until we figured out we could not solve it. This was actually a good exercise
for us to think about. I took a group of three people to figure it out. It was
easy to use the software. When you click on link it takes you to the first
puzzle and you try it.

this, I spent most of my time trying to figure out what to do on the site to try
to figure out the problems or issues discussed. Many of the problems I had
to read a few times to try to figure out what there was to do and how to solve
the problem. I was also interested to see what all the other links were on the
problems, as possible steps to help work through the problems.
I found the whole thing to be quit difficult. When I am on the internet
looking at a web like this, I feel like I am always looking for the fastest way
to find the answer to my question. When I am looking at something like Math, I
want to look at a book. I feel this site and problems had no introduction that
I have taken other internet classes at San Jose State and I found those class
sites to be much easier to use. Everything was a step by step process making it
very clear. This site should be completely redone and make is more
user-friendly. At least I found it to be this way for The Three Puzzles.
explained well enough to figure out the puzzles. The content of the software
talked about the history of the puzzle and how it was used.

another. This article does help me understand it better and the graph helps a
and i found it rather confusing. Once i just stopped and thought about it for a
few moments i relized i needed to get one cup of water in a glass. so as soon as
i figured out what steps to take to get that i solved the problem. the second
time i tried the problem i solved it rather quickly.
i think this a good tool to use because many things in math are confusing at
first, but if you stay with it, you can learn it, and it feels better once you

when things are drawnout, so I was able to remain focused on the problem. I
found the program simple to use without conflict. This problem took me about
5mins to solve, and after I found the answer; I forgot how to solve it haha. I
liked the problem because it would show my previous steps, so i could learn form
my mistakes. So, I could visually see what I was doing wrong. rather then
trying to remmeber it on paper.

frist and I really wanted to figue it out. The question seemed familar to a
question my professor asked us in class about "the igloos." I got stumped and
frustraded and just I gave up. I just couldn't slove it. I enjoyed the site
though it was intresting and very creative. I'd use this in the class as a fun
thing to do and think about.

It is hard for me to be able and see the puzzle i need someone to tell it to
me. im not sure if this would en hance any learning.
that is what i think about it.

puzzles and find it helpful for my brain. It helps the brain become more
active and more sensitive to some tricky problems. The link has the content of
some tricky puzzles that force people to think. Some might be hard, some might
be not, but if we don't think hard, we cannot solve it. It also give out
different ways of solving the problems so that one can take a look for
reference. The explanation of the relations between numbers are also very
interesting and helpful to read. We can also get a general rules for some
similar problems. The software is very easy to use. I was the first
time user and I didn't have any problems using it at all.

expand one's lateral thinking, as well as problem-related visualization, skills.
I spent well over an hour wrapping my brain around various problems, and the
explanations and analysis are top-notch. I think that first time users, as I was
one of them, will find it very easy to make use of the materials and they will
surely be pulled in by the many puzzles presented. I believe that this site
would be an excellent tool in helping students think "outside the box, " as it

nature. However, these puzzles are realistic enough to work on in a class or as
challenge. Pretty organized and user friendly!

couple of tries but in the end i did do it. I was able to make at least one of
the glasses contain 4 oz. of water. The material presented here can be used in
an elementary school type of environment to teach kids on how to do math using
computers and making math fun. The model here allows for teachers to use this
as a teaching tool for students who find math hard and boring. This will make
math fun for the kids. This was very easy to use. The instructions were very
simple and thorough so that any one would be able to understand it. Even me, who
is so bad with instructions:)

of three glass cups. I was confused, at first, about the whole point of the game
because I have Math issues. However, after getting totally frusterated and
loosing paitiece (after about 15 minutes) I looked at the answer and it made
complete sense. I then enjoyed going back and doing it knowing that it could be
solved and that I could actually do it. Thanks for the brain exercise. It was

navigate within the software and keeps the user wanting to try again and keep at
it to solve the problem. The water puzzle reminded me of a scotch and water
puzzle our teacher presented to us in class - so I tried it out. Although I was
unsuccessful after trying three times, curiousity got the best of me and I
viewed how another had solved it. It poses to the user a very significant
problem solving technique - if at first you are unsuccessful, try it again with
a different approach or a different technique. I spent about an hour on this
was unsuccessful at it. This puzzle does accurately present concepts and models
that are educationally significant because it helps show the users in trying to
come up with different models to try and slove the puzzle. By using this puzzle
in the classroom it will allow for a lot of critical thinking by the students.
The use of this software is very user friendly and the directions given are
very simple and can be understood by anybody.

L. J. by a fountain and they had to undo a bomb. They had to measure 4 units
of water and they had a 3 and 5 unit container . The "3 glass problem" was
pretty much the same situation and since I forgot how they did it in the movie
after trying the problem for a little bit I was able to get the answer. I found
this site to be very interactive as well as educational and i would recommend it
to those who like math problems or just want their head teased with for a while
I think this sight is educationally signifigant because of it's content.
Possible solutions are given and each step is given and explained in great
detail. Because of this I think this sight is a great teaching tool and a great
educational tool. This sight was set up a little weird but was not hard to
figure out for sure. First timers should have no problem on this sight.

