According to Jean Piaget's theory

• exposure to linear equation, techniques of solving
  it and pair of linear equations are assimilation

• introduction of linear equation and learning techniques of solving it are assimilation, and extending the concept to pair of linear equations may raise problem of accommodation 

• introduction of linear equation and learning techniques of solving it are assimilation, and extending the concept to pair of linear equations may raise problem of accommodation

• introduction of pair of linear equations and
  techniques of solving it are assimilation and connecting it to basics of linear equation is accommodation

Class VI students were given the following layout of a house

The students were asked to find out the

A. perimeter and area of each room

B. total perimeter and total area of the
house.

The above activity can be used by teacher as
formative assessment task because

• the students will find the task interesting and
  will not disturb each other

• it will remove the phobia of Maths examination

• it will be easy for teacher to engage all the students for 40 min period

• the students' responses will help teacher to diagnose their understanding regarding finding dimensions, calculations, knowledge of formulae for perimeter and area etc.

Student's ability to apply the concept of square roots in real life situation can be assessed through the following problem.

• Find the smallest number that may be subtracted from 5607 to get a perfect square

• 2025 plants are to be planted in a garden in such a way that each row contains as many plants as the number of rows. Find the number of rows and number of plants in each row

• Find the smallest square number that is divisible by each of the numbers 4, 9 and 10

• Calculate the square root of 25600
