WK 7 Puzzles

I decided that I would do my puzzles with my younger sister. I found two puzzles and she agreed to do the exercise with me. I have organized this post as follows, 

-My sisters worksheet

-My worksheet

- The solution

After we were done solving the triangles I asked my sister to walk me through how she solved it. First she counted all the little green and yellow triangles as they stood on their own (not combing triangles). After that she combined the triangles to make a bigger triangle. From there she went to the center where there is a smaller square formed and she counted those. She ended up with a final number of 28.

I did pretty much the same thing. I first counted all the triangles separately. Then I cut the whole square in half to get two really big triangles. After that I combined two of the little triangles together to get a slightly bigger triangle.  Next I went and divided up the smaller square in the middle. I too got 28 triangles. 

After that we consulted the solution. We both got 28 triangles but we both got it wrong. There were more triangles than we found. We found the triangles we needed too but instead of counting all four we only counted two. My sister and I needed to take it a step further to get all the necessary triangles.

The next puzzle my sister and I embarked on was this one above. We needed to located the star symbol among the shapes without interrupting the outline. This one was really hard for the both of us.

The first thing my sister did was try and locate a pattern. She said she first looked at all the pink and blue triangles. She found some pink and blue triangles that were going the opposite direction of the other pink and blue triangles. She tried to make a connection with the triangles that were going the "right" way and the opposite way but she couldn't come up with the star. From there she moved on two the bigger green and yellow triangles and used the same strategy as before. She said like the pink and blue triangles she found half were going in the opposite directions as the others. She said she continued to look for the star but become stumped and couldn't find it. 

When I started this puzzle I too tried to locate a pattern. I was looking at the small triangles and the bigger triangles trying to see if I could come up with something. I then started to break in the given star symbol on the side of the page to smaller shapes to see if I broke it down it would maybe be easier to locate in the actual pattern. That did not lead me anywhere. The next strategy I used was turing the paper different orientations. In the directions it said it could be any size or orientation as along as the outline wasn't disrupted. I turned the page sideways and upside down to see if maybe that would help me isolate the star symbol. However all my strategies were taking me nowhere. I too become stumped and after some spent really trying to envision this star among the rest of the shapes. 

After some my sister and I decided to give in and see where the hidden star was. After we looked the solution we both had "a-ha" moment. I think this was the hardest puzzle, very challenging.
