Advanced Food Fractions for First Grade Math

Video Transcript

Let's continue with our study of fractions. Over here. Now remember, the top number is the numerator, the bottom number is the denominator. The bottom number stands for how many parts the whole is broken up into, in this case, 2. And the top number is how many of those parts are we choosing. In this case, the whole is broken up into 3 parts, but we only want 2 of those 3 parts. Now, you can show this in your house with food. I've drawn food, you can draw food too. You can use real food too which is really fun. It helps your child understand real life situations. I think that's probably the most basic way that fractions are used to divide up food. So pizza works really great. You can draw a pizza just by drawing a circle with another circle slightly inside and then little dots to represent, make it look like pizza. And in this case, we have divided into 4 parts. If we were to write a fraction, 3/4, teach them how to say it, three-fourths. We would only choose 1, 2, 3 of these, so we would get rid of 1. And you can also use this to show how much of the pizza are we eating, we're eating three-fourths of it. How much of the pizza is already gone? One-fourth of the pizza is gone. And so with the same picture you can show me 2 different fractions. And you can continue with that down the road as you work on this to teach them how one-half of the pizza is also the same as two-fourths and it's not as confusing when you look at it like that. And of course you can break the pizza into eighths, or any other number, although a pizza looks weird broken into other numbers. And you can go on using other types of food in your house, slices of bread, and if you don't want to use food at all you can use the traditional shapes over here we have the square broken up into 1, 2, 3, 4, 5 even parts. That's our bottom number, how many of those parts are in blue? 2. How many of those parts are white? 3. And there we have our study of fractions. Make as many worksheets as you need, photocopy them or take out a lot of food. And that's it.
