How would you incorporate the use of standard units, the use of tools to measure, the importance of precision and accuracy, estimation and the use of manipulatives and other visual aides to a group of third graders to make them understand the common concept behind measurements regardless of what is being measured? Why is it important that I explain to them so that they will understand that measurement has some common skills and tools necessary?
Why is it important that I explain to them so that they will understand that measurement has some common skills and tools necessary.
It is important to explain this to students so that they realize that things need to be standardized to avoid problems. To emphasize this, you can have students measure objects in the room with their hands (or with their shoes) and record the answers. They will most likely come up with different numbers of hands, either because hands are different sizes, or because they don't measure using the same beginning and end points. You can also give them an example situation: suppose you said you wanted a bed that was 8 feet long by 4 feet wide. Have a student measure out 8 feet by 4 ...
