PLAYFUL ACTIVITIES TO WORK THE CONCEPT OF MEASUREMENT IN CLASS

Sometimes, mathematics can be difficult to understand by students due to the complexity of it, and also this problematic can be presented in the concept of measurement. For this reason, I would like to expose three useful and playful activities that can deal with this situation.

1. MEASUREMENT LADDER
The concept of metric unit change is a problematic issue for students because they are not aware of what the process itself supposed. As a result of this, they are not able to identify when a multiplication or division is involved in the metric unit change process. MEASUREMENT LADDER is a playful technique that is oriented to solve this problematic issue. The simile of a ladder will be used to explain the jump from one unit of length (mass or capacity) to another. So, when we would go up from meters to kilometers we have to divide by 10 for each step we climb and on the other hand, when we would go down, we carry out the same process but multiplying by 10.

To make even more playful and significant the process of learning, the ladder of the school could be decorated; consequently students could feel engaged and motivated to the activity.

2. MEASURING THE WORLD
Once students have clarify the concept of changing of measure, we could use the ICTs to still working this concept. The teacher would select certain important buildings or monuments such as the Pyramid Giza, The Chinese Great Wall or The Empire State Building from New York. Students would have to search in Internet what are the height of theses buildings or monuments and the teacher would demand them to change into a specific measurement unit. 
Finally, the teacher could select some important buildings from the city where students live and to request them to compare how many times is bigger the specific building that they have just searched in Internet than the building from their city. This simple activity could make closer the concept of changing measurement unit and, at the same time, to show them that this concept has a real finallity in their world.

3. UNCONVENTIONAL MEASURING INSTRUMENTS
This last activity is oriented to youngest students, it is to say, students from the first cicle of Primary Education. The teacher would propose them different objects from the classroom and students have to measure them just using unconventional measuring instruments such as their fingers, giving steps, using school materials or whatever students would like to use.Once, students would find out how many times are the object of the class using the optional measuring instrument, the teacher would introduce them the concept of meter, decimeter and so on. Students would be able to undertand that every object can be measure and it is formed by specific measuring units.

EVOLUTION OF THE ELECTORAL STATISTICS IN SPAIN

We are facing an electoral panorama very uncertain and, in turn, numerous since there are several elections around the corner. To help voters get an idea about what the Spanish population thinks, surveys are carried out and graphic representations are formed from that. In order words,  statistics are essential in the electoral process . For instance, this is the last survey that collect the voting intenention and what political party will be voted by Spanish citizens. Statistics has been always present in the election period and to illustrate this reality, I would like to expose some significant data collected from the election results from the last decades. The average participation has been 73.79% since 1977, while the year 1982 was the year with the highest participation ( 79.97% ) and on the contrary it was the year 2016 when fewer Spanish people went to vote at the the polls on election day ( 66.48% ) Moreover, the PSOE was the political party with more seats...

THE EFFECT OF MEASUREMENT IN MUSIC

Does it exist any connection between mathematics and music?, and if so, how does it affect us? As surreal as it turns out, the relationship exists. To understand it, we have to go back to ancient Greece, specifically Pythagoras. He was who discovered the importance of numbers in music and the relationship between this discipline and mathematics. The word mathematics comes from the Greek word μάθημα, which means "knowledge". Pythagoras and his followers divided this science into four areas: arithmetic, geometry, astronomy and MUSIC . For this reason, we could affirm that the Pythagorean philosophers were the ones who laid the foundations of our current music. Nowadays, mathematics has to do even more with acoustics than with composition and the use of mathematics in composition is historically limited to the simplest operations of measuring and counting. As a result of that, we could affirm that we feel emotions and feelings through songs because of...

DRAWING CONCLUSIONS

As it was explained in the previous entry, "CURIOUS NBA STATISTICS",  statistics is "a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data". The application of statistical procedures dates back to the year 3050 before Christ , when a register of population and wealth was carried out in Egypt in order to prepare the construction of the pyramids. Later, Egyptians, Greeks and Romans also carried out some censuses with tributary, social and military purposes, and much later, in the sixteenth century, statistical inventories were published in Germany, Italy and France. Although initially the statistics arises from the elaboration of censuses, its application is currently extended to numerous fields, such as agriculture, biology, politics, psychology, education and so on. However, there are many people who for lack of critical sense of a statistical nature are very easily impressed by surpris...
