1) When I was doing the tangram at first it was to easy to cut up the pieces in the right spot and follow the directions but after that it was kind of confusing and frustrating putting the pieces all back together, because it was my first time doing the tangram and I did not have any idea how I can do it. After completing the tangram I felt relief.
2) The challenging part was when I tried to find the missing pieces. I had a hard time to connect the pieces all together and it was so much frustrating and it takes so much of my time to figure it out, but at the middle, I notice, if I put the same shape pieces all together it got more easy and less frustrating to complete the tangram.
