Emily was willing to be my "tester" and she completed the Mastering the World of Measuring with the Master Rule book. Here is what she says...
I am in 6th grade and I did this book. It is very short. I think there should be more problems and exercises to do in it. I also think there should be more explanation. For example, had I not already known how to measure, I would not have known how to complete the problems in this book. With more explanation, I would recommend it.
I agree with Emily. The rulers are terrific and I'm sure we will use them for a long time. The poster I will use again to help 7 year old, Ellen master measuring. However, the workbook seemed lacking in explanation and in depth.
