INTRODUCTION TO MY BLOG

Hello everyone and welcome to "Measurement & else"!

I am excited to establish this blog, because it is the second blog that I write about mathematics and I enjoyed writing the last one. This blog will be focused on : measurement. Sometimes, mathematics can be boring, but it will not my purpose. Mesurement has got interesting facts, curiosities that some of us do not know and the most important: we can measure almost everything that sorround us and thanks to that, we can interpret the reality in order to deal with issues that we can find in our society and environment.

The main objective of this blog is to present the measurement from a interesting point of view and also, from a didactic one. There will be several analysis of articles and resources than can be used in Primary Education classes. The mathematics and measurement are fun and it will be reflected in this blog so I invite you to share your opinion in it!

I hope you enjoy reading my entries!

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...

COUNTRIES´ SIZE

We have spent our entire lives looking at the wrong map: the Mercator projection ,which is the most frequently one used on the world maps. It enormously distorts the size of the countries or territories closest to the poles (essentially, those that are in the northern hemisphere) and, in comparison with it, it minimizes those that are closed to Ecuador, especially, South America and Africa. That explains why we have been mistakenly thinking that Greenland is similar in size to Africa, when in fact it is fifteen times smaller! [ Mercator projection of the world ] Moreover, a new projection to measure the countries was used at the beginning of the eighties in order to solve Mercator projection´s problematic: Gall–Peters projection . However, it was a terrible idea because it incurred a series of topographical errors. [ The Gall–Peters projection of the world map ] This distorting effect is inevitable due to the Earth is a sphere and not a...

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 mo...
