Manipulative materials

           Active learning methods place students at the center of the educational process. In the context of geometry, this means encouraging them to manipulate objects, explore, build, represent, and reflect. Engaging with geometric properties through hands-on activities allows students to internalize concepts more effectively by making abstract ideas concrete and accessible.

Using physical materials not only enhances spatial understanding, but also fosters deeper connections between shapes, relationships, and reasoning. As Zabala (2007) points out, meaningful learning is strengthened when students are given opportunities to manipulate, experiment, and apply content in contexts that are familiar and motivating.

This academic year I have done my second practicum, which focused on the topic of geometry and was oriented to the first grade of primary school. In this post, I will share some hands-on examples of how to explore these concepts in the classroom, as well as how this topic can be used to develop a variety of skills and competencies.

The first example of a manipulative resource is specifically designed to support the association and classification of geometric shapes. The main goal was for students to be able to independently group elements such as triangles, circles, and squares.

Another example is the geometric puzzle with which students classify and categorize elements according to their characteristics. This game of matching shapes and colors favors children's cognitive development by improving attention and stimulating visual-motor coordination and fine motor skills

The following activity proposal consists of a card game developed in pairs, allowing the students to work together and cooperatively with their partners, and to apply this learning independently. 

The dynamics of the game consisted in the distribution of four cards per pair, with representations of basic geometric figures (square, rectangle, rhombus and triangle). Each card contained the visual representation of a two-dimensional geometric figure and two sections to be completed that specified the number of sides and vertices that made it up. The students had to complete these sections on the same card according to the drawing provided. Once completed, each pair had to build the figures with wooden sticks and plasticine, thus consolidating the content worked on through a tangible experience. This transition from reproduction to creation helped students to consolidate their learning.
