Identify unit fractions
A unit fraction is the name given to a fraction where the numerator (the number on top) is 1.
So ½ is a unit fraction as is ⅐ and ⅛ but ⅖ is not because it's numerator is not 1, it is 2.
One reason unit fractions are interesting is because they are the reverse of the "integers" (that is, the whole numbers). When integers are written as fractions they are always the integer value over 1. So 2 is written 2/1 and 3 is written 3/1.
Another interesting fact is that if you multiply ½ by 2/1 you get 1, and this is always true when you multiply an integer as fraction by it's inverse unit fraction. If you think about it, it is quite intuitive: half of 2 is 1 and one third of three is 1, and a quarter of 4, etc., they are always 1.
Actually, you can expand that rule to say that any fraction multiplied by itself reversed will equal 1.
This topic asks you to identify unit fractions, but also fractions that can be simplified to unit fractions. To simplify a fraction, you divide both it's numerator and it's denominator by the same number. For instance, 3/9 (three ninths) can be simplified by dividing both numerator and denominator by 3 to give 1/3 (one third). Three ninths and one third are called equivalent fraction because of this, and if you think of three ninths of a number compared to one third of a number, you will see that the answer is the same.
With these interactive math lessons you will be learning "Identify unit fractions" from
3rd grade / Fractions in 3 easy steps. The math in our lessons consists of 6 questions that ask you to identify unit fractions and fractions that simplify to unit fractions.
There are 3 easy math lesson activities in this "Identify unit fractions" tutorial. These activities progress step by step to help you the learner gradually master this math topic. The activities are based on "3 stage questioning", a method of learning that quickly and easily builds your confidence as you work through the short series of lessons that strengthen your knowledge of the math that you want to learn.
When you have completed the tutorial for a topic, you should try some of our games before finally doing the test for your chosen topic. See the Help box below for detailed instructions on how to use the lesson activities to help you learn your math more easily.

'Identify unit fractions' for 3rd 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.
