00:00Hey kids! I am the number one and I am riding one of my dragons. Today I am going to learn
00:07about fractions. I already know a little but it has been a while so can you help me learn
00:13about fractions? Great! Thank you for your help. Let's go learn about fractions.
00:24Here we have a circle and this represents one whole. We have one whole circle. A fraction
00:36represents parts of a whole. So if I divided this circle into four parts, each of these
00:42parts are a fraction of the whole circle. We can see fractions in several ways like
00:48with pictures or numbers. You might remember what the fractions look like. Here we have
00:56a fraction that is one fourth. In a fraction the top number is the numerator and the bottom
01:04number is the denominator. We have four parts to this circle and that is why the denominator
01:12shows four because it shows all the parts of the whole circle. One part of the circle
01:19is now colored green. The numerator shows the one green part which is a part of the
01:24whole circle. So this fraction shows that one of the four parts is green. Now that we
01:30have refreshed our minds let's look at fractions in equations. Now we are going to learn more
01:38about how fractions represent the parts to a whole. We will do this by building equations
01:44to match the pictures. We have a circle here that is divided into equal parts. Can you
01:49tell me how many parts there are? Correct! There are three parts to the whole circle.
01:57So to make a fraction out of this circle, what will the denominator be? Correct again!
02:06The denominator will be three since there are three parts that make up the whole circle.
02:11Now that we have the denominator let's find out how many parts of the circle are pink.
02:16Well we just have one part that is pink so we put a one in the numerator. We just made
02:22a fraction that shows how many parts are pink. One third of the circle is pink. Awesome job!
02:31We are now going to create an equation by adding the fraction of the blue parts of the
02:35circle with the fraction of the pink part of the circle. What is the denominator for
02:39the blue parts of the circle? The answer is three because the denominator is always the
02:47total amount of parts that make up the whole and there are three parts. Now to get the
02:53numerator we need to count how many blue parts there are. There are two blue parts of the
02:58circle. So we can now say that two thirds of the circle is blue. Great job! So what
03:07happens when we add the fractions together? You may have not learned this yet but you
03:12will soon. When we add the two fractions together we get the whole shape. We get three parts
03:20out of three parts or one whole. The numerators got added together and the denominator stayed
03:25the same. This stuff is awesome! I wish I had more time to go over more but I've got
03:34to get going. Join me next time. We'll see you later. Goodbye!
