In Mrs.Poole's science class we are learning how to measure using meters, centimeters, inches, millimeters,etc. We are also learning how to find the lenght,height,and width of a box. This has helped me so much, because some of the things that we learned how to measure i didn't even know what they were! Mrs.Poole also told us that the end of the ruler isn't always a zero. She told us that we have t look carefully and find the zero ourselfs, because if we use the end of the ruler as a zero our measurments can be wrong. I was so happy she told us this, because in the future it can help me a lot, so i won't get the wrong measurments.
