# Modeling - Easy Addition

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

**The Problem**

Trixie knows that her school-age cousins get homework - worksheets with
math problems.
So Trixie wants "homework" also. Click here
for a copy
of her worksheet "homework."

**What To Look For
In This Video**

- The worksheet provides the basis for a conversation. That conversation begins with the first problem. "There are 3 circles and 4 triangles. How many circles and triangles are there altogether?"
- Trixie clearly understands this
Easy Addition problem. She easily counts the 3 circles and the 4
squares. More importantly,
she now knows what it means to "count the circles and squares
**altogether**." - Given that Trixie already know how to model Easy Addition, I am
using this worksheet
to
**introduce equations**as representatives of word problems. In this case, Trixie is introduced to the equation "3 + 4 = 7." And she is also learning that that equation is read "three plus four makes seven." - A second purpose is to give Trixie
**practice**with Easy Addition - through this kind of practice she will eventually begin to remember some simple combinations and discover other shortcuts. - And a third purpose is to help her
**learn to write the numerals**.
