Pre-Algebra - Ms. Pope
In the Pre-Algebra class, we learn a new lesson every single day. Math is obviously one of the subjects that has been taught since you were in school, whether it be something from learning the numbers to solving different kinds of equations. Pre-algebra is a very important class to be in, because not only does it help in different classes and subjects, but it can help you with certain situations that you deal and will commonly deal with in your life.
We have been learning about inequalities and how to graph him. As demonstrated on the left, those are the four symbols used for inequalities. The real problem I have is probably graphing it. Currently, we are doing these in an equation with multiplying and/or division. There isn't a different subject I can connect this to, because it really just has to do with math standards.
The way we graph these inequalities is by first solving them as an equation. The symbol being used is basically an equal sign. Like an equation, solving includes having to do the inverse operation. For example, 4x<24. You divide 4/4, which leaves x alone. You must divide 24/4, which is 6. The final answer is x<6. To graph this, you make a number line and place 6 in the middle. Then, you put greater numbers to the right and the decreasing numbers to the left. Since the answer's symbol was less than, you must point the arrow to the left. If the symbol doesn't include "equal to", then the cirlce is open. My reflection on this lesson is that it really doesn't help us in real life, but it still is important to know in class. |

Fair Game PresentationFor Pre-Algebra class, we were required to make a presentation based on one of the lessons that were listed. I did "Fair Game?" and made a slideshow. The lesson had to do with probability.
For this slideshow, I used Google Presentation. It's a reliable tool for making basic slideshows and such. I can only compare this lesson with Computers, because that is what I used to create it. So basically, the lesson had to do with the probability of landing a certain number. Using a chart, we had a few numbers and had to fill the rest in. Basically, we had to figure out the probability of landing a certain number. It's easier to look at the presentation than for me to explain it. |
