Lesson 7 Application Problem
Robert was snacking on a small container of applesauce. He ate half of the container. His mother and sister were upset he didn’t save much for them. So he split up the remaining applesauce into 2 bowls. Robert said, “I ate 1 half, and each of you got 1 half.” Is Robert right? Draw a picture to prove your answer.
What fraction of the apple sauce did his mother get?
Why can’t the container be partitioned into 3 equal parts?
What fraction of the applesauce did Robert’s sister eat?
Lesson 7 Concept Development
I have a beaker half full of liquid.
What fraction of liquid can you see? 1 half.
What about the part that is not full? Could that be a fraction, too? Why or why not?
It is a fraction because half is filled, and so it has 1 more half to be all
Even though parts might not be full or shaded, they are still part of the whole.
