Geometry Unit --- Points, Lines, Angles

Points, Lines and Angles
Students started our geometry unit learning about points, lines and angles. Students made foldables in class that were glued into their math journals.

 

 



 Students also learned how to name angles. An angle can be named by using a capitalized letter to represent it or 3 capitalized letters as seen below:

Fractions --- Reviewing the Basics

Tuesday, January 7, 2014
Today students learned about fractions. We revisited this topic from last year and discussed the basics of fractions. Students took notes in their math journals.

We also used the smart board to identify fractions.

Model Drawing

In addition to our other strategies, students learned about drawing models/pictures. Students took notes in their math journals. There were 5 simple steps:




 



If students can utilize these strategies, I believe that they can be successful when working with word problems.

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.

Ordering and Comparing Decimals

Friday, September 6, 2013
Today we learned how to compare and order decimals. It's similar to comparing whole numbers, but just with decimal place value. We learned two ways to compare decimals. One way is to look at each place value to determine which one is greater or less. The second way is to line up the decimal point. Students also got to use hundredths grids on our mimio board to compare 2 decimals.

Students glued a copy of our anchor chart into their interactive math journals. See below, except their chart is black and white

 



 

Refer to the above material if your child needs help on their Friday Homework. Please omit number 8 on the last page of the homework. Have a great weekend everyone!!!

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!

Friday 8/23/13: Interactive Math Journals
We decorated our Interactive Math Journals :) and created the Table of Content

Monday 8/26/13: Place Value to the Hundred Millions
We set up our interactive math journals and glued in our place value charts. We wrote vocabulary words on the inside flap. We also played Display the Digits. Click link to download.
For this activity you will need Number Tiles, click to download.

     

Tuesday 8/27/13: Place Value Graphic Organizer (aka Foldable)
We created a graphic organizer to help students differentiate Standard, Expanded and Word Form. Inside each flap is a short definition and an example.

 

Wednesday 8/28/13: Comparing Numbers

We took notes and practiced comparing numbers.

Thursday 8/29/13: Ordering Whole Numbers

We learned how to order numbers. We also practiced ordering whole numbers from greatest to least and least to greatest. We also did a group activity where students had to order and compare numbers - Think Together. Click link to download.