Not only could I not solve it, but I couldn't make sense of it. I found this
game pushing me to try over and over again, challanging me to solve it. I think
it would be interesting to see someone who knew what they were doing to solve
it and explain what they did to solve it. This game does present concepts that
are educationally significant, and I think by finding out how to solve this
would challange students to think critically. There was not a problem using the
materials and software.
Jason Belligan (Student)
interactive game it could be used as a in class project. Its challenging and you
have to try different combonations and keep track of what you did. I found it
very easy to use and try and try again. I finnaly did cheat and got the answer ,
and found the actual sequence of numbers fairlly simple.

PUZZLES,LOOKED OVER THE INSTRUCTIONS AND STEPS. I TRIED THE VERY FIRST PUZZLE
AND GOT A HEADACHE I USED THE TRIAL AND ERROR APPROACH BUT I GOT NO WHERE SOO I GAVE UP THEN
STARTED TO WRITE NOTES AND LOOK OVER THE STEPS AGAIN.I NEVER DID COMPLETE THE
PUZZLE BUT I DID STUDY THE SOLUTION FOR A WHILE. THIS MATERIAL DOES ACCURATLY
PRESENT CONCEPTS AND MODELS. IT GAVE GOOD INSTRUCTIONS THAT WERE PRETTY EASY AND
EASY TO UNDERSTAND. THEY GAVE NUMEROUS MODELS TO TRY,DEFINITIONS AND SOLUTIONS.
I THINK THIS WOULD BE A FUN EXERCISE FOR A MATH CLASS, IT WILL CHALLENGE
EVERYONES BRAIN TO THE FULLEST. I THINK TOGETHER AS A CLASS IF SOLVED IT WILL
ENHANCE EVERYONES BRAIN FOR A HOT MINUTE! AS A FIRST TIME USER I FOUND IT VERY
EASY TO USE. THE SOFTWARE IS VERY SPOKEN FOR...

Merlot website, but instead I stumbled on the three glass puzzle at
(http://www.cut-the-knot.com/water2.html) which was very interesting since I
have been experiencing similar, but not so difficult puzzles to solve in my
current Math class. I liked the logic and reasoning that led to a possible
solution. I think more puzzles like this will be very helpful to stimulate a
student?s mind and inspire effective reasoning.
I never could. First when the problem drove me crazy, I was going to give up on
it, but then I asked one of my sisters to solve it, it challenged me to keep
going with the game. However, neither of us could solve, but at least we tried.
This puzzle is a very interesting game for your brain, because it makes your
brain work and think--even if u don't want to think. I'm not used to these
games, but I found it very challenging, especially when you play it with someone
else, and especially if that one is your sister or your brother, cause you want
to prove that you are smarter than him or her.
This puzzle was entertaining and challenging more than teaching, and a good
exercise for your brain.

problem I did enjoy trying. Everything was explained clearly and the graphs
were great but I just could not figure it out. At first I was just guessing and
hoping I could solvbe it that way but I was wrong. While opening up the
different pages to the problem I came across the step by step solution to the
problem which I thought was pretty cool. Overall i think this is a pretty cool
site if your in the mood to let your brain do a little exercise.

minutes at the local Kinko's. I tried to solve the puzzle by trial and error. I
could not solve this puzzle by any means. This sort of problem, sort of reminded
me about the Igloo question, you asked towards the begining of the semester,
with the diffrent type variations. As a first time user, the software was very

problem. I spent a good fifteen minutes figuring out the problem. I also tried
some other activities and they really make you think. This type of math is great
for teaching problem solving for everyday life. The material is pretty easy to
use and fun. Anyone can benefit from using this site.

creativity. I spent about 20-30 minutes reading through the site and trying out the different puzzles.
The theories seem interesting and the problems are challenging and would seem to be good material to present to students.
And the instructions seem basic enough to comprehend. A good site.

trying to solve it by trial and error. No luck. I very quickly noticed that I
was going in circles. My second attempt was a better approach. I wrote down
all the possible variations of 8 and my list was rather long. As I was making
my list, I noticed why my trial and error approach led me in circles. I tried
to use another approach by trying to minimize my list which would utilize
certain combinations. Still no luck in solvivng the puzzle. I eventually
solved the puzzle but I was not sure on how I was able to accomplish it. After
I solved it, I looked at the answer and it made the puzzle much easier to
understand. When I first looked at the puzzle, it appeared that it was going to
be fairly easy to solve. I very quickly found out that it was easier said that
done. The three glass puzzle consumed by mind as I attempted to solve it. (My
original work was done on Friday 921 at around 10pm but I was unable to save my
As a first time user, the software material was fairly easy to use.

less complicated for the students to learn the different solution methods. The
instructions were easy to follow and the quality of work was powerful.
