• The material includes printed materials, graphs, charts apart realia, models and real objects. Realia materials and models are real material brought into the classroom.

Definition of 2 Dimensional (2D) materials

• 2D materials refer to materials with length and width. This material is flat and is not designed to provide depth. Some examples of 2D material including photographs, prints and posters which have only two characteristic, the width and length.

Among 2D material are:1. Printed Material - include textbooks, reference

books, worksheets and printed materials provided by the teacher.

2. Chart – organizational chart is more often used to classify or show category about specific materials, events, and species of animals or plants according to the group. Students can clearly see if the teacher shows the classification chart.

• Map refers to an abstract representation of a real place where people live. Map consists of visual symbols, lines, and colors

Definition of 3 Dimensional (3D) materials

Refers to a material that has length, width and height. 3D objects comprises of various shapes like cuboid, cone, cube, sphere, models, dioramas, and realia.

Realia

• Realia material is real material. Examples of realia are like leaves and small animals that can be found in the environment.a) Natural Realia

• This is a living material, such as earthworms, grasshoppers, and so on,
