Chapter One

Sum, Addend
Gaining, Totaling, Increasing
Combining two integers together

Free Verse:Pratt's Integer Law
When your feeling down and feeling blue
Pratt's Integer Law will show you what to do
Now I'll explain
It's very simple you see
When the amount of negatives is odd
Negative the answer will be
When the amount of negatives is even
Take a breath and the answer I will give
Don't get into a panic
The answer will always be positive
Now don't think that's the end
Because there's one more thing I have to say
When the equation has a zero don't go crying
The answer will then be zippo, natta, nothing
Now your glumness is blown away!

Free Verse:Subtracting
Kind of gives you a sting
Isn't what you predict
Really is adding the opposite

Free Verse:Quotative Division
Quotative Division is a breeze
I will use the numbers six and three
To explain what you will soon read
Two goes into six
How many groups of two does that leave you with
If you guessed purple monkey you got it wrong you see
The amount of groups is actually three

Picture:Partitive Division

Chapter Two

Jimmy: Hey Sue, how are you today?
Sue: I am great!
Sue: I have a question for you
Jimmy: Shoot
Sue: Okay well its two questions from my math homework. I think I know the answers but I'm not to sure if they are right.The first question is n+3-5n+12 the answer I got for it was -6n+15. Is that correct?
Jimmy: Actually Sue that is the wrong answer. I'll show you how to get the right one. Well first you have to group the alike terms. So it would look like this n-5n+3+12. Then what you want to do is figure it out so the simplification would be -4n+15.
Sue: Oh I see how you got that!
Sue: Now for the next question. 2 + 4(3n+8). I think the answer is 12n + 10. Now that must be right.
Jimmy: No I'm sorry Sue that isn't right. I'll explain it again. This is called distributive property. First you have to multiply 3n by 4 and then 8 by 4. That gives you 2+12n+32. Next you have to group the alike terms. So it would look like this 12n+32+2. Finally figure what every thing equals put together and the simplification would be 12n+34.
Sue: Thank you so much for helping me!
Jimmy: Your welcome.

Chapter Three

What I did first was I isolated the variable. I did this by dividing 3n by 3. To balance i had to do the same to the other side. That left me with n=2. The last step is to verify.

For this question I again started with the variable. I did this by subtracting five on both sides which also created balance. The answer i got was x=8. Then i ended with verifying.

I started off with isolating the variable. I did this by multiplying 7n by 7. I did the same thing to the other side. What I was left with was n=14. I then verified.

For this equation I started with isolating the variable. I did this by adding 11 to q-11. For balance I had to do the same thing on the other side. This left me with q=19. To finish it off I verified.

    I really like how you did the free verse for the law. I liked how you made it rhyme and explain on how to do it at the same time. keep up the good work.

    I like the color choice . And I like the Pratt's Integer Law Poem the best. But i think the others are just as good. Good Job again.

    Hi Charissa, I really like your poems, I could see you worked really hard on them, and like what Francis and Gian said about your free verse poem on the law, it was really good. Also, another thing that Gian has already pointed out, was the use of your colours. Well anyways, good job, keep up the good work !

    Hey Charissa, awesome job on the poems. I really enjoyed the free verse on "Pratt's Law" or I guess your law. Well anyways I liked the vocabulary you used in that poem.
    I also really liked the picture poem. I found that pretty cool the way you made it shape in to a division sign. I wasn't sure what it was at first then I saw it after 5 minutes. Well, good job.

    Nice, my favourite is the Pratt's integer law. I like the picture one too, it took me a while to figure out that it was a division sign lol.
