00:00This video is part of a Google Form quiz that teachers can assign to their students for
00:05homework. After the students submit their answers, then they can play a video like
00:09this one to see the answer explained. We've made more than 100 quizzes as Google Forms
00:15with free access videos, which teachers are welcome to copy for free. To get access to these,
00:21please see the link in the description. This video is based on a question from an
00:26actual state exam. You may have one like this on your state exam. If you've not already watched the
00:31videos on Word Form Part 1, Word Form Part 2, and the Rounding Rainbow, then we suggest that you view
00:38those before watching this video. What is 25 and 4,397 ten-thousands written as in numeral?
00:47Enter your answer in the box. For problems about place values, we recommend that you first draw the
00:54rounding rainbow. Let's start by writing the decimal point and drawing a dashed line.
00:59We'll write in the ones place above the dashed line. Then, we'll draw 5 dashed lines on the left
01:05and 5 on the right. Each dashed line will be a place value. Then, we draw in the arches that connect
01:11the matching place values on each side. Now, we write the name of the place values for each arch.
01:17And finally, we write a reminder that those on the right side of the decimal
01:21have a suffix that says THS. We call this the rounding rainbow. We'll be using it a lot when
01:27we round numbers. Now that all the place values are labeled, we're ready to answer the question.
01:33The word AND means the decimal point. The number before the word AND is the part that goes on the
01:40left side of the decimal point. The number after the word AND is the part that goes on the right side
01:46of the decimal point. In this problem, the word 25 goes on the left of the decimal point.
01:52We'll write it in numerals here. The phrase 4,397 ten-thousandths is the part of the number
01:59that goes on the right of the decimal. We circle the word that ends in the suffix THS. This word
02:05tells us the place value where the digit ends. We look at the word or words that are immediately to
02:11the left of the word with the THS suffix. In this case, the words are 4,397. We write this as a
02:20numeral here. The word with the THS tells us where this numeral must end. In this case,
02:26it's the ten-thousandths place value. That means the 7 will be in the ten-thousandths place value.
02:32Let's return to the rounding rainbow. We'll write the numeral 25 here for now. We can write the 25 to
02:38the left of the decimal point. 25 is a small number, and we're familiar with how to write it.
02:44Next, we need to write the correct digits on the right side of the decimal.
02:47Let's return to the question. Here's the numeral 4,397. That's the numeral we'll be writing on the
02:53right side of the decimal place. We have to make sure that the end of this numeral, which is the
02:58digit 7, goes in the ten-thousandths place. Now let's return to the rounding rainbow. We write this as a
03:05numeral here. We'll circle the place value for the ten-thousandths, which is where this numeral ends.
03:11We'll write the numeral. Please note how the 7 is in the ten-thousandths place value.
03:16This is the numeral way of writing 25 and 4,397 ten-thousandths. We'll write this number inside the box.
03:25Thanks for your attention.
