Welcome to Mrs. Turquand's Math Website


Welcome to 7th Grade! 
I love having you in my class. 

I hope you have a fantastic school year! 

News of the week: Mar 2-6




*** 1 weeks left to get all work caught up for this trimester. Last day to submit late work Friday the 6th. Trimester ends on March 13th. 

Tutoring Monday and Thursday this week. 

Period 2,4,5,6:  Investigation # 25 is due completed this week. We are starting our lessons on solids. Surface area and volume will be studied for the next couple of weeks. 

Period 3: Our unit on Probability will start this week.  






Your homework is listed on the calendar. Make sure to click on the link.




All homework is due on the next school day unless otherwise noted.  



Geometry Formulas that you need to memorize:


Square and rectangle:    A = length x width


Triangles:                       A = (base x height)/ 2          


Parallelogram:               A= base x height





Circles:                       A = Pi x r x r

                                   C = Pi x d     or Pi x 2 x r



 Adding :

   Think if adding as putting two quantities together...

            If you add a  + number and a + number =  + number

            If you add a  - number and a - number = - number

            If you add two different kinds of integers... 

                recall how we went back and forth on the number line, 

                or how we drew pluses and minuses

                ex:  -6 + (+2) = -4

                  - - - - - -   and ++   =  - - - -  there are more minuses            


         Subtracting:  Add the opposite

               ex: - 5 - (- 4)  = - 5 + (+ 4) = -1   

               change the problem to an addition problem 


         Multiplying/Dividing : They have the same rules

            ex:  Two  - numbers produce a + answer   ex:  -5 x -5 = +25

                  Two + numbers also produce a  + answer  ex:  +5 x +5 = +25

                  A      +   x   -  producers a - answer.    ex: +5 x -5 = -25



Fractions to Decimals....

                      In and Out


Fractions to Decimals to Percent... 



Decimal Rules

When you don't see the decimal it's on the end,

             Why? If you don't see the decimal, it is a whole number. 


When you add and subtract line up the decimal. 

              Why? Place value rules must be respected


When you multiply move the decimal when you are done. 

               Why? Because you are multiplying parts of a whole 


When you divide make the divisor a whole number by multiplying by a multiple of ten. Multiply the dividend by that same multiple of ten. 

              Why? It is easier to divide by a whole number. 




Adding and Subtracting: 

                Make sure you have a common denominator. 

                How do you find a common denominator... list all the multiples and find one that's common to all denominators

*** Special notes for subtraction... if you can't subtract because the first fraction is smaller than the second fraction, remember to regroup. 




               Multiply numerators and denominators. 

               Mixed numbers... first turn them into improper fractions (see you notes)... then multiply numerators and denominators. 



              Multiply by the reciprocal. (reciprocal... flip the fraction)

              Mixed numbers... first turn them into improper fractions, then multiply by the reciprocal. 


Happy 2019!
