basic concepts | My teacher journey

In a workshop, I took part in a business situation which demonstrated an application of Profound understanding of fundamental mathematics in the real world!

An overview of what was involved in this business simulation:

We had 5,000 Euros to spend for each quarter of the year
We had to choose a maximum of 5 items to sell for each quarter
We had to choose what quantity of items we wanted (quantity being a basic concept which is needed to have a profound understanding of fundamental mathematics according to Ma (2010, p.104))
We had to be careful and look at how much we were buying the item for to ensure we were not paying more for an item than it was being sold for such as the Christmas selection boxes in January.
We had to keep track of how many items were sold and whether they could be carried over into the next quota or whether it was a ‘write off’
We calculated how much we had spent by adding the prices together and subtracting what we had spent from the 5000 Euros or money we had to see what was left over. Therefore, through this process we were building upon each stage and adding to it over a period time which links to longitudinal coherence (Ma, 2010, p.104). Furthermore, we connected basic concepts together such as adding, subtracting, multiplying, percentages and decimals

We had to look at multiple perspectives to see what we were going to buy and sell however, we didn’t really look at multiple perspectives from a mathematical point as we continued to use the same methods of calculations throughout the session.

However, although we tried to be tackle by what we bought by guessing what items were more likely to be bought around a certain time of year, we could have looked ahead and seen that for January there was a sale price mark-up which mattered more. For example, beans only cost 25p to buy but they were being sold for 2.50 euro and 100% were sold. Therefore, there was a ten times mark up. Consequence, if I was to do this again i would pay more attention to the price per unit that we were buying it for and the seasonal price in order to make a bigger profit.

In the future, I would like to use this activity or at least one similar to further pupils understanding and application of fundamental mathematics in the real world or in the wider society. Therefore, they could connect and link various topics together for a meaningful purpose (Ma, 2010, p.104). It would be a fun and creative task or game for the children to do and could potentially due to the relevance of the task, it could give them an interest in business as a future career. However, in order to improve this activity I would like to further gain the children’s interest as well as emphasis the relevance by having the packaging of the actual items out on desks to further emphasise the relevance.

Can I really link everything back to basic mathematics? This is what I am keen to explore and learn about through the Discovering Mathematics module. In this blog post I am going to discuss how connecting mathematical errors made in other areas of maths can be linked back to basic, fundamental mathematical principles.

In the first workshop of discovering mathematics, we discussed how many things around us can be linked back to basic principles and concepts in mathematics. Some basic principles and concepts of maths are weight, quantity, addition, subtraction and division. It is interesting how there are some things that we have just accepted when we are taught mathematics. A word to describe this is, axiomatic. (English Oxford Living Dictionaries, no date). For example, one add one is two however, what is the number one? It is universally agreed that one is one. One is a number that represents or symbolises for example, one pen, a quantity of something. Quantity being a basic concept in maths.

However, the number one is something that I just seem to accept, one is one. It’s universally accepted. This can’t be the same for all things to do with maths. Pupils need to understand why things just are, why they are accepted

More complex maths or maths errors that children or even some adults might make can be linked back to fundamental basics. Ma (2010, pp.24-25) looks at errors in pupils’ long multiplication answers. Children when doing long multiplication where not lining up numbers into the correct positions. Teachers had different opinions as to why this was a problem. Some teachers said that it was because pupils just did not line the numbers up correctly whilst others argued that the the errors are because the pupils do not understand the reason or relevance of what they are doing in their algorithms. Therefore, an argument between algorithms being just a process that children need to memorise and the need to understand why they were doing something.

I agree with the latter argument, that the mistakes were due to a basic principle and concept not having been understood. This being, place value. For me personally, I know that when I was taught how to do long multiplication I was taught a process, a procedure that I had to memorise. I was not told why I was doing the procedure and some pupils may not have understood the basic principle that connects to the solution that is necessary in order to solve the maths question. The children in this example given by Ma, is that the pupils did not understand the value of the the numbers.

Therefore, since this mistake can be connected to a basic mathematical principle not being understood then maybe other mistakes can be too! This is why when teaching in the future, I should analyse the mistakes made by pupils since once basics are understood then they can be applied to other mathematical concepts and teach children to further their own understanding of fundamental mathematics by being able to work back to the basic concepts to see where they may have made an error.

In chapter 5, Ma (2010, p. 104) gives advice that I want to take on board in my teaching practice such as, making connections between the current topic or concept of maths to other concepts in maths, to show pupils more than one way to solve a problem so that they can take various approaches to solve a problem thereby, looking at things from multiple perspectives, to focus on the basic ideas and to build upon these foundations.

In conclusion, to aid my understanding of mathematics and the reason behind pupils errors, I will demonstrate the rationale behind the maths that pupils are doing and the connection that it has to other concepts so that it’s not just a memorised procedure that is accepted. Therefore, pupils can understand why they are doing what they are doing, the logic behind it and how it connects to fundamental mathematical concepts that they need to understand first. Pupils can therefore see how the maths that they are doing makes sense.

More than memorising!
