Today the children inquired into measuring a bit further. They were presented with question: “How wide is the classroom?” The only constraint they had was that they COULD NOT use any standard measurement tools. As firs, some thought this task was “hard” and “impossible” however, once they began to “think outside of the box” the children began exploring and measuring! They discovered MANY ways to measure the classroom: with hands, feet, fingers, leg length, blocks, pencils, erasers, chairs, connecting links and other learning tools. When we came together afterwards, the board was an explosion of answers to the question posed at the beginning. Some used their knowledge and experience earlier in the week and the question was open-ended and therefore that is why there are so many answers. However, in this case we realized that the width of the classroom was same for everyone who was measuring it and therefore they should have all gotten the same answer.. but they DIDN’T. This was when they realized the reason was because they had all used different tools to measure with.
I then posed the next question: “Why do we have standard units of measurement that are world-wide?” After some discussion and visual examples the children came to the understanding that having standard measuring tools will allow consistency no matter who was measuring or where they were. We will continue to dive deeper into the different measurement tools that we use and begin to explore measuring with some of them as we continue moving forward in this unit of study.
Here is a fun, catchy song that will get you using some measurement vocabulary!
