This editable document can be used as a practice station, quiz, guided work, etc. Easily accommodate varying levels of mastery by including/deleting some or all of the supported thinking boxes.
For students who need a lot of facilitation, keep all written supports but allow them to feel an independence by not calling over for teacher support for each question. For students that have mastered this line of thinking, remove all of the supports. Any students who are in the "getting there category" could try using the support for one question and then translate that formatted thinking to the other like questions.
14 questions cover expressions, balances, pattern tables with a constant, and understanding the concept of a variable. Answer key included.
