Quick ways to measure area by counting rows and columns? Calculating area is one of the most important concepts in mathematics. It is one of those concepts that has its usage even in the daily life. For example, when you go out to purchase a carpet for your living room, you will have to provide the shopkeeper the area of your living room. Moreover, if you to buy a table cover, you need to know the total area of the table for a cover that will perfectly fit. Kids might find it difficult to calculate area of the two-dimensional shapes. There are a few techniques which make area calculation very easy for kids and one technique is by counting the rows and columns. The technique is useful for regular polygons including squares and rectangles. You can start by dividing the shape into square centimeters, millimeters, or meters, as per the given the dimensions. When you successfully divide your shape into rows and columns, all you have to do is count the rows and write it down. Then you have to count the number of columns. To get the final answer you just multiply the number of rows with the columns to get the final answer. These worksheets help students learn to measure total area by finding the sum of all the area of a figure.
