Quiz Tuesday!

Dividing Decimals

Today we began dividing decimals...

Tonight's homework might be a bit challenging, but do your best and we will go over it tomorrow!

Long Division

Today we worked on Long Division!  Your parents will celebrate because this is how they learned to divide!  If you get stuck, ask them for help or watch the video below and read the notes from class!

Homework Problems:

Good luck and have fun!!!

Dividing Grasp!

Shopping Again!

Today's classwork (and tonight's homework if you didn't finish in class).

We also have a study guide due Thursday and a test Friday.  If you didn't get one today, I will give you one in class tomorrow!  Don't forget to get your report card envelope signed tonight!

Have a great night!

More Fraction Action and Decimal... uh... nothing rhymes... Action!

As we did on Friday, we spend more time working on converting fractions and decimals today.  We reviewed the various techniques and practiced independently too!  Tomorrow we are going to play a game with converting and continue to bring percentages into our work.  There is no homework tonight, but it wouldn't hurt to practice you math facts and long division...

Long division reminder HERE!


(Yes, I know that this is a strange video!)

Quiz Tomorrow!

Tomorrow we have a quiz on adding, subtracting, multiplying and dividing with decimals.  Today in class we reviewed what would be on the quiz and completed some practice problems to help us prepare.  See below for the examples and information.


There are 18 questions on the quiz.

2 adding, 2 subtracting problems.  These are basic.  Just add or subtract after lining up the decimals.

2 multiplying problems.  Again, these are basic.  Ignore the decimals when you multiply then count space after the decimal to determine where to place the decimal

2 estimating word problems.

example 1:

example 2:

2 buying items problems.

example:

1 word problem with numbers written in word form.

example:

2 word problems.  The math is basic, but you need to determine if we should add, subtract, multiply or divide.

example 1:

example 2:

example 3:

1 logic problem.  You will need to determine if a decimal is in the right place, if an answer seems reasonable, what answer should be expected, etc.  I can't give too much information about this one, but if you think about how reasonable an answer should be and feel comfortable doing basic estimation with decimals, you can do this problem.

2 division problems.  Just like tonight's homework.  See examples way below.

2 division word problems.

example:

Tonight's homework is to complete the Division worksheet and study for the quiz.  Since I want to give you as much time as possible on the quiz tomorrow, I am including the answers to tonight's homework just below.  Please correct your work at home if possible so that you can begin right away in class tomorrow!

Number 12 is a bit tricky and somewhat confusing.  Normally when we round things down, like in addition and multiplication, it makes our estimate smaller and therefore less than the actual answer.  But with subtraction and division, when we round down, it doesn't always do the same thing.  In this problem, rounding the divisor down means that each group is going to be a bit bigger, but since we rounded the dividend down by quite a bit, we were actually starting with much less.  By doing the actual math out, as I did below, we can see that this estimate is actually larger than the actual answer.  (By the way, I didn't finish the actual answer, but we can see enough to know that the actual answer is smaller.)  Tomorrow's quiz will not have a question like this, so please don't worry about it.  You should be able to estimate for examples like the ones provided up top.

Good luck studying!

Dividing Decimals

Today we were able to begin dividing decimal values.  Since we already have some practice with this topic, everyone seemed pretty comfortable dividing and solving these problems.

If you need a reminder check out the video below and take a look at the links to online notes.



Cool Math

Math is Fun

Tonight's homework is to complete the HW side of the paper I passed out it class.  I'm pretty sure that almost everyone finished during class!  If you want to keep practicing, please work on the opposite side of the paper and/or do the problems included on the note sheets passed out during class.

Best of luck and have a great weekend!  Remember, we will have a quiz on adding, subtracting, multiplying and dividing decimals on Tuesday!

Word Problem Workout!

I was extremely impressed by the work I saw in class today as we completed the fraction word problems.   I think we really met our object of determining which operation to use in real life situations to solve fraction problems.  Thank you for your hard work and effort on this topic.

I know that we got a little bit goofy when we were talking about dividing, but you should apply the same test when you try to complete a fraction division problem...  If you are about to chop up people into pieces, you very likely have the problem set up wrong or shouldn't be dividing.  Please take a look at the problems on you paper or at the completed examples from class below to help you think about it.

We  will have a test next Friday, October 19th, 2012, so start preparing.  I will give you a study guide and practice problems on Monday, but you should be reviewing your old homework, the extra practice papers I've given out, your notes and the previous blog posts to help you prepare for this test.  There's a lot of information on it, and the sooner you get started, the better off you will be!

There is No Homework, so just have a lovely weekend and try to fit in some review/studying if you can!

10/11/12

Today's date is cool.  But not cool enough to talk about for too long, so let's move on!  ;)

Tonight you have a lot of math homework.  I know I assigned a lot, but if you work carefully and use the pink paper, it should be manageable.  Remember, you need to do ten problems on each side of the multiplication and division sheets, 40 problems total!  We spent the majority of class working on the homework, so you should have made a major dent in your work if you worked diligently in class.  PLEASE remember to use the pink sheet to make the problems easier to compute.  Additionally, since you only have to do ten on a side, feel free to skip the harder ones.

A big multiplication table in case you forgot your pink paper at school:



Please work carefully and use the notes from earlier this week to help you if you are having any difficulty with  the homework.

Dividing Fractions

Today we began dividing fractions.  If you felt good about multiplying fractions, you should have no trouble dividing as long as you remember to

KEEP IT!

CHANGE IT!

FLIP IT!

Watch the video below for some practice and extra information.

This video doesn't include cross cancelling, but the division steps are clear.  He also helps with simplifying and converting to mixed numbers.


Another video:  He flips, changes and keeps in the opposite direction but still only flips the second fraction.


Below, please find the steps and examples from class:

 Examples from the notesheet.  Not assigned for homework, but good to use for practice if you need more!

Tonight's homework is to complete the dividing worksheet.  Good luck, work carefully!
