Hey, guys, it's been brothers.
- 00:02 - 00:04
We are back for a brand new unit of math.
- 00:05 - 00:07
It is math unit.
- 00:07 - 00:10
Fourth, and let's go ahead and get started.
- 00:10 - 00:13
This is our opening unit, the opening of our unit.
- 00:14 - 00:16
So of course, we're going to do goals and definitions.
- 00:17 - 00:19
That's what this unit is.
- 00:19 - 00:21
This the beginning of this unit is all about.
- 00:21 - 00:23
The first day is all about goals and definitions.
- 00:24 - 00:34
So math unit four, we will start with goals.
- 00:34 - 00:36
There are four goals for this unit.
- 00:36 - 00:39
And, um, you should have your notebook out and you
- 00:39 - 00:41
should be writing these things down.
- 00:42 - 00:44
And at the end, I will show you my notebook
- 00:44 - 00:46
so that you can see that yours looks like mine.
- 00:49 - 00:52
The first goal is five in 1.1.
- 00:53 - 00:58
I can estimate solutions to division problems.
- 00:59 - 01:02
You know that to estimate means to make an educated
- 01:02 - 01:07
guess. The solution is the answer to the problem.
- 01:07 - 01:10
So you're saying I can guess and make an educated
- 01:11 - 01:14
guess for the answer to division problems.
- 01:14 - 01:17
So, as you can see already, this unit is about
- 01:18 - 01:21
division. Yes.
- 01:22 - 01:27
Our second goal, five in 1.2 is I can divide
- 01:28 - 01:32
multi digit numbers by one and to devise Er's.
- 01:32 - 01:35
So we started division in fourth grade, moving to fifth
- 01:35 - 01:39
grade. Now we are expanding how many numbers we are
- 01:40 - 01:42
dividing, so we're not only dividing by one, but we're
- 01:42 - 01:45
dividing by two digit divided divisor xcx.
- 01:50 - 01:52
The next goal is five in 1.3.
- 01:53 - 01:56
Remember, you can pause this at any time so you
- 01:56 - 01:59
can make sure you're writing down the goal.
- 01:59 - 02:05
I can recognize that quotients can be represented in different
- 02:05 - 02:09
ways. The quotient is the answer to a division problem.
- 02:10 - 02:13
So what we're saying is that the answer to the
- 02:13 - 02:18
division problem can be written down or or represented in
- 02:18 - 02:19
a different way.
- 02:19 - 02:21
It doesn't have to be done one way.
- 02:21 - 02:23
It's going to be done more than one way, at
- 02:23 - 02:27
least three, and you'll be able to see that as
- 02:27 - 02:28
we go alone.
- 02:29 - 02:29
Thank you.
- 02:32 - 02:35
The last goal for this unit is I can solve
- 02:36 - 02:41
real world problems requiring addition, subtraction, multiplication and division off
- 02:41 - 02:42
multi digit whole numbers.
- 02:43 - 02:45
Um, so, of course, that's word problems.
- 02:46 - 02:49
We're talking about being able to use word problems with
- 02:49 - 02:49
different steps.
- 02:49 - 02:52
It's not just going to be multiplication or not, just
- 02:52 - 02:54
division, but you might have to add or subtract first
- 02:55 - 02:56
and then multiply or vice versa.
- 02:57 - 03:00
We're gonna be using all four of those orders of
- 03:01 - 03:05
all those operations in orderto answer the word problems.
- 03:10 - 03:12
Now that the goals are done, we're going to go
- 03:12 - 03:13
into the vocabulary.
- 03:14 - 03:16
There are three vocabulary words for this lesson.
- 03:21 - 03:24
The first vocabulary word is the inverse operation.
- 03:25 - 03:28
The inverse operation is the opposite operation.
- 03:29 - 03:32
So the inverse of addition is subtraction.
- 03:33 - 03:36
The inverse of multiplication is division.
- 03:45 - 03:47
The next word in our vocabulary is quotient.
- 03:48 - 03:51
The quotient is the answer to a division problem.
- 03:53 - 03:57
This is a review word because we as started division
- 03:58 - 04:00
last year, so we know that the question is the
- 04:00 - 04:01
answer to a division problem.
- 04:01 - 04:03
But we just wanna make sure you all remember.
- 04:04 - 04:08
And then the last word in the vocabulary is product,
- 04:09 - 04:12
and the product is the answer to a multiplication problem.
- 04:15 - 04:19
So, um, we again know that this is a review
- 04:19 - 04:23
word. It is the word that we've already unknown, but
- 04:23 - 04:24
we have to review it.
- 04:25 - 04:30
Um, and now the next lesson, which will be our
- 04:31 - 04:36
unit unit for lesson one, we'll begin with multiplication because
- 04:37 - 04:39
we know that you can't divide unless you multiply.
- 04:45 - 04:48
Now I'm going to flip my camera over so you're
- 04:49 - 04:52
able to see my notes to make sure that your
- 04:52 - 04:53
notes look like mine.
- 04:57 - 05:02
So I have uniforms at the top, my goals and
- 05:02 - 05:06
then all four goals written that, um, I just showed
- 05:06 - 05:11
you. And then the vocabulary words There are three vocabulary
- 05:12 - 05:14
words again, just like I showed you.
- 05:16 - 05:19
And that should be the page that is in your
- 05:19 - 05:25
note in your notebook, if you need to.
- 05:26 - 05:29
You could just pause it right here and make sure
- 05:29 - 05:30
you write everything down.
- 05:30 - 05:32
Or you can go back and check and make sure
- 05:33 - 05:33
you do it.
- 05:33 - 05:33
Either way.
- 05:34 - 05:35
It's just fine with me.
- 05:37 - 05:39
Alright, guys, I will talk to you soon.
- 05:40 - 05:41
I hope you had a great math lesson.
- 05:41 - 05:43
Hope you got all these notes written down by
