Transformation using grids

Today we found an accredited image on Explore and selected it to use on our page. We then put a 5x5 grid on it so we could copy the image and make it original. Mrs Minehan selected the first two images so we could understand the process, then we got to choose our own image. I found the first one was easy because I could use circles. The second one was also easy because it had no background I chose the image of the star because it looks fun and easy. Have you ever tried to transform an image using a grid? How did you find the process?
