Teaching with Algebra Tiles: Axioms, Expressions and Equality


In this course we will take a journey through directed number arithmetic to culminate in working algebraically. We will take an axiomatically coherent approach using algebra tiles as our model of communication. In doing so, we offer pupils the opportunity to gain conceptual appreciation and see connections between ideas that are the fundamental building blocks in mathematics.

Contents

Axioms and Expressions

In this section, we will introduce algebra tiles and explore the models we can use in our instruction to communicate addition, subtraction, multiplication, and division with integers. Plus, we will extend into algebra and explore how we can use algebra tiles to simplify expressions.
