Hello Again: Valentines Day...

Sorry I haven't posted anything in quite a while. Life and school has been pretty busy. I do want to let you know that we are having a party on Tuesday to celebrate Valentines day as well as the January, February and June birthdays. So if your kid has a birthday in either of those months, Tuesday is a great day to bring in treats to celebrate. Garrett's mom will also be doing a craft that afternoon with the kids.

Remember to have your kids bring in Valentines boxes made of recycled materials.

Enjoy the 3 day weekend!

Homework tonight

Math workshop has been going really well. I am seeing some real progress in the students fluency with division. This week a majority of the kids passed or exceeded the pretest. The post test is tomorrow as it is every Friday.

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

Homework

Thank you DeBorde Family for your comments,

First of all, we are taking this week off of homework. As for the more difficult problems on the multiples of 10, 100, 1,000 page here is how to solve one of the problems.

#8) 240,000 / 4,000
First we can simplify the problem by crossing off the zeros that each number has in common
4,000 has three zeros at the end... so we can take off those three zeros and three zeros off of the 240,000
Now we have 240 / 4
Next I can use what I know about multiplication
4 x 6 = 24 so 4 x 60 = 240
if 4 x 60 = 240 then 240 / 4 = 60
240,000 / 4,000 = 60

#15) WE need to Estimate each quotient
17,400 / 92
First we change 92 to a FRIENDLY # like 90
Then we change the dividend 17,400 to a number COMPATIBLE with 90
9 x 2 = 18 so we can change the 17,400 to 18,000
Now we have 18,000 / 90
Then we can use multiplication to help solve division
90 x 2 = 180
90 x 20 = 1800
90 x 200 = 18,000
18,000 / 90 = 200
(How close is our estimate 17,400 / 92 = 189.13)

Hope this helps with the homework.
