Application Problem

Anu needs to cut a piece of paper into 6 equal parts. Draw at least three pictures to show how Anu can cut her paper so that all the parts are equal.

What fraction of the whole is 1 part? 1 half. - Draw a line to show where you folded your paper.
- Write the name of the unit onto each equal part.
- Fold and label strips showing fourths and eighths to start, followed by thirds and sixths, and fifths and tenths.

Lesson 2 Problem Set Sample Solutions

- Circle the strips that are folded to make equal parts.
- There are _______ equal parts in all. _______ are shaded.

For the following problems, use your fraction strips as tools to help you. - Noah, Pedro, and Sharon want to share a whole candy bar fairly.
