Reflection: Developing a Conceptual Understanding Evaluate expressions using substitution (Day 2 of 2) - Section 2: Play of the Day

 

In this task, students are pushed to agree or disagree with a statement, which I believe is a simple, concise, and relatively "Easy" way to ease students into writing about concepts that they are in the beginning stages of understanding deeply.  In this case, it pushes the understanding of the relationship between positive and negative numbers on a number line, as well as algebraic representations of this (for example, even though b does NOT have a negative sign on it, its value is negative, because it represents a negative value.)

 

Some students will use substitution to explain their work (substituting in actual values), while others will use a more abstract reasoning (e.g. a negative number subtract a positive number will always yield a more negative number).
