Finding Parts of a Whole
Students will need to be able to determine fractions of a whole number or whole group of materials. It is important to understand that the fraction of the whole is also a whole number and not a fraction. For example, one half of ten students is five students. Not five tenths students. The video on how to find parts of a whole is provided below. Click on the play button to view the video. There is a link to practice problems below the video and some word problems are provided at the bottom of the page that demonstrate what the students will ultimately have to do with the skill.

Sample Word Problems:
1. Jia is making spaghetti and meatballs. She uses 5/12 of two dozen eggs to make it. How many eggs did Jia use?
2. Jordan owns an ice cream shop. He has 54 tubs of ice cream in the freezer. 2/9 of the tubs are vanilla. How many tubs are vanilla? How many tubs are not vanilla?
3. At the park, 4/7 of the children are boys. There are 21 children at the park. How many girls are at the park?
4. The local pet store has 35 pets. 2/7 of them are dogs. 1/5 of them are cats. How many of the pets are neither dogs nor cats?
5. In a group of children, 2/5 of the children wear glasses. If 10 children wear glasses, how many children do not wear glasses? (Warning: This one is tricky! Really think about what it is asking.)
