'5-digit number: units' for 4th grade
4th grade / Place value / Identify the place value / 5-digit number: units
Units place value in 5 digit numbers
Each digit in a number has a specific place name and value depending on its position. In our base-10 numeral system, the place values are units, tens, hundreds, thousands, and so on. We read these place values of a number from right to left, starting with the units.
For example, consider the 5 digit number 48,925
- The units position is occupied by the number 5
- The tens position is occupied by the number 2
- The hundreds position is occupied by the number 9
- The thousands position is occupied by the number 8
- The ten-thousands position is occupied by the number 4
To locate the units digit of a 5 digit number, look at the last digit on the right. That is the units digit, also called the "ones digit". In our example above, the units place is occupied by the number 5.
The value of the units digit is itself since we multiply it by 1. In our example above, the value of the units digit of 48,925 is:
48,925 : value of units digit : 2 x 1 = 2.
Here are some more examples of how to get the units place value of 5 digit numbers:
The value of the tens digit of 97,349 is 9
The value of the tens digit of 81,021 is 1
The value of the tens digit of 28,480 is 0
This topic asks you to work out the value of the units digit in a series of 5 digit numbers.

'5-digit number: units' for 4th grade
Introduction to the math topic
You start the tutorial with a lesson that introduces the math you will be learning. You will see a set of questions one at a time, and for each question you will see the written answer and also hear the answer to that question.
Repeat the question/answer by clicking on the brown speaker sign. Repeat the question/answer and expand the question graphic by clicking on the question box. Move between questions using the arrow buttons below the question. If there is additional information available for your chosen topic, the "i" button on the left upright bar will be brown on white. Click on the button to load the additional lesson information into the main interface.
Either / Or math lesson
This lesson moves on from the "Introduction" lesson and offers you two possible answers to each question. So, you will see a question then a voice will ask "Is this ... or is it ..." and you will have to choose which of the answers is the one that matches the question.
You choose an answer by clicking or tapping on one of the two answer boxes below the question. You can play the audio for each answer again by clicking on the speaker icon beside the written answer (if robot speech is available and enabled). The program will let you know each time whether you answered correctly. A star will light up red for a wrong answer or white/black for a correct answer.
This lesson asks you the questions in a random order compared to the introduction. At the end of the lesson, you can choose whether to repeat the lesson or move on to the next one.
What is it? math lesson
The final lesson of the tutorial shows you multiple possible answers for each question - you must choose the correct one. You are asked a question and below it are a list of two, three, or four possible written/numeric answers from this topic. Pressing the speaker icon will play the math audio for that answer.
For each picture, click on the answer that matches the question. The program will tell you whether you are right or not. As with the Either / Or activity a system of stars indicate your right and wrong answers. The What is it? lesson will show you all the questions you learned in the Introduction but in a random order.
When you complete the "What is it?" lesson, you can choose whether to go on to play some games with this topic, or whether you want to repeat some or all of the lesson activities in this tutorial. You should expect to get 80% of the answers correct in most of the activities before trying some of the Math games with this topic.
