Approaches to calculation - audition ExampleThe supplementation of mathematics learnt in school with their home based symbols can make kids get under ones skin a deeper and better comprehension of what is taught in class.In figure 3 Barney has used various symbols to beam his idea. He has used beans, flowerpots, the hand, arrows, numerical (10, 1, 2, 3, 6, 4 and 5) and garner (t, I, s). Barley strives to represent mathematical expressions using symbols. He states that 10 t 1 is p which means that 10 take away(predicate) 1 gives 9. In this instance he uses the letter t to represent the mathematical symbol of () which means minus. The letter p stands for 9 in an inverted form. The full-length representation is supposed to mean that 1 taken away from 10 gives 9 or in a mathematical symbol way its merely 10-1=9. He also states that 2 t is 1 to mean 1 taken away from 2 gives 1. He uses another form in the second instance involving arrows and a flowerpot with beans in it. The arrows acclivitous from the pot are symbols that represent the act of taking away a bean the pot and the way out of beans in the pots to the right of the arrow represents the number of beans that are left once the bean is takeaway from the pot. This whole representation stands for a quantity mathematical symbol of 2-1=1 and 8-1=7 expressed in Barneys own symbols. Code switching is evident here as he switches from using numerical and letters to drawings and arrows. He then switches to using numbers and arrows and is which represent the equal star sign in a standard mathematical representation. The arrows denote the minus or take away sign. Lastly he draws the hand with a numerical on it to denote that the number has been taken away from a set and is means the equals sign (Giangrasso & Shrimpton, 2013, pp112- 178). Barleys recordings give a pictorial representation to the mathematical expression and appeals to the eyes of the
