During the Upper primary stage, slowly children must be given the opportunity to deal with abstract concepts. This is the stage at which algebra needs to be introduced. It should be introduced by connecting it to real-life situations and through its use in solving various life problems. In algebra, the emphasis has now been given to equations by broadening the base to include ideas such as mathematical sentences, replacement set and solution set.

Keeping the above stated higher objectives of mathematics education in view, the NCF 2005 have spelt out the vision for school mathematics : 

• Children use abstractions to perceive relationships, to see structures, to reason about things, to argue the truth or falsity of statements. Logical thinking is a great gift of mathematics can offer us, inculcation, such habits of thought and communication in children is a principal goal of teaching mathematics.
• Children understand the basic structure of mathematics: Arithmetic, algebra, geometry and trigonometry, the basic content areas of school mathematics, all offer a methodology for abstraction, structuration and generalization. 
• Children pose and solve meaningful problems: In school, mathematics is the domain which formally addresses problem-solving as a skill.
• Teachers engage every child in the class with the conviction that everyone can learn mathematics. 

Thus from above-mentioned points, it is clear that Generalisation is an important aspect of algebra in Class VI.
