"My year 10 class think that the puzzle is quite clever because it fools you into a quick answer, but then you start see the puzzle in a bit more depth and more rectangles appear.

We think the answer is 26, but are not 100% sure.

"We go to the highfield school and are in Year 8, we think that the answer was 26. At first it was difficult becuase we couldn't see the angles in the rectangles, but once we double checked we realised what the answer was."

"I was workin with a Year 5 class and they managed to find 26 as well. I am very suprised I though there were only 17 myself but then I looked closely and then I thought to see if my class could figure out how many they could but the thing is it took them nearly the whole hour lesson to figure it out!"

"26 is the answer I did it with my teacher and my class. My teacher's name is Miss Alexander. First we thought it was 5 or 6 or 9 but then we did it properly by drawing a few extra lines and we finished at 26 then we scrolled down and the answer was 26."

"To begin with I was really struggling to keep track of what I had counted and what I hadn't. I read the comments about 26 rectangles and couldn't find them. After a good 15 minutes I found a way that I could keep track and found 26. I think the people who found 27 must have counted something twice (as I also did at one point when I counted 28!)"

"I have done this with 5 different classes and my 9x2 wouldn't give up until we finally found how to get more than 14!"

Miss Davey 9x2, St Andrews High

"We also got 26 so I think the person who got 27 must have counted one twice. We found it hard at first and couldn't work out how there was so many there because at first we only counted 12 and then we kept going and managed to find 26."
