On my way home
I think of a math poem
Addition, subtraction, division, and multiplication
Which will I choose as my inspiration
A number added to another number
Will give a sum for an answer
Adding both positive and negative number
Will give you a sum of an even number
Adding integers is interesting
Like the first time I started singing
Adding both positive will give a positive sum
That`s what I tell them, and they just sit there on their bum
So next time if you want to know something about adding integers
Just remember what I said, because it`s as easy like opening letters.
Dealing with some cards,
Sharing equal numbers of
cards with each player.
Doesn't work for the
negative and positive
Subtracting Integers(Free Verse)
Right after we finished learning about adding integers
Mr. Harbeck told us that the next thing we will learn about is subtracting integers
He said that subtracting is a myth,
To subtract integers you need to add the opposite
After he explained everything
He gave us work to do, and I started subtracting
Subtracting is like adding integers
But using different numbers
When you forget how to do it
Just think, think, think
And it will come to you as fast as a wink!
Rules for Multiplying Integers(Free Verse)
If you want to do better in school
Just follow these rules
When you multiply integers remember not to get confused with the order of operation
Don`t you forget it or you will get the wrong answer for the equation
If you multiply an odd amount of negative integers your product will be a negative
When you multiply an even amount of negative integers your product will be a positive
If you think about it, it`s really easy
just keep on trying until you are sleepy
Chapter 2: Combining Like Terms and The Distributive Property (script)
Characters: Sasha, and JasmineSarah: Hi, Jasmine! So did you finish the questions that Mr.Harbeck gave us for homework?
Jasmine: Yes I did. The answer that I got for the question: n+3-5n+12 is -4n+15.
Sarah: The answer that I got for that question is -6n+15, but I'm not sure if it's right. Can you explain to me how you solved that question?
Jasmine: Of course I will help you. First step is you need to put n and the -5n, and find the answer which is -4n. Then add the +3 and +12 which gives you +15. Next, combine the variable which is -4n with the constants that is +15, and you get the answer -4n+15.
Sarah: Wow! I never knew that it was supposed to be solved that way. At least now I have the right answer. For the second question: 2+4(3n+8), the answer that I got is 12n+10. Could you please help me solve it, to find out if my answer is wrong or right?
Jasmine: No problem! First, you need to keep the 2. Then multiply the +4 and the 3n inside the brackets, giving you +12n. Next, multiply the +4 and the +8 inside the brackets, giving you +32. After multiplying the +4 with each of the terms inside the brackets, put the variable which is +12n in the front. Next, add the constants, which is +2 and +32, giving you +34. Finally, combine the +12n and the +34, and you will get 12n+34.
Sarah: Now I know how to combine like terms and how to solve an algebraic equation with a distributive property. Thanks, Jasmine for all of the help.
Jasmine: You're welcome, Sarah! I'm just glad that you understand everything that I taught you.
CHAPTER THREE: One Step Equation Solving
Here are 4 different equations.
When you are solving a multiplicative type of equation, you need to use ICOBV. First you need to isolate the n, and to do that you need to cancel using the opposite of multiplication which is division. So you divide 3n to 3, and to balance it you need to do the same thing on the other side which is dividing the 6 by 3. N will equal to 2. The next thing you do is verify. To verify you need to rewrite the equation and then replace the n with the 2. Finally, you need to write 6=6.
When solving a division kind of equation you will still need to use ICOBV. First you need to isolate the n. To isolate the n you need to use the opposite of division, which is multiplication. Multiply the n by 4 and balance it by multiplying by 4 four on the other side so you need to multiply the 3 by 4. Your n will be 12. The last step is to verify. Rewrite the equation and replace the n with 12. Finally, write 3=3 to finish solving the equation.
To solve a question like this you will still need to use ICOBV. First, you need to isolate the n, and to do you have to use the opposite of addition which is sutraction. You need to add a negative 9 on the left sideand add a negative 9 on the other side to balance it. Then your n will equal to 26. As always the last thing to do is to verify. To verify you will need to rewrite the equation and substitute the n with the 26 which will equal to 17. Then write 17=17.
For this last equation, you will need to use ICOBV again. First you need to isolate the n, and to do that you will need to use the opposite of subtraction which is addition. You will need to add a positive 6 on the left side, and do the same on the other side to balance it. Your n will be 20. The last thing is to verify it. Rewrite the equation and substitute the n with the 20, and it will equal to 14. Then write 14=14.
