To reinforce the students in understanding the concept of Decimal representation, Math Lab activity was conducted on 20th October, 2015 at Orchids The International School Koparkhairane, one of the best schools near Ghansoli, for Grade 4 students during the Math period. Students had to colour the worksheet with 10 x10 grids printed on it with crayons using different colours. The number of squares occupied by each colour was then counted. The fraction for each colour was written down and then expressed as decimals. The designs were then displayed on the bulletin board.
