Long Division - DMSCB

This week students have been learning how to do long division. We learned about the acronym DMSCB which stands for Does McDonald's Sell Cheese Burgers? Each beginning letter in that sentence stands for a step that students must take to do their long division.

Remember: The dividend (number inside our division house) is divided by the divisor (the number outside the house) and we ALWAYS put our quotient/the answer on the top of our house or on the roof.

We did 2 example problems so students could get some practice. We also did some more independent practice problems that I wrote on the board. Please review these practice problems with your child.

Here is a really good video for long division that we watched in class:

Here is a copy of today's HW - Homework Wednesday 11/6/13 (click to download)

Reminder: Test on Friday 11/8/13 over multiplication (2x1, 3x1, 2x2 multiplication) and division (basic and long division).

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.

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.

Estimating Sums and Differences of Whole Numbers and Decimals

Thursday and Friday, September 12 & 13, 2013
Students learned how to estimate sums and differences of whole numbers and decimals. Here is a quick and helpful video that concludes what we learned in class.

Remember Monday HW is due Wednesday. Wednesday's HW is due Friday. Friday's HW is due on Monday. Here is a copy of Friday's Homework (note that HW is not posted on the database because there is an error with my webshare folder). There are 2 pages: Reteaching 2-3 and Reteaching 2-4 (click to download).

Remember to round each whole number then add or subtract. Round decimals to the nearest ones place then add or subtract. If students wish to show work on a scratch sheet of paper they may do so and attach it to the homework.

More Rounding & Homework

Wednesday, September 11, 2013
Students continued to practice rounding whole numbers and decimals. Remember the steps for rounding! Remember the rounding rules: 4 or less, let it rest (stays the same)... 5 or more let it soar (add 1 more)!

Here is a decimals place value chart in case students need it.

 

4C students did not get to see me in math class today due to MAP testing, so we will check Monday's homework tomorrow.

 

All students received a copy of today's homework. Wednesday's homework (click to download) will be due on Friday.

 

Parents, please have your child practice place value and rounding at home! Here's a great Place Value Mat (click to download) to practice with.

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.

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!!!

Decimals

Thursday, September 5, 2013
Yesterday, students took their beginning of the year M.A.P. tests. These tests are not taken for a grade. Students take these test for reading, science and math. Students take this test to determine students’ instructional level and to measure academic growth throughout the school year.

Today we continued talking about decimals. We learned a cute poem to remember decimal place value and how to read/say decimals.

We used base ten blocks to represent decimals. The hundreds block represents one whole, the tens rod represents one tenth, and the small ones square represents one hundredth.

We watched the following video:
Writing Tenths and Hundredths with Decimals

(I will try to embed the video to my blog later... it's not letting me at the moment)

This should help with Wednesday's Homework (click to download)! Also, problems A, G, and J did not copy well so they are kind of hard to see, therefore, you may download or view it here. Sorry for the inconvenience.

Extra Practice:
If you would like to practice decimals at home, here is something we used in class:

10 x 10 Grid
Parents can shade in an amount and ask students to name that amount or write a decimal and students have to shade in the amount on the grid. Remember 1 grid equals 1 whole.
