Anisha and Amit study in Class VIL Anisha told Amit that if the marks in Mathematics of each student in the class are increased by 5, the average would go up by 5. She further says that it is true for all numbers. Amit does not agree and Anisha proves it by taking the case n, instead of 5. Anisha is using

• deductive logic

• common sense

• estimation

• inductive logic

Using technology based games involving factorization of numbers or formation of new shapes by joining 2D shapes, etc

• enhances students' ability to understand the concepts better as they are able to explore, observe and infer at their own pace

• helps teacher to assess students' performance in Mathematics

• helps teacher to manage students in Mathematics laboratory

• enhances students' numeracy skills and computational skills
