Hello everyone.Today in class we talked about Jayden's number line post and we talked about Adding, Subtracting, Multiplying, and Dividing integers.We had to talk about Jayden's number line because the fractions were at the wrong place.
Here is an example of Jayden's picture:
Mr.B told us to talk to our tables and see what's wrong with it.I asked Renz P what's wrong with it and he said that -2/9 should be closer to zero and -4/7 should be after -2/9 i asked him why and he said becuase -2/9 is 0.2 and -4/7 is 0.5 so -2/9 should be closer to zero.Here is an example that Mr.B gave us :
Here is the second one:
He told us to put each fractions in a different number line.
For the rest of the class Mr. B gave us Multiplying and Dividing Integers and told us to give 2 examples for each one.
Multiplying :
(+) x (+) =
(5) x (8) = 40
(7) x (5) = 35
(+) x (-) =
(8) x (-5) = -40
(9) x (-2) = -18
(-) x (+) =
(-6) x (7) = -42
(-4) x (7) = -28
(-) x (-) =
(-8) x (-5) = 40
(-2) x (-4) = 8
Dividing :
(+) ÷ (+) =
(3) ÷ ( 4) = 0.75
(4) ÷ (7) = 0.5
(+) ÷ (-) =
(4) ÷ (-9) = -0.4
(9) ÷ (-7) = -1.2
(-) ÷ (+) =
(-5) ÷ (4) = 1.25
(-9) ÷ (2) = -4.5
(-) ÷ (-) =
(-3) ÷ (-6) = 0.5
(-5) ÷ (-3) = 1.6
Homework for November 3,2009
Page 57,58 and 59 (syk)
and check your understanding (CYU). Then practice page 60 # 4 or 5, and each of # 8, 9, 10 and 11.
Well that's it for me,it took me 2 days to do this please tell me if there's any mistakes,errors or anything at all comment.Thats it for today and now i have to do math homework.BYE!
