Students made mural using square sheets of paper

As not sure where you want us to post the answer, so I have made two posts; one directly to your blog and the other in mine.  Will clarify by tomorrow.


Ans to ~ How many sheets of square paper are needed to make this mural?  The Answer is 160 pieces of square paper.

First way of getting the answer:
by pasting the square paper horizontally and vertically.  Then count the number of paper used across and down and multiple the number.

Second way of getting the answer:
find out the area of the board, then find the area of the square paper (to find area we need to measure the length and breath and multiply it). The area of the board divide the area of the square will give tell us the number of square paper require.

To further extend the the task, we can ask children how many pieces of green, pink, yellow, blue and orange square paper are required to fill the mural and the number must be the same for all mentioned colours.
