Math Review answer keys on Office 365.

Hi Everyone,

I shared the answer keys with everyone on Office 365.  Your password is the same one you use for everything.  Austyn and Tyson, you are not on Office 365.  Send me an email at jwallach@sd19.bc.ca and I can email them to you directly instead.

See you tomorrow for the review!

These are the rules we've covered so far...

Should have finished all homework in class as I didn't give you a lot.  Play a game of crib, a game of cards, a brainbasher, a logic puzzle, or some other math/solving style game this weekend :)

Adding, Subtracting, Multiplying and Dividing Rational Numbers

• When adding and subtracting, you need to get a common denominator, then + or - numerators
• Always look to see if you need to reduce your fraction

• When multiplying, multiply numerators and denominators
• Always look to see if you need to reduce your fraction
• If you can reduce the fractions BEFORE multiplying, it helps make your answer easier to reduce

• When dividing, take the reciprocal of the second fraction and then multiply (flip and multiply)
• Always look to see if you need to reduce your fraction

HOMEWORK:  Both sides of the white sheet ( adding, subtracting and dividing) and either side of the green sheet (multiplying)

Monday, Sept 11

Today we reviewed working with Rational Numbers (aka fractions)

• a rational number can be written in form a/b, where a and b are integers and b cannot be 0

Multiplying or Dividing the numerator and denominator by the same number does NOT change the number because you are really multiplying by 1.

When putting rational numbers in order either

• find a common denominator first and compare numerators
• put into decimal form first

HOMEWORK:  PG 11/12 # 1,2,3,4,13,16,17

September 8th

Today we reviewed the divisibility rules:

Homework:  A few of you still need to bring in your item for our Math Quilt Bulletin Board.

Do some math or a puzzle:  crib, farkle, cards, brainbasher logic game, logic puzzle etc...(will be our attendance question on Monday) :)

September 6th

Today we worked on solving puzzles and getting our brains working.  We learned how to do two different Japanese logic puzzles:

• Futoshiki
• Kakaruso

We used the iPad's to go to the logic puzzles section of brainbashers to try more puzzles.  If you'd like to try more, here is the link  https://www.brainbashers.com/logicpuzzles.asp

Homework:  You need to bring in a puzzles, math quote, math joke etc to put on your square in our Math Quilt. :)
