Reflection: Real World Applications Fractional coefficients - Section 1: Warm-up

 

It's incredibly important to push application to real-world contexts, especially in the midst of a fairly "procedural" unit like solving equations.  What does it actually MEAN when we solve an equation like this?  I use the warm-ups each day - which I go over meticulously while the kids are fresh - to try to keep this at the forefront of students' minds.

 

That's why there are a series of application like algebra problems (like #2) that are important to make sure you go over in detail.  I like using these problems to model the commutative property (for example, if two kids write two different equations - 55 + 15x = 160 and 15x + 55 = 160 -- they are BOTH right! :)).

Fractional coefficients

Unit 2: SOLVING LINEAR EQUATIONS
Lesson 4 of 16

Objective: SWBAT solve equations with fractional coefficients.

Big Idea: Get kids to play matchmaker by matching up fractional coefficients with their perfect match... another fraction with whom they become 1. :)
