Estimating Products

Monday, October 7, 2013
Students learned how to use rounding to estimate products.
A few things students must remember:
-You must round first before you do any calculations.
-You must round the number that is not the single digit number.
-You must round to the greatest place value.

EX: 7 x 234 = ---> 234 rounded to the nearest hundred is 200 so we re-write the problem as 7 x 200 = ---> then we multiply 7 times 2 which is 14 then add 2 zeros. The estimated product is 1,400.

Here is a helpful video (full screen to make bigger):

Division Notes & Reminder About Parent/Teacher Conferences Tomorrow

Wednesday, September 25, 2013
Today students learned about the meaning of division. Students took notes over division in their math journals. Then students worked with their shoulder buddies to make equal groups. Students were given a problem and they had to draw their Equal Groups (Division Groups) to find the quotient.

 

 



 

Here is Wednesday's Homework (click to download) which has also been uploaded to the database.

 

Reminders: Parent/Teacher conferences are tomorrow (Thursday 9/26/13) from 2-5 pm. Fourth grade teachers will be meeting together as a whole team. We will be having an open door conference. So there will not be a scheduled time to sign up for. There will be a sign in sheet posted outside my door and basically, it's first come first serve. If you feel that the conference may take longer than 15 minutes, feel free to schedule another time after school to meet with us. We feel that this is the best way to hold conferences this year. 

Warm Regards, 

Ms. Cao, Mrs. Cheatham and Mrs. Hanes.
