Math evaluation tomorrow

12/17/2019

1)POST A RESPONSE:

Watch this video (click) to review estimating adding and subtracting fractions. Use the strategy of rounding to zero. 1/2 or 1 to estimate the answers to following questions. Ask any questions you have about Math here! STUDY HARD!

SUCCESS CRITERIA:

Show your rounded fractions and estimated suns and differences.

EXAMPLES:

EXAMPLE 1: 2/9 + 3/7 = 0 + 1/2 = 1/2

EXAMPLE 2: 9/10 - 1/3 = 1 - 1/2 = 1/2

A) 4/5 + 1/3 =

B) 3/4 + 1/8 =

C)19/22 + 6/13 =

D) 3/7 - 1/8 =

E)15/16 - 8/17 =

F) 6/7 - 35/38 =

@Mr. Fisher
In the video, it also teaches us how to divide and multiply estimated fractions. Am I correct in assuming that we DON'T need to do this tomorrow?

12/17/2019 06:55:33 pm

i don't think that we have to do it

Mr. Fisher

12/17/2019 08:44:46 pm

@Emily-You are correct. Only adding and subtracting tomorrow.

@EVERYONE- I sure hope no one is copying and pasting another students work. That would defeat the whole point of this PAR, which is to think and practice estimating. Your INTEGRITY will remind you:)

Keep working hard, amazing div1. I believe in you!
