To write this post I wanted to know since when kilmeters (km) and kilograms (kg) were used and where the definition came from ! I learned a lot ! I tell you Blogging enlarges your general knowledge ! First I learned that both are "SI"s and is an abbreviation of " International System of Units". Kilograms and Kilometers were used already from 1791 onwards and today the whole world uses it except the USA. In the UK miles and pounds is in a form of transition, the elderly people still use miles, while the young generation learns km and kgs at school.
My son of course learned it too. Unfortunately he was the victim of a school teaching reform, which made everything more complicated. One day I realized that he didn't know what a km or a kg meant except the two letters k and m and k and g. To him one kg rice and one kg sugar were two different things, one was sugar and one was rice that the weight was the same was another thing. The school didn't use a visual teaching but only an "abstract" one.
I was horrified and angry ! I complained to the director but was told that yes before they showed children sugar and rice and weighed them on a balance so that they could see that a kg was the same weight for sugar and rice.
What did we do ? I took rice, sugar, flour and whatever I could find in my storage, and let him put it on a balance so that he realized that all of the products showed 1 kg !
It was the same with the kilometers ! Mr. G. put his son in the car and drove 1 km from our house to the bakery. Then two km from our house to another point he knew. So he learned that a km was a thing to measure the distance.
I probably wasn't the only parent who complained because the teaching reform was reformed again and today the children have a visual teaching again !
