Color Coding and Different Representation for Rounding

color coding for rounding adjusted (2)

 

There are two strategies used in this example for rounding.

The number line is a different representation for a rounding situation. In CRA this is the representational or pictorial level. Typically students are taught to round by looking only at the numbers which is purely symbolic.

The color coding helps the students discriminate between the number being rounded and the choices for rounding. As I’ve written previously, color coding helps a student discern different parts of a concept.
