Mr. Kimbley assigned us a game and it was a very hard game and I learned some more things about doing math in my head like I'm not always right and that it's really hard to do. So I played the integers level and I found out that I need to work on that level so I will start working on that.
I also learned in the Fractions that I need to work on that. I couldn't add 1/2 and 2/3 in my head so I tried to bring out the scratch paper, but my mom didn't let me. She actually liked that game so now she's going to show it to all my old teachers. I also played the decimals too. It was very fun.
Have you ever wondered why when you graph inequalities you either open the circle or close the circle? Wel, I have the answer.You close the circle when you have the signs: less than or equal to and greater than or equal to. You close the circle because the everything is included. When you open the circle its because you aren't including the number below the graph.
Today in math I learned how to take a decimal that goes on forever and make it an equivalent fraction. Ms. Pope taught us a great shortcut that tells us to find out how far the numbers are behind the decimal. Then put subtract one. Then make that the denominator. Ms.Pope taught us very well but, it took everyone till the second problem to get the whole method, including me. I really like math and it just gets easier as we go on.
I think that the denominator gets bigger, and the decimal gets smaller because the decimals are not whole numbers. Also, because the denominator may need to be reduced more. Just like 1/4 is .25, or 1/8 is .125. Finally because the denominator is divided by the top number and that is usually smaller that the denominator. So now you know why the decimal gets smaller when the denominator gets larger.
Have you ever wondered why there is an infinite amount of numbers inbetween 1 and 0. Well I can tell you.
There is an infinite amount of numbers between 1and 0 because there are decimals and fractions between every number. Also because the numbers never stop like infinity and. My mom says that's the only reason that there is an infinite amount of numbers between 1 and 0. Here are some examples: .1 .2 .3 .4 ect. There are more but it would take forever and a day.
Today math is the key. Math is used everywhere and anywhere you go. Have you ever wondered why there is no such thing as dvision in a problem such as 2x=16? Well I am going to tell you.
Well, in the problem you multiply 2 and x. You aren't multiplying because you want to undo the problem. So you divide. First you divide 2 by 16, and you get 8. That's why there is no division in the problem. So if you did't get it there is no division in that problem because you undo the problem and it's a multiplication.
In math there are methods that you can use to solve problems or answer a multiple question problem. One I would like to tell you about is what we call Communitive property. You use it to move around the numbers so that you can do the problem in your head. A problem like: 5+4-2+6 could be changed into 6+4+5-2 which would be 13. Its that simple!!
