Strive for equitable access to education, knowing your classroom will never be perfect.  However, don't obsess with trying to create equitable outcomes - no matter how much some in society and educational leadership push you to do so.  Equitable outcomes are both unrealistic AND undesirable.  Students are individuals with different backgrounds,  life experiences, interests, motivations, perspectives, goals, and abilities.  Lesson plans and academic units that are built primarily for "equity" inevitably fail most students because they don't effectively account for that individuality.
