SUB! How can we use the properties of algebra to figure out the intersection of two lines WITHOUT graphing? (Day 2 of 3)
Lesson 4 of 19
Objective: SWBAT solve systems of linear equations by substitution.
Each day, students complete a warm-up that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts. Today's warmup worksheet is WU63 Solve systems using substitution 2.

Play of the Day
Today's homework file (HW63 Solve systems using substitution day 2) contains 7 problem related to this lesson, as well as some spiraled review. I also give the kids the answers to the problems on page 2 of the assignment.
