This activity teaches the child the names of fractions up to tenths.
- "These are called fractions. The word fraction means to break apart."
- "This circle isn't broken apart. It is in one whole piece."
- "This circle is broken in two pieces."
- "With fractions, the pieces have to be the same size."
- "This circle is broken into three pieces that are all the same size."
- Teach the terms whole, half, and third. Do a three period lesson.

- Introduce the remaining fractions if the child shows interest, or do the rest at a later time.
