Reflection: Complex Tasks Solving Linear Systems of Equations with Substitution (Day 3 of 3) - Section 3: Guided Notes + Practice


It’s one thing to be able to plug some numbers into a formula or equation and solve. It’s even another to be able to identify those numbers from a word problem and do that. However, student understanding will not stick if a student cannot explain their reasoning or justification for WHY those numbers go where they belong in the equation or WHY this part of the equation requires a particular operation versus another. Reasoning and justification are some of the deepest levels of understanding when a student can demonstrate their abilities to do this. I push my students not to just tell me what I need to do or how but why I need to do it because then the application can become universal.
