Algebra is introduced in the middle classes. According to Piagets' theory of cognitive development, it is appropriate to introduce algebra at this stage as
the child is at sensorimotor stage and can understand with the help of lots of manipulatives
the child is at pre-operational stage and can understand abstract concepts
the child is at concrete-operational stage and he can understand and conceptualize concrete experiences by creating logical structure
the child is at formal operational stage and is fully mature to grasp the abstract concepts
Following is a problem from textbook of Class VI

Read the approaches used by the two teachers to teach solving oflinear equation, say 2x - 6 = 10
Teacher A | Teacher B |
Steps (a)Take 6 on other (b) Change the sign of 6 and add to 10 (c) Get 2x = 16 (d)Take 2 on the other side and divide (e) Get x = 8 |
Steps (i) Equation always mentain equality. So, same operation with same number can be performed on both sides to maintain equality (ii) HENCE, 2X - 6 + 6 = 10 + 6 = 2X = 16 (iii) |
It can be observed that
teacher A focuses on conceptual knowledge while teacher B focuses on procedural knowledge
teachers A and B focus on instrumental
understanding
teacher A emphasizes on instrumental understanding while teacher B emphasizes on
relational understanding
teacher A emphasizes on relational understanding while teacher B emphasizes on instrumental understanding
