The dimensional learning material is -

Dimensional learning materials refer to educational resources that have physical depth and provide a tangible or three-dimensional representation of concepts.

Key Points 

• Model: Models are three-dimensional representations of objects, concepts, or systems. They provide a tangible and visual way for learners to understand complex ideas.
• Chart: Charts can be considered two-dimensional or three-dimensional, depending on the type. Two-dimensional charts (like graphs) provide visual representations of data, while three-dimensional charts (like pie charts) add depth to the visual presentation.
• Object: Objects, in the context of learning materials, can be three-dimensional items that students can observe, handle, and explore. Objects are particularly useful in hands-on and experiential learning.

So, all of the above is the correct answer.
