Today we are going to begin working with fractions. Fractions are parts of a whole. Think of it this way. If you order a whole pizza, it comes cut into slices. Each slice is part of the whole pizza. If you get a small pizza that is cut into slices, each slice is 1/4 of a pizza. The number on the bottom tells me how many slices the pizza was cut into. The number on the top tells me how many of the four slices.
There is one important difference between fractions and pizza slices. Usually, pizza slices are different sizes. Some are bigger and some are smaller. With fractions, each slice has to be the exact same size.
Here are some videos to help you understand.
