  • Lets start out by reviewing what we already know… we know that we would count
  • To make a fraction, the object needs to be broken up into equal parts, meaning all the parts are the same size.
  • Fractions are written, with two numbers seperated by a fraction bar. The top number, which we call the numerator, is used to represent the number of partsthat we have. And the bottom number , which we call the denomonator is used to represent how many parts are in the whole.
  • Still confused??
  • Lets try writing one.. Taking a look at this hexagon.. How would we write a fraction to show only this much? Remembering what we just learned, fractions have a numerator and a denomenatorseperated by a fraction bar. We know we find the numerator by counting how many parts we have. 1 and we know the denomenator is the total number of parts, including the part you have. We can see this hexagon is divided into 6 equal parts to that means our denominator is 6. when we put it all together, this section is equal to one sixth of our hexagon.
  • Have the same value even though they may look different.... The rule to remember when dealing with equivalent fractions is that what you do to the top you have to do to the bottom.
  • Denominator numerator equivalent
