### 1. Two More Fun Warm-ups Reviewing Word Problems

We have seen our 8th graders struggle with algebra problems that involve “the number of bills” and the “value of those bills”. They can write x + y = 27 if there are 27 five and 10 dollar bills altogether, but stumble over the *value* equation: 10x + 5y = 210 when told that the 27 bills add to a value of $210.

So we decided to try to start such distinctions earlier – 5th and 6th grade. Here are 2 Power-Point Warm-Ups that help students begin to make this journey. As always, use manipualtives (we used Cuisenaire rods and Monopoly money, but any blocks will do) and *give them time. *

### 2. Order of Operations Lesson

This is a more traditional lesson, since it represents a convention that mathematicians follow to avoid misunderstandings.

Since we are also 8th grade Algebra teachers, we insist on good algebraic form – what we call the “Sacred V”.
