Fraction Comparison Reflection

Knowing many different ways to compare fractions is good. I would think it would be rather difficult to compare fractions if you only knew one way to compare them. This is because there are different kinds of questions in math. Some methods tend to be more effective than others at times. When you know many strategies, you can get things done more efficiently and faster.
Here is and example of what I mean:

6/7 to 7/8; in these two fractions, you would probably want to use cross multiplication. If you only knew reasoning (benchmarks), this would be a problem for you.

Or, 13/18 and 4/12; reasoning (benchmarks) would be quickest and easiest way to compare this pair of fractions.

Do you know the saying "horses for courses", meaning that you should choose the horse that does best in the course that you are about to do (or the other way around where you choose the perfect course for you horse), well, it is kind of the same in math. It is important that you know many ways to compare fractions because you need the right tool for the right problem.

    Congratulations, you used examples in our learning, you told us why we should know many ways to compare fractions, and used a old saying which related to our learning.

For one reason, I sometimes have late after school activities. I eat dinner take a shower, spend a little time playing and watching T.V. with my family, and have an hour's worth homework. I have to sleep late like at 9:30 to 10:00! I am tired and sleepy! Shouldn't I get a day off if I am still sleepy? I mean if I get too sleepy in the mornings, I might lag behind in class and not pay much attention. That would be bad. Also, I don't get ...

All Over

Picture this, at 8:00 A.M. in the morning, after late night party, you are dragged out of bed expected to walk around and flip on some bars with your hands for a WORLD WIDE CHAMPIONSHIP that you forgot about. One more thing to go with this, ever heard the term " If you fall of the horse, the only thing to do is get back on"? I would love it if you understood WHAT gets you back on the horse. I mean, if nothing did, the horse would stroll away leaving you behind. How? Presenting my independent narrative writing piece with only a few pinches of help! Just read on!
