By embedding statistics, probability, and finance, while focusing on computational thinking, mathematical fluency, and solid understanding, Texas will lead the way in mathematics education and prepare all Texas students for the challenges they will face in the 21st century. The placement of the process standards at the beginning of the knowledge and skills listed for each grade and course is intentional. The process standards weave the other knowledge and skills together so that students may be successful problem solvers and use mathematics efficiently and effectively in daily life.
Expanded form decimals Video transcript Let's say I have the number So how could I expand this out? And what does this actually represent?
So let's just think about each of the place values here. The 9 right over here, this is in the hundreds place.
This literally represents nine hundreds. So we could rewrite that 9 as nine hundreds. Let me write it two ways. We could write it aswhich is the same thing as 9 times Now, there's a 0.
That's just going to represent zero tens. But zero tens is still just 0. So we don't have to really worry about that. It's not adding any value to our expression or to our number. Now we have this 5. This 5 is in the ones place. It literally represents five ones, or you could just say it represents 5.
Now, if we wanted to write it as five ones, we could say well, that's going to be 5 times 1. So far, we've representedplus 5 or 9 times plus 5 times 1.
And you might say hey, how do I know whether I should multiply or add first? Should I do this addition before I do this multiplication?
And I'll always remind you, order of operations. In this scenario, you would do your multiplication before you do your addition.
So you would multiply your 5 times 1 and your 9 times before adding these two things together. But let's move on. You have another 0. This 0 is in the tenths place. This is telling us the number of tenths we're going to have. This is zero tenths, so it's really not adding much, or it's not adding anything.
Now we go to the hundredths place. So this literally represents seven hundredths. And then finally, we go to the thousandths place. So we go to the thousandths place. And we have four thousandths. Notice this is coming from the hundreds place.
You have zero tens, but I'll write the tens place there just so you see it.
So it's zero tens, so I didn't even bother to write that down. Then you have your ones place. You have five ones.
Then you have zero tenths. So I didn't write that down. Then you have seven hundredths and then you have four thousandths.These Expanded Form with Decimals Worksheets are great for testing children on writing numbers out in expanded form that include decimals.
You may select 2 and 3 digit numbers with tenths, hundredths, or thousandths decimals. § Grade 3, Adopted (a) Introduction.
