Attached are 2 warm ups for Systems of Equations using the Substitution Method.
I used these in class on day 1 and day 2 of teaching the substitution method. Day 1 is meant to introduce the concept based on prior knowledge, and day 2 is meant to build off of the substitution method lesson from the previous day. This is displayed on my whiteboard as students walk in the classroom and they are given five minutes to complete the problem. After that, we go over the warm up and answer any questions the students have regarding the substitution method. Answer key is included. Enjoy!
