Transformation using grids

 The other day our Toki pounamu teacher came in and decided that we are going to be doing a project that contains one tool on Google Drive. We used a 5x5 grid and had to use the line button to make a replica of the little picture on the left. This is how mine turned out. I found it hard to get the right shape of the boxes. I enjoyed when something worked perfectly. Have you ever tried this? If yes how did it work out?
