapes. They are often used in educational settings, particularly in subjects like mathematics and science, to enhance comprehension and retention. These tools allow students to explore and experiment, making learning more interactive and engaging. By manipulating these objects, learners can visualize relationships and solve problems, which can lead to a deeper understanding of the material. Overall, manipulatives serve as valuable resources in both classrooms and at home.
