Multiplying Integers

first we learned to multiply two positives together. To multiply positives you multiply them. But you have to show your work.

For example:

(+3)x(+4)= +12

to show your work you have to write out: (number) groups of (number)

(+3)x(+4)=+13

3 groups of 4

You also have to model the question. To model you must have a certain number of groups containing a certain number of positives/negatives. But it is not a group unless you circle the groups. Then show that they are arriving

(++++) (++++) (++++)<-------

Multiplying negatives

To multiply negatives you do the same thing except with a negative.

For example:

(2)x(-3)= -6

2 groups of negative 3

(---) (---)<----

If the first number is a negative then the words start with remove

(-4)x(3)= -12

remove 4 groups of 3

to do this we need to have zero pairs

--- --- --- ---

(+++) (+++) (+++) (+++)

then make 4 groups of 3 positives. And then show that the positives/negatives are going away by making a arrow pointing away from the groups.

(+++)----> (+++)-----> (+++)-----> (+++)---->

Julius' Pay it forward

 Julius' pay it forward

Part 1:

Pay it forward is when you do something nice for 3 three people, and they do it for 3 other people and this chain becomes even bigger. You do this to either make them feel good or help them with something.

Part 2a:

My pay it forward was babysitting my baby cousin since her parents were shopping for Christmas. My parents couldn't do it because they were picking up my aunt from the airport. I babysat my cousin for an hour until my parents took over. I did this on December 23^rd.

Part 2b:

I chose to do this because my cousin's parents were away and she cries a lot when her parents aren't here and I wanted to hear her laugh not cry

Part 2c:

I helped my my aunt and my uncle because they were too taken up in the Christmas rush

Part 2d:

I did this on December 23^rd

Part 3a:

there were a few rough spots here and there, since i haven't babysat anyone, but overall it went very well.

Part 3b:

When my cousin laughed instead cried it put a big smile on face and it made me feel very nice.

Part 4:

Pay it forward is something that has probably gone over some peoples head and they just wiped it off as another idea. But this could become something more and if everyone did this the world would feel happier.

Julius' Percent Post

100 is a equivalent fraction out of a hundred

100% is 100 out of a 100, 60 out 60 is a equivalent fraction.

50% is 50 out 100, 25 out 50 is a equivalent fraction. to get 50% you divide by 2. Example: 20=100% 20/2= 10=50%

25% is 25 out of 100, 50 out 200 is a equivalent fraction. To get 25% you divide by 4. Example: 20=100% 20 /4= 5=25%













10% is 10 out of 100, 20 out of 200 is an equivalent fraction. To get 10% you divide by 10. Example: 20=100% 20/10=2%. 

1% is 1 out of 100, 10 out of 1000 is a equivalent.

Represent each percent on a grid.

Converting Fractions,decimals, and percents

26%
divide 26 by 100 to get 0.26 
26/100

7/10: divide seven by 10 to get 0.7 then multiply by 100 to get 70%

0.024: multiply by 100 to get 2.4 %
2&4/10

20% of 60 
0.2= 20*60=12%

20  =  ?    
100    60  multiply 20 and 60 and then divide that answer by 100
