2.1 Representing Integers

Section 2.1 — Representing Integers

Today we learned about representing integers using integer tiles.  Red tiles, or negative signs represent negative integers and yellow tiles or positive signs represent positive integers.  We looked at different ways to represent the same number using zero pairs. Finally we looked at vocabulary that helps us to know if an integer is positive or negative.

Below you will find both the section 2.1 teaching notes and answer key.
