Coded Hundred Square

Stage: 2 Challenge Level: Challenge Level:1
We had a good number of suggestions as how to do tackle this challenge.

Adam, Anna, Rebecca and Chloe from Denmead Junior School sent the following:

When I was doing the coded word challenge I thought it was really hard but I had some numbers 1, 2 and 3 then those signs kept repeating. So when I saw the diamond which represented  1 and the shape also fitted in with it as well and  there were two diamonds that represented 11 and that also fitted in and so on. When I had those it was a case of fitting different symbols onto the grid but you had to use the single digits first. Like 1, 2, 3, 4, 5, 6, 7, 8 and 9 then you start your two digits.

I knew that the square went from 1 to 100. That meant there was a number that had 3 digits (100). I worked out that all of the numbers on the first row only had one digit so I started from the first row and worked my way on.

The way I worked it out was easy I just forgot about the numbers and the code and I just fitted the shapes in the way that they would go, and at the end I worked out the code and the numbers were right.

I was able to do this because I managed to find shapes that I could connect to each other. Also I worked out that it started with the single shapes to the double shapes and then the triplet   shapes. SO IT WAS EASY !!!! I was able to do it because I used the learning values such as independence, resilience  and collaboration. You should try it, it really makes you think and keep on going till you're finished and you will be proud.

Thank you Chloe for those useful words and now from George, Luca and Luc from The Hall Middle School:

The way that I worked it out was I was going to look at the patterns but then realised that I did not need to. Instead I made sure that in any direction at least once there was the same symbol in any direction. After that I went all the way through and it worked out. Also and then you have to begin in the top left corner, were 1 would begin and end in top left hand corner where ten would be, that is how I did it.

First I found the piece that had three digits, that was a hundred then I looked at what was on the left of a hundred it was square so then I knew that square was nine and then I just looked what was before 99 and so on until I had done it.

To first look for 1 which would have to be a single symbol on the top of one of the pieces then to see another single digit that fits in the space between the first and second piece.  When you know number one you have to find one with two different digits then there is one that fits and then you know all the numbers it is easy to find out.

We worked on this in pairs then we came together at the end to discuss how we had worked it out.  Then we took what we had said and put it together with a picture of our solution. We then saved this as a powerpoint which we have attached here.ppt .

Thank you all for these contributions.  Well done - keep sending in your ideas.
