Week 11 ~ Geometry

This week we got into geometry, which has always been my worst subject of Math. The object is to take a shape or a polygon and find the area, volume, perimeter, radius, etc. I have never been good at this, I never understand how to find these things or remember the formulas to do so.  Here is a site that might be some help to you, but so far nothing has helped me.

Week 10 ~ Measurements

This week in class we got into measurements, like liters, grams. pounds, etc. These measurements are a lifelong tool everyone at one point or another will use. I understand the concept of measurements but remembering all the different conversions gets a little tricky. Here are some games that may help you with measurements.

Week 9 ~ Scientific Notation

This week we are learning about ratio's, percents, scientific notation, irrational and real numbers. Irrational numbers are any numbers that CANNOT be expressed as a fraction. Real numbers are all numbers that are on a number line. Scientific notation is something we can use to make very large or very small numbers to make them easier to deal with. for example take the number 10000 you need to count all the zeros and is should look like this. 1 x 10^4. Other numbers like 0.00089 you have to move the decimal point to make it a number between 1 & 10 so it would be 8.9 and since the zeros come first it should look like this,               8.9 x 10^-4. since you are moving the decimal point back to 8.9 that is what makes it a negative.

Here is a chart below that explains how to multiply and divide in scientific notation form. Here is also a link for a cool way to practice you scientific notation logic.    Scientific Notation Practice

    

School House Rock

When I was a kid in school in order to help us learn our times tables my math teacher would put on these school house rock video's and at first I thought they were a little silly but looking back I relized that putting that stuff to music really helped me and sometimes all these years later I find myself singing those songs when I forget.

*There were no video's made for numbers 1, and 10

Week 8 ~ Decimals

This week we went over decimals and rational numbers and how to do basic operations with decimals, like adding, subtraction, multiplying, and dividing. Basically rational numbers is just any number that can be put in a fraction. Adding decimals is easy all you have to do is line up the decimal points and add straight down like you normally would but remember to keep the decimals lined up. Subtraction is done the same way but remember to fill in the blanks with zeros that can help. Multiplying is pretty easy too all you have to do is line up the numbers multiply normally then count how many  spots the decimal point was in each number and add that many to the solution. For example 2.33 x 2.4 = 3 spots so take the solution 5592 and move 3 spots = 5.592. Division is where I have trouble, first just ignore the decimal points and long divide like normal. What you have to remember is to put the decimal point in the same spot as the dividend.

Here is a few reminders of how to convert fractions to decimals and decimals to fractions

Week 7 ~ Fractions

Today I did my IBL and everything seemed to go good, and everyone seemed to like it. I enjoyed doing the IBL but I’m glad it is finally done and over now I can focus on the rest of the work.
Today in class we talked about integers, intro to fractions, and operations with fractions. We learned what a fraction is how to make up a fractions and how to add, subtract, multiply and divide. Fractions have always been a bit difficult for me so these are some games I found that are helpful...........

I also found this other site that’s pretty cool; it divides all the math games by subject....

Week 6 ~ Factoring

This week we learned about factorization, lowest common multiples (LCM) and greatest common factors (GCF) this has always been a tough subject for me I have just never been good at factoring or multiplying for that matter. Your times tables are really important when it comes to factoring. If you can find all the multiples of a number in your head then your golden, but I am not ones of those people I have always had trouble remembering all the different numbers. However I have found something that works for me, the factoring tree. The factoring tree can be a bit difficult at first but once you do it it’s pretty easy. First you put the number you want to factor at the top. Let’s say number 36 then we see if it can be multiplied by 2 then we right 2 on one side 18 on the other. Next since the number 2 does not have two multiples then you do the 18 and so on until you can’t anymore. At the end you should have a picture like this.......

Then you find that you factors are 2,3,9,and 18

I also found some really cool games that are mall about factoring, here are the links....
