According to the National Curriculum Framework (NCF 2005), the main objective of mathematics teaching at the primary level is to develop the capacity of 'mathematization' in children. In this context, combined with the provisions of Section 29 of the RTE Act 2009, which of the following teaching methods is most relevant to achieve this objective?

Both the National Curriculum Framework (NCF 2005) and the Right of Children to Free and Compulsory Education Act (RTE Act 2009) are based on the constructivist approach. According to NCF 2005, the purpose of mathematics teaching is to teach children to think mathematically, rather than just rote-learning formulas and mechanical calculations. For this, concrete experiences and daily life contexts should be used.
