Maths - Measurement

 For the past few days, my class was learning to measure. Our teacher asked us gave us some  measurement tasks. There were 6 tasks and there were 6 stations. The tasks were: Measure how tall we were without our shoes on, the length of our right foot without our shoes on, our arm span, what is the circumference of our wrist and neck, and last but not least, what was our popliteal length. You may wonder, what is a popliteal length? Well, keep on reading and you'll find out!

For measuring our height, we had to use meter rulers. These rulers were all one meter. We first had to get a hard cover book, then a piece of chalk. We had to have a buddy so they could help. Our buddy had to put the book over our heads, then they slid the book down until it touched our heads. After that they put a mark next to the book with chalk. Then they used a meter ruler and put the top on the mark, then they marked the other end with chalk. This showed where 100 cm was on our bodies. Finally, they measured the rest of our heights with the meter ruler once more. My height was 152 cm!

For measuring our right foot, we went outside with our buddies out onto the concrete. We took our right shoe off and marked the big toe of our foot with chalk. After, we marked the heel of our foot. Then we used a normal ruler for both marks. My right foot length was 23.5 cm!

Next for measuring our arm span, we had to find a wall to lean on. After we found a wall, we leaned on it and our buddies used a measuring tape to measure our arm span. We had to measure from the tips of our right middle finger to our left middle finger. My arm span was 150.5 cm!

Then for measuring the circumference of our wrist, we had to use a tape measure. We wrapped the tape measure around our buddie's wrist, then answered to the nearest centimeter. The circumference of my wrist was 13 cm!

Last but not least, measuring our popliteal length! The answer you've been waiting for is here. What is a popliteal length? The popliteal length is the measurement from the underside of the right leg behind the knee when seated, to the floor, taken with shoes off! Us and our buddies just did that. My popliteal was 39 cm!
