Volume Test - Samples of Level 4 Answers



Hello Peanut Gallery!

I'm done marking your volume tests and should have them back to you on Monday.  To help you see how you can improve, I've decided to show you some samples of work that got Level 4 answers for each question.  This can help you improve for the next time.

We will chat further about this on Monday.

Take care!
Ms. Pike

Knowledge and Understanding

You can see in this question how the correct formula for volume was used V=(Area of the base)xH and then the measurements were substituted in for the different variables.  As well, in question #2 you can clearly see how the conversion from mm to cm was done so that all of the units were the same.  The problem can not be correctly solved if all units are not the same.

Thinking


The work is not only nicely organized in a chart like format, but there are labels for each column, the dimensions for each rectangular prism are clear, as is the area of the base and the volume for the entire figure.  Math vocabulary is used (dimensions, volume, area of base).  There is no confusion as to what the thinking process was.  Nothing that was asked for in the question was left out.

Communication
 
The biggest "downfall" for many of you in not achieving a Level 4 in this question was that you did not use correct math vocabulary!  The use of the word "dimensions" was one of the most important words that could have been used in this problem to help you explain how the volume was the same but the dimensions that were used were different but all resulted in multiplying to give the same volume.
 
 
 
 
Application
 
As you know from all of the discussions we have had about this category, what you need to do for an application question is apply your knowledge and understanding (and schema) to this type of question.  It really is a two part question:  part 1: The knowledge needed to solve the problem (in this case, the formula for Volume) and Part 2: Applying what you know from other areas of your life (schema) to help take the knowledge you have of volume and apply it to the context of this problem.
