# Modeling - Hard Addition

Trixie was 3 years and 4 months at the time that this video was made.

**The Problem**

Suppose that I have 2 pennies. And suppose that you have 3 more pennies
than I have. How many pennies do you have?

**What To Look For
In This Video**

- Trixie doesn't seem to understand what it means that she has "3
more pennies than I have." She interprets it as meaning that
she has 3 pennies - not as 3
**additional**pennies. She cannot make a model.

Once again, I believe that the only sensible thing for me to do is to show her what I mean by working with her to make the model.
