Maths - Measurement

 For a couple of days we have been learning measurements. The teacher gave us a sheet of paper with different things we have to measure. We had to measure how tall we were without our shoes on, the length of our right foot without our shoe on, our arm span, the circumference of our wrist, the circumference of our neck, and our popliteal length, which is the length from the back of our knee to the back of our heel. 

I am 148.9 cm tall, my foot is 26.3 cm long, my arm span is 150.5 cm, my wrist is 15 cm, my neck is 29 cm, and my popliteal length is 39 cm. We had partners that we would measure these things for, and my partner was Camille. Here is a link to her blog. We had metre rulers and measuring tape to use, and we had chalk to mark where. 

I enjoyed finding out my measurements because I never knew them before. I found it tricky to measure Camille, because I had to reach across her to reach the next place. Luckily, we got another person to hold the measuring tape/ruler. Nobody in my class knew what a popliteal length was, until we did this activity. The teacher said that we could do it independently, without her because she had testing to do, and it took us two days.

We went out to the concrete when we had to measure our foot, and marked with the chalk on it. For the popliteal length, we sat on a chair while the other person measured with the measuring tape. For the arm span, we went up to a wall and spread our arms out, so we looked like a lowercase t. Then the other person would get the measuring tape and put the start to the tip of one middle finger, then roll it out until it reached the tip of the other. For the height, we stood against the wall again and had the other person use the metre ruler to measure it. 

Have you ever measured these things on you? Did you know what a popliteal length was before reading this? Tell me in the comments! Here is a picture of my sheet!
