## Reflection: Quizzes Quiz 2 Showing Our Understanding of Decimals - Section 2: Quiz Time!

In this Educreations video, I show you some writing samples of the explanation comparing .8 and .08. For the most part, students really did a good job using the words tenths and hundredths to compare the differences between them. They also explained that 8 tenths was larger. I saw some varied understanding of comparison of fractions and bringing the tenths out to hundredths to compare and therefore making some foolish errors. i.e # 3 .79 to .9, the students didn't bring the .9 out to .90 to compare, yet did it on # 5 when comparing .06 and .6. Therefore many said that .79 was larger than .90. That may have to do with understanding the "how" and not the "why" we would bring out the tenth to the hundredth place. They are looking at it as a process when the numbers are the same: . 6 . 06. It's just a hunch, and based on what I understand about my student's minds and that as we transition to CCSS, I have to continually battle the " I just want to know how to do it," frame of mind.
