In education, realia (/ r iː ˈ eɪ l ɪ ə /) are objects from real life used in classroom instruction by educators to improve students' learning. [1] A teacher of a foreign language often employs realia to strengthen students' associations between words for common objects and the objects themselves. In many cases, these objects are part of ...
The units represent ones, rods represent tens, flats represent hundreds, and the cube represents thousands. Their relationship in size makes them a valuable part of the exploration in number concepts. Students are able to physically represent place value in the operations of addition, subtraction, multiplication, and division.
They can represent items, people, activities and/or events, and look or feel similar to what they refer to. [2] [3] [5] [6] For example, a cup can be used as three-dimensional tangible symbol to represent the action: "drink". [6] A photograph of a cup can be used as a two-dimensional tangible symbol to also represent the action: "drink".
The use of multiple representations supports and requires tasks that involve decision-making and other problem-solving skills. [2] [3] [4] The choice of which representation to use, the task of making representations given other representations, and the understanding of how changes in one representation affect others are examples of such mathematically sophisticated activities.
The Principles and Standards for School Mathematics was developed by the NCTM. The NCTM's stated intent was to improve mathematics education. The contents were based on surveys of existing curriculum materials, curricula and policies from many countries, educational research publications, and government agencies such as the U.S. National Science Foundation.

A mathematical object is an abstract concept arising in mathematics. [1] Typically, a mathematical object can be a value that can be assigned to a symbol, and therefore can be involved in formulas. Commonly encountered mathematical objects include numbers, expressions, shapes, functions, and sets.
3D model used for teaching geometry. Instructional materials, also known as teaching materials, learning materials, or teaching/learning materials (TLM), [1] are any collection of materials including animate and inanimate objects and human and non-human resources that a teacher may use in teaching and learning situations to help achieve desired learning objectives.
A learning object is "a collection of content items, practice items, and assessment items that are combined based on a single learning objective". [1] The term is credited to Wayne Hodgins, and dates from a working group in 1994 bearing the name. [2]
