This in turn encourages students to reflect on the new knowledge and skills that they have acquired to cross check their findings, ensuring that they have completely understood to process to achieving the correct answer (Reys, Lindquist, Lambdin & Smith, 2009). Students who explore mathematical equations using meaningful situations will develop ways to adapt and apply formulas to enable them to practically apply it to real life. Teaching mathematics needs to focuses on engaging students using real mathematical problem. (Booker, Bond, Sparrow & Swan, 2004). Promoting number sense in the classroom using authentic activities can be done using hands on activities such as: 1. Creating a scenario and asking students to act it, for example buying and selling.
