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.

Properties of Multiplication

Tuesday, September 24, 2013

For the first 30 minutes of class, we went over our test that students took on Friday. Most students did well, while some need to slow down and read questions more carefully. In the next few weeks we will learn an acronym for solving word problems and well as the UPSE problem-solving board.

Students learned about the 4 properties of multiplication today. We discussed Commutative Property, Associative Property, Identity Property and Zero Property of Multiplication. Students took the following notes:

 

 

Students then took turns at their table groups to identify each property of multiplication. I wrote a multiplication fact/property on the board and students held up cards to identify which property I wrote.

 



Multiplication: Notes and Making Arrays

Monday, September 23, 2013
Today students studied the meaning of multiplication. We took notes that included ways to show multiplication:

Students also used color tiles to create arrays from multiplication facts that I showed them on the board.

Here is a copy of tonight's Homework (due Wednesday 9/25, click to download)... just in case you weren't able to obtain it from the database.

Rounding and Estimating Whole Numbers and Decimals

Monday, September 9, 2013
Today students learned how to use rounding to estimate numbers. We learned how to use the Rounding Hill (click to download) to help us round numbers.

Steps for Rounding Hill:
1. Put the number you are rounding to in the box in the middle. Let's say we are rounding 684 to the nearest ten. That would go in the box in the middle.
2. Then we put the two nearest ten in the boxes to the right and left. In this case we would put 680 and 690 (see picture).
3. Underline the place value you are rounding. Look to your neighbor to the right and circle it.
4. If the neighbor to the right is 1-4, you fall back to 680. If the neighbor to the right is 5-9 then you go forward to 690.

 
 

We also went over our vocabulary (click to download) for Rounding and Estimating.


Tuesday, September 10, 2013
Today we continued talking about rounding. We created a class anchor chart for rounding numbers that students will receive and glue into their journals tomorrow.

We discussed rounding decimals. We said that rounding decimals is just like rounding whole numbers... you still follow the same steps!


Reminders: Monday's homework (click to download) is due tomorrow! Also it's picture day tomorrow!!! This time picture day dress code is school uniforms. In the spring students will have free dress pictures taken.

Also, if you can please work with your child on rounding at home that would be great! Give them a few practice numbers to round.

Welcome to Ms. Cao's 4th Grade Math!!!

Welcome! Now that the first official week and a half of school have passed, I finally have some time to create this blog. This year I believe that all of my students can reach their full potential. I hope that with our wonderful parents' help, students will have a successful year in fourth grade math. My purpose of creating this blog is to share with parents the material/content that students are receiving and learning in class. I hope this additional material will help you and your child this school year. I will try to update this blog as often as I can. Here's to a wonderful, fun-filled year!
