## Reflection: Adjustments to Practice Comparing Fractions on a Numberline - Section 2: Common Mistake when showing fractions on a numberline.

Prior to Common Core, it was my practice to introduce fractions without any number line. The number line makes it so much easier to connect understanding of equivalent fractions as well as a great model to explain numerators and denominators. I can now ask a student to prove how 6/8 is related to 3/4 using a model. They can prove that the the whole is cut into eighths, we have six of them, and that is the same thing as when the whole is cut into fourths and we have three of them. The concept of fractions becomes meaningful because the student has the power to prove their understanding.
