Division Area Model Help!!
Below is a link to a video that explains how to use the area model with division, for the most part. I have also placed an example from what we have done in class to show you the difference between the one in the video and the one I show in class. The quotient in the video's area model is on the side, whereas mine is on the top. :)

Multiplying Fractions
In fifth grade, students are introduced to multiplying and dividing fractions; therefore, they must be able to "show" what they know through models. Below are some videos and pictures of how they should be able to show their work and explain it.

Dividing Decimals with Models
Students are able to show the model of division or do the algorithm, but are STRUGGLING with connecting the two!! Please look at the pictures below and work with your child at home. I'm pulling groups this week, as well as doing a quick problem of the day each day. Thanks for your support!

Check out this preview for Classifying Triangles!Dividing DecimalsCheck out the videos below on how to divide decimals with models. A common mistake I am seeing with students, is that they aren't sure how to write their answer- should it be a whole number or a decimal. We have discussed how the whole number represents how many "groups," so if you are trying to find how many groups, then your answer will be a whole number. If you know how many groups, then you are really asking how much is in each group, which would be a decimal since we are dividing decimals. :) Hope this helps!

Multiplying DecimalsHere are some videos on multiplying decimals. I like the models in these videos, but do not like how they set up the algorithm. I teach my students to ALWAYS put the most numbers on top!! For example, 7 x 0.15-> The 0.15 would go on top of the algorithm problem, and the 7 on the bottom of the problem.

One thing I always say is....WHAT are you starting off with in your hands?? How many or much of it? THEN, what do you do to it? For example, 2 divided by 1/4-- I am starting with 2 whole brownies in my hands. I need to cut each brownie into 1/4s. How many of those 1/4s will I have? I will end up having 8 pieces total.

-----New School Year-------
2014-2015
Year in Review
Students are getting a sneak peek of middle school by moving to different rooms for math and reading. The whole 5th grade is reviewing the same topics on the same days.
Last week we reviewed:
Place value vs. value, comparing decimals, order of operations, multiplication, and division with partial quotients
This week we will review:
Rounding decimals, adding, subtracting, multiplying and dividing decimals with word problems
All homework will be given by Mrs. Baltes and will go with what we review for the day. :)
EVERYTHING is REVIEW!!

Multiply and Divide Decimals
Since decimals and fractions are the same thing, you can multiply and divide decimals just like you do fractions!! The only difference is that you use a tenths or hundredths grid. See the math journal for notes.
Dividing Fractions :)
There are 3 different ways we divided fractions:
Whole divided by a whole- 3 / 2 When you divide a whole number by a whole number, it is the same thing as starting out with a specific amount of items, then dividing it between that many people. So, if you had 3 items and had to split between 2 people. Each person could get 1 item and have to split the other item in half, which would give them one and a half each! Or 3 halves.

Whole divided by a fraction- 4 divided by 1/2 When you divide a whole by a fraction, it is like saying I have 4 items and want to see how many halves I can get out of that! Therefore, I would count every single half in all 4 wholes, and would come up with 8 pieces.
http://www.lessonpaths.com/learn/i/multiplying-and-dividing-fractions-2-of-5/divide-whole-numbers-by-fractions-using-the-reciprocal-6ns1-learnzillion
Fraction divided by a whole- 1/2 divided by 3 When you divide a fraction by a whole, it is like saying I'm starting off with a 1/2 of a box and I want to share it with 3 people. How much would each person get? If I split the 1/2 into 3 parts- it would be just like multiplying 1/2 x 1/3 because I am taking 1 out of 3 pieces from the 1/2. This would give me 1/6 of the box.

Multiplying Fractions!
Multiplying Fraction by Whole Number- We studied this last week. Basically we are just saying it is the fraction SO MANY TIMES (which represents the whole number. For example, 1/4 x 3 is 1/4 three times, which equals 3/4.
Multiplying Fraction by Fraction- This is the current week's lesson. Basically, you are taking part of a part. For example, if I wanted a 1/2 of a 1/2 of a brownie (1/2 x 1/2), I would end up with 1/4 of the brownie.
Multiplying Mixed Number by Mixed Number- This is also the current week's lesson. Basically, you are taking part of a part again, but with bigger portions. This video explains it, but is kind of long. IT REALLY does go over it well though.
Extra Work for break!
Here are some extra problems to work on over break...(Answer key is in a word document attached)
REVIEW- Add and Subtract with Decimals
(Grids and Base Ten Drawings)
Here are some examples of adding and subtracting decimals in the grids and with base ten model drawing. Basically, adding is just putting the two decimals together. Subtracting is taking one decimal amount from the other. ALWAYS draw the first decimal first, then add or take away the second decimal. The first picture is the base ten model drawing (adding):

What's the Problem? The Word Problem that is!
Many students get tripped up when we add words to problems. It is SUPER important for them to do the following things when they are solving word problems....
1. Read the problem at least 2 times before you start solving.
2. Underline the important information and circle what it is asking you to do.
3. Put yourself in the situation and see if the way you are solving it makes sense.
4. It's okay to look for key words as long as you make sure that the operation(s) you are using makes sense within the problem.

Multiplication- What is so magical about the magic zero?
NBT5- Fluently multiply with multi-digit whole numbers using the standard algorithm.
Have you ever wondered why we use the "magic zero?" There's really nothing magical about it, except that it allows us to start in the tens place when we are multiplying the second digit in our problem! Check out the video below!!

Rounding Decimals on a number line
Take a look at this! In order to understand what rounding really means, we are rounding decimals on a number line. Check out the picture. Since we use a Base Ten system, our number line is divided into 10 parts. If we are rounding to the nearest whole, we want to see where our number lands closest. I always say "It's all about the Benjamins- think about money!" So if we rounded 4.2 to the nearest whole, we would only be 2 tenths away from 4 wholes and 8
tenths away from 5 wholes. Therefore, it would be closest to 4 wholes,
which we would round 4.2 to that number!
tenths away from 5 wholes. Therefore, it would be closest to 4 wholes,
which we would round 4.2 to that number!
Compare Decimals Chant
When you compare, you start at the left,
Look to the right, look to the right
Then stop, when the number is different, just compare
Look to the right, look to the right
Then stop, when the number is different, just compare
Decimals
We have gone head first into decimals the last week and a half! Have your child sing the few chants we have learned about decimal place value and patterns in multiplying and dividing decimals. It is a great way to remember what to do when you forget! We are continuing to work with decimals the next couple of weeks. We will be focusing on comparing and rounding decimals. We will continue to review the concepts we have learned. If your child is struggling, please send me an email or note. I am starting to pull guided math groups, so they should be receiving a little extra help there. Also, look in their math journal for notes, as this will help you help them at home. Thanks! :)
Number Sense Base Ten
Please look in their math journal for notes each day on how to solve our daily math problems. There are a bunch of examples to go by! Homefun should always match what we did during the day. :)
We have started the first unit in math- Number Sense Base Ten. The two standards we will be focusing on this week are:
NBT1- How a digit in one place represents 10 times as much, or 1/10 of another number.
NBT3- Read and write decimals.
