The independent work time has been less efficient than I would like and the packets are not close to being done. This week, I'm sending them home with the kids tonight. I'm assigning 30 minutes of math work on the packets. My goal is that they get more practice on the math work not that the whole packet gets done.
The standard is using efficient ways to solve division problems.
Problem c of the half page is 631 / 17
to solve this I start by rounding 17 up to 20
Then I think 20 x 30 = 600
To start my dividing I can take a chunk out of 17 x 30
17 x 30 is 510
Then I find the difference: 631-510 = 121
So all I have left to do is find out how many times 17 goes into 121
If 17 x 10 is 170, then 17 x 5 is 85
Find the difference 121 - 85 = 36
2 x 17 = 34
36-34 = 2 that's my remainder
I've used these clusters
17 x 30 = 510
17 x 5 = 85
17 x 2 = 34
So 17 x 37 = 629 + 2 = 631
Or 631 / 17 = 37 R 2
This seems really long and drawn out, but when it is done on your student's paper it is done in just a few steps that makes sense.
Tomorrow, the kids will get their homework packets and they will be Due next Thursday.
Thanks
