What if we had a different number system?

As a small group we were set the task to create our own number system. We had already looked into different ways and symbols used to represent numbers (Egyptians, Roman numerals, Ancient Indian numerals, the Munduruku tribe and many more). After taking inspiration from all of these different number systems we had decided to create one that had links to mathematics in another way. Below we can see our small chart which explains the original number in one column, the symbol in the next column, the name of the value in the next column and finally the pronunciation in the last column.

This activity was very interesting to complete and to see how well we could develop our own system without it being too difficult. Once we started we found that it was going to be very hard to drift away from our normal base 10 system and our recognisable numbers. However, after giving it another relationship to maths then this allowed for us not to get too mixed up.

We could have continued this up to 10 or 12 however, if we keep it a 6 based system it would have a different method. For example once I had reached hexiy (6) I would go back to the start adding Oyo to the start of each number; Oyo-oyo (7), Oyo-veya (8) and so on. Once reaching Oyo-hexiy (12) you then would change the Oyo to a Veya; Veya-oyo (13), Veya-veya (14) etc. This method would continue all of the way up, working through each number (1-6) until we got to Hexiy-hexiy (42). What would happen here is that a new column would open up what could effectively mimic the hundreds column: Oyo-noy-oyo (43), Oyo-noy-veya (44).

Without going into too much depth the way in which these numbers work would be through columns. The first column on the right acting as a units column then every time we reach a six the next column to the left increase by 1 while the ‘units’ column always goes back to 1. Then when we reach six within that column the next column increases by 1 while the previous column resets to 0. To work out how much a number is worth you calculate the columns through multiplying and addition. The columns below show the values and methods for calculating the value.

The way in which we work this out is to constantly increase the unit’s column and then reset to 1. Each time this happens we increase the following column by 1. To work out the total value of these first two columns we multiply the second column value by 6 and then we add this onto the unit’s value, which gives us our total value of the number. We then take this further and when the second column reaches the value of 6 it resets to 0 and we increase the third column by 1. By this point to work out the total value you would multiply the third column value by 42 to get one value. Then multiply the second column value by 6 and then add the unit’s value with the two values already calculated from the second and third columns to give us our overall value. This has been shown briefly in the last column of our table

Although this may be quite complicated, and I must admit a calculator was needed to try and help with some of the calculations, I am very pleased that I have managed to devise a number system that I can explain how it works (although quite complicated).

Also this could be used in the classroom setting; we could get the children to try and make up their own, although this example is very complicated, number systems. You could have the children drawing their symbols out, creating different names or using physical objects to represent their number system. The process of discussing, planning, designing and then possibly making their number system.

My Escher Based Design Process

As part of our task from our second lecture on this course, we had to explore the idea of shape and tessellation or look into creating an Escher based piece of art. I decided I would attempt the Escher based task, where you start with a shape that tessellates and you take bits/sections and move them to a different side of the shape to create an animal which then tessellates itself. I will show you step by step how I went about creating my final piece.

Firstly I chose to base my design around the hexagon. picture 1Then what you do is you begin to, in a sense, ‘nibble’ away sections of the hexagon that will be used to move later on to create the animal. In the picture below we can see the hexagon being cut up into five different sections, four of which are blue. The reason why they are blue is to show that these are the pieces that are being removed from the hexagon.picture 2After removing the four pieces, we are left with an irregular hexagon. That looks a like the picture number 1. I then started to move the four removed pieces around to see where they would fit and what animal they would make, until I decided on the set up of picture number 2. Showing the finalised joining of the shapes in number 3.picture 3Below you can see the new shape against the original hexagon (dashed line hexagon in red) that I started with.picture 4Here we can see the original shape and we can identify the areas that have been moved around. As a result of using a hexagon this means that our new shape will tessellate to create a very interesting picture but first we need to add the details of what animal this is.picture 5I decided to go for the design of a fox’s face and then tessellated this to create the final tessellation design below.picture 6

We can then go onto to change the colours of the foxes to make it relate more to Escher’s design. But the reason why this foxes face tessellates is because of the starting shape, a hexagon, has 360° when the shapes are joined together. This is shown in the picture below with the hexagons.picture 7

Below you can now see my finished design of the tessellation of a hexagon inspired by Escher.

I do feel this would be quite possible to take into the primary classroom and these steps are quite simple. It can be completed with real materials or, as I have done, with the computer and this will help enhance the children’s computing skills.
