What I learned in 6th Grade
By: Caroline LaRusso
Ratios!
A ratio is what you use to compared two different numbers to each other. This is a ratio of the number of boy to girls in my 6th grade class and under this is just some more ratios and it will show you how to do them in the picture in the middle of the other two ratios. Ratios can also be simplified!
The ratio 3:1 is also 6:2!
As you see here you just double it.
You can do the same with 4:5 and 8:10
Rate!
This time lets just show you a quick video on how to do this skill! Go to Learn Zillion and type in the search bar 614 and it will show you how to do this skill.
Unit Rate!
For rate, lets solve the problem beside this description. I will show you the steps to competing this problem below. These steps will explain to you how to do this. Rate is pretty much just a ratio (shown above) with some kind of rate in it. Here are some examples of some unit rate units.
mph or distance.
Step 1
You divide 200 by 10. When you do this you should get... 20 and so what you get from step one is 20.
Step 2
After you get 20, you make sure to put your UNIT RATE on it. Your unit rate for this problem is... $.
Step 3
Then you put on your paper or answer sheet...$20. Which makes you get 20 dollars for every hour you work at the bank.
Measurement Converting
Measurement Converting is really easy and usually you really don't have to do much you just convert them. Here is a chart of measurements and their conversions to help you.
Decimals
Below this is what decimals looks like. Really you can do a lot with them but you will find out all of those later.
A positive integer
Well... this is just a number... but we have to obviously make sure that it is positive. The first picture is WRONG and the others are right.
Negative integer
Well... this is just a number... but we have to obviously make sure that it is negative. The first picture is WRONG and the others are right.
Number Lines
Well... It is not rely hard to explain number lines because they are just...well... numbers on a line.
Graphs
It is hard to explain these so, I just gave you a IXL on them and it will show you how to do it.
Inequality
This is just like 4 < 5. You know about those right here is what one looks like.
Percents
Percents are just like this...
50% of 100 is 50
or...
75% of 100 is... what?
Here is what one looks like...
Greatest Common Factor
This is just where you find two numbers GCF.
Greatest
Common
Factor
Tables and Charts
They are very hard to explain but here is a learn zillion link of them and how to do them.
Rectangular Prism
This is just a prism which is a 3d shape but this 3d shape has a base that is a rectangle.
Statistic Questions
This is when there can be MANY answers to a question. Like... what are the ages of all of the kids in sixth grade this would be a statistic question because you could have to answers... 11, 12, or even 13.
A set of Data
This is just a few numbers really that is all. They all have a space and a comma in between all of them.
A list of numbers
I would hope you know what a list of numbers is but if you don't know how to find the three m's of the list of data here is a video and some pictures of how to do that.
Exponents
This is just a number smaller and higher than the other number. The smaller number is the exponent. This shows how many times to multiply the bottom number by the same number.
Volume
Sorry I can't really explain this so here is some example below and a buzzmath link for you.
Least Common Multiple
For this you do your prime factorization and then compare the two to see what the LEAST COMMON MULTIPLE is. Here is a picture of how to do it.
