Using Technology in the Classroom for Mathematics

Hey Fellow Educators,

I am a third year 7-12 mathematics teacher in New York City wondering what other math teachers use in their classrooms to help in the engagement of their students.

For example, I use a smart board to for visuals and patterns, depending on the topic of mathematics.  I will use the interactive dice to discuss probability or show images that portray a recursive series.

I am just curious if other math teachers use it in different ways.
