Simplifying Expressions in Pre-Algebra

What are some common properties you can use to sort tiles?

• Weight and density

• Constants and variables

• Color and texture

• Shape and size

Why is it helpful to group tiles with positive and negative coefficients together?

• It makes the expression look more colorful

• It helps to avoid mistakes during simplification

• It makes the expression longer

• It changes the value of the expression

Why can't you combine unlike terms?

• Because they have different shapes

• Because they have different coefficients

• Because they represent different quantities

• Because they are not constants
