Accurate Measurements

Some of you know that we are enclosing our side porch and making it our sun room. I have wanted this for year. As I watch the porch become transformed, I am amazed at how many learning opportunities there are in construction. I have watched the men measure wood and drywall over the past few weeks. They use many different tools as well. It is amazing how all these little things get put together and make something new. I also notice how these guys all work together.

Measuring has to be very precise or the walls and ceiling would not come out level. When the inspector came by to inspect before the drywall could be installed, he was quite impressed at the workmanship. Our contractor is very conscientious and goes further than he needs to sometimes.

When the roof was being put on, the men ran out of shingles. Then someone realized that the man in charge of measuring messed up and was short materials so the guys had to return another day to finish when the materials were delivered. Since we were given a price at the start, the company lost money on this job because of the measurement error.

I think it is important for students to see the relevance in learning new skills. These examples are just a few real life situations that involve measurement. The more that students are able to relate what they are learning to a situation where they might learn the new skills, the more they will understand and retain this new skill.

Do you use real life examples when teaching measurement? If so, what are some of the ways you make this learning relevant to students? Please share.

The Measurement Adventure

Let me start with the bottom line: We need to teach our students measurement! Yes, the metric system would be easier but right now, we don’t use the metric system so don’t ignore what we do use. Teach it! No, don’t just teach it. Teach it and have students apply their knowledge and use it. I remember teaching a unit of it and that was it. Then we never looked at measurement again. Like a foreign language, if you don’t use it, you lose it. Please, I beg you, teach it and have students use it every day.

Okay, now to explain my desperate plea. The other day I bought chains to hang my hanging plants from hooks in my porch. I found white plastic chains that were 61 cents per foot. I needed six chains and each chain needed to be 18 inches. Simple, right? Wrong! The young man that came to help me looked at me blankly when I said 18 inches. He looked at the measurement tape on the floor and said, “Hmmm, it doesn’t have 18 inches here.” I finally had to tell him that it was a foot and a half and showed him where it was on the tape. There was 17 links in the first chain and I suggested that we could count the links for the other chains so they could be the same size. He insisted that it was easier for him to measure it so away he went “measuring.” The next chain was 15 links and I told him that it wouldn’t work. So, then he decided that he better count the links. Okay, now we finally have six chains that were 17 links each. He could not figure out how to determine the price for the total. I had to tell him that the 6 chains equaled 9 feet in length and all he had to do was multiply 9 feet by 61 cents. He was very impressed with my skills! (Skills? I thought it was basic math!)

I really believe that you can incorporate math word problems in any subject area that you teach. Use them as bonuses on quizzes or tests. Use them as bell ringers when they arrive in your class. It involves reading so that should cover English and Language Arts. The math aspect is obvious. For Social Studies, use measurement with geography; figure out the heights of famous people in inches, figure out the cost of something bought during a certain time period, etc. For Science, use measurements with lab work. Measure a text book or some kind of object every day!

I worry about our students when they can’t figure out how to give change or to use simple measurements in life. They don’t realize these are important skills and I’m not sure that teachers are instilling this in their minds. All we seem to do is recognize it as a standard that we have to teach and then we teach the unit as if it is a stand-alone object. Once taught, we move on to something else and never look back. We need to show our students that basic skills are important and necessary in our everyday lives in order to be successful.

Here are some interesting sites I found to teach measurement:

Illuminations: Measurement
