ACTIVITY – Percent Problems
Objective:
To use a 10 x 10 grid as a model for solving various types of per cent problems.
Materials Required:
Sketch pens, squared paper, colour pencils, geometry box, etc.
Procedure:
1. To represent the actual per cent.
1. Draw a 10 x 10 grid on a squared paper as shown in Fig.
In the figure, one whole square represents 100 per cent and one small square represents 1 per cent.
2. In the bottom of the big square, shade 30 small squares horizontally as shown in fig to depict 30 %
2. In the bottom of the big square, shade 30 small squares horizontally as shown in fig to depict 30 %
II. To represent the less than 1 %.
To show less than 1 per cent mark as shown in Fig. 3.
III. To represent more than 100%.
1. Make two grids of 10 x 10 each on squared papers.
2. To represent 150%, we shade one grid in full and the other 5 rows ( or 50 small squares) as shown in Fig.
100% + 50 % = 150%
