PEGGY AND MARJO'S ALGEBRA QUIZ / PERCENT PAGE

( sorry, my quiz is kind of short compared to marjo's ! )

 


 

SOLVING ALGEBRA

- using division and multiplication

 

STEPS : 

1. BALANCE

2. ISOLATE THE VARIABLE

3. CANCEL USING THE OPPOSITE

4. BALANCE

5. SIMPLIFY

6. VERIFY

 

               

 


 

ADDING AND SUBTRACTING

 

for example :

10 = N + 6

         or ..

N + 6 = 10

 

 

 

 


 

2 STEP EQUATION SOLVING

 

 

 

STEP 1 : cancel the interger

- balance then simplify

 

STEP 2 :

cancel multiplication ( x ) or division ( รท )

- balance then simplify

 

( STEP 3 : )

YOU HAVE TO VERIFY YOUR ANSWER

 


 

USING ALGE-TILES

 

     

 

 

 

           

 

- i accidently put a  " + " before the 7's but i'm too lazy to change it .

 


 

PATTERNS AND RELATIONS

 

 

 

x. figure #

1  2 3 4  5  6
y. # of blocks 2  4  6  8  10  12

 

X : starts at 1 goes up by one

Y : increases by 2,  even numbers

 

figure number x 2 = 2n      

( n = figure number )

 

- WHEN MULTIPLYING YOU NEVER PUT ' N ' BEFORE THE NUMBER
