Objective

SWBAT solve systems of equations modeling real-life situations (Day 5 of 5)

Big Idea

Get deep into algebraic thinking by solving problems that aren't so straightforward. A tricky one pushes kids to think algebraically.

Warm-up

10 minutes

Each day, students complete a Warmup that 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 challenges learners to demonstrate algebraic reasoning.
