I got to use a break out lesson for my observation this year to teach factoring trinomials when a=1. It was an exploration lesson and it was SO fun!

# The gist of the lesson was this:

~I reviewed FOILing

~I explained that we were now going backward

~I gave them examples of FOILing step by step and told them that they needed to figure out the numbers that were being used to break apart the polynomial

~Each group had four questions after they factored each question they had a puzzle to solve

~Each answer for each problem had a different puzzle and would lead them to a number on their lock (or direction, or letter, or a room number, depending on the lock)

# Grouping

1. High-level group: This group I wanted to challenge so I gave them a few trinomials where a>1.

2. Medium-level: These were my run of the mill kids! Together we can! And they did!One group had all x2-bx+c and the other x2+bx-c.

3. Medium-level: These were my run of the mill kids! Together we can! And they did!One group had all x2-bx+c and the other x2+bx-c.

4. Medium-low-level: This group only had three problems. Their lock only had three digits. I also put students in this group that struggle a bit, but with time they can get it. All three problems were x2-bx-c.

5. Low-level group: This group had problems with all positive coefficients and constants so they wouldn’t have to mess with adding and subtracting integers. I wanted them to experience some success.

# Locks

### Directional Lock – Students used a digit of their answer, found it around the room, used a black light to find a direction (written in invisible ink) that they used on their lock.

### 4-Letter word lock– Students used their answer and added digits and found a certain letter from the alphabet to spell out a word. Very important that you choose a word that the lock spells. Don’t choose a word and figure out the lock doesn’t have that word.

### 4-digit lock– Just had the students solve the puzzle then made the answers match a number on the lock.

### 3-digit lock– Same as 4 digit.

### Key Lock– The numbers that the students got sent them to a room where they got the key from one of my teacher-besties.

Other Resources to Complete the kit!

A bundle of locks- Cheaper than buying each sperate lock or if you want extras.

Hasp- Useed to clamp onto the box and all the locks clamp onto it.

Box- I put a bunch of candy in the box that of course was locked.

I tailored my answers to fit my locks. I would get an answer and add things to it or choose an element from it that when with my lock. So really I could use any problems I wanted, make up random answers and reset the locks to match the numbers I got!

Is there a pdf of the full breakout anywhere?
