Math Midterms!

Intro to the dreaded... Math Midterms

Hi, everyone! One of the most dreaded thing in ANY year of school is- the Math Midterms.I personally highly dislike the midterms. It is a lot of stress, studying, effort, and hard work. But, I have some tips and tricks I have learned over the years of the best way to study for these midterms. I am also going to be explaining some of the topics on MY 6th-grade midterm for you all! I hope you find this study slideshow resourceful and helpful! If it sparks questions or confusion, be sure to let your teacher know to clear the air! Have fun!

First off... Study tips!!!

Before going through the 6th-grade math topics and walking you through problems, I am going to share my valuable and slightly secretive tips on how to have a good study session and the best way to manage your time.Once my teacher gives me the test date, I write it down on my calendar, with the red marker and circle it. This way, I know I need to study and prepare for it when it comes. When I receive the study guide for the test I write down all of the topics somewhere I will know to check. I feel typing it on a google doc works best for me, but you can try different ways and see what works for you! The very next thing I do is create a study schedule. My midterm is next Tuesday, so I split up all the topics and make sure I cover each one and not feel burdened on 1 specific day because there is "too much." This is my BIGGEST tip and probably the most helpful!Now.... for the actual MATH!!!!! :)

Table of Topics!

1. GCF&LCM!2. Absolute Value3. Multiplying and Dividing Fractions4. Volume

GCF!

What is the GCF of 18 and 36?So, my first tip is to BE NEAT! You must show your work and be legible so your teacher can read it! I start by writing down all the factors of 18 and 36. Try and go in order.... that will make it much easier. Go through each number slowly!18- 1, 2, 3, 6, 9, 18 36- 1, 2, 3, 4, 6, 6, 9, 12, 18, 36So, as you can see there are a few common numbers between 18 and 36! Carefully stare at the factors and circle the common ones. I see 1, 2, 3, 6, and 18 all common. But, the greatest one is 18.  So, the GCF of 18 and 36 is 18!Don't get it? Comment your problem and I will try to answer it! But always, always, ALWAYS ask your teacher is this problem is confusing, because MORE THAN LIKELY you WILL see it on your 6th grade Math Midterm!!!!

LCM!

What is the LCM of 9 and 10? To approach this problem, you need to write out the multiples of 9 and 10. You should know what multiples are. If you do not, they are just the products to multiplication problems, basically. Such as, multiples of 5 would be 5, 10, 15, 20.... etc. So anyway, start off by listing the first 5 multiples of both 9 and 10.9-9, 18, 27, 36, 4510- 

Absolute Value

Note to reader- *There is a specific sign for absolute value. It is 2 vertical lines surrounding the number. Since I can't show that from my laptop, the questions is just going to be, what is the absolute value of (blank)*What is the absolute value of 8? To start, let's go over the definition of absolute value. Absolute Value- the number of spaces away from 0.When the question is asking what the absolute value is of 8, just count how many numbers that is away from 0. 8 is 8 spaces away from 0, so 8 is our answer.Easy, right? Well here is a more complex problem...What is the absolute value of -4?NEGATIVE 4????!!!! Do not panic! This is way easier than it looks! Just remember that the absolute value can NEVER be a negative number. It is ALWAYS a positive number (4, 5, 6, etc.) Just think to yourself- how many spaces is -4 away from 0? 1, 2, 3, 4! The absolute value of -4 is 4, because -4 is 4 spaces away from 0!Don't understand? Let a parent, teacher, or trusted adult know! This will 100% be on your 6th-grade math midterm! 

Multiplying Fractions

This is an easy peasy topic!!3/4*4/5You may not be aware, but * means multiplication! So all you do to solve this problem is multiply the numerators and denominators together! 3 times 4 is 12, so there is our numerator. 4 times 5 is 20, so there is our denominator. 12/20 is our answer! BUT! WAIT!!!!!!!! We have to simplify! To simplify, simply divide a number that goes into both 12 and 20. I picked 2. 12 divided by 2 is 6, and 20 divided by 2 is 10. 6/10! But can it be simplified more? I think it can! Let's try to simplify AGAIN by 2! 6 divided by 2 is 3, and 10 divided by 2 is 5! Our final answer is 3/5!3/4*4/5= 3/5

Dividing Fractions

5/6 divided by 3/4So, this can get a tad confusing for some people, so make sure you come into this kind of problems with open minds. For this lesson, you will need to know the definition of reciprocal.Reciprocal- the flip of a fraction. For example, 2/3's reciprocal would be 3/2. So, to solve you take the SECOND fraction in the division problem and change it into its reciprocal. 5/6 divided by 4/3Next, you would MULTIPLY. Remember, to multiply simply just multiply the numerators together and the denominators together. You should get an answer of 20/18. But we have to simplify! 1 2/20. Is that correct? NO!!!!! We have to simplify MORE! 2 goes into both 2 and 10! Our final answer is 1 1/10!If you don't get this topic, leave your questions/concerns in the comments below! But please do not hesitate to ask a teacher, parent, guardian, or older sibling for help! They are there to help you!

Volume

This specific math term scares a LOT of people! And don't worry! It is actually REALLY easy! So, basically to solve this volume of this you HAVE to remember the formula! Volume= b*h*wSo, here are what the abbreviations b,h, and w mean: B- baseW- widthH- heightThe base is usually the bottom or the BASE of the prism. In this case, the base will be 6 cm. The height is just the height of the figure, not really too hard. The height is 5 cm. The width means how WIDE the prism is. Usually, it is written right under the height. The width is 4 cm. Now, all you have to do is multiply all of them! This isn't too hard of course, but make sure you do it slowly!5*4*6=120!The volume of this rectangular prism is 120 centimeters cubed.

THE END!

I hope this was informational and helpful to you! If it was, be sure to leave me a comment so I know next year to focus on 7th grade midterms! THE END!!!!!!!!
