Assignment: Generate equivalent fractions with an area model

Answer both problems on paper. Then insert the two picures using the picture button in the text editor.  

Problem 1:  Use the area model to show why $\frac{3}{6}$ is equal to the same amount as $\frac{1}{2}$. Explain your answer using words and pictures. (You may use one or both rectangles to help explain your thinking.)

 Problem 2:  How many ninths does it take to make the same amount as $\frac{1}{3}$?  Explain your answer using words and pictures. (You may use one or both rectangles to help explain your thinking.)
