Student Work is Coming Soon Poster

Usually, I'm a big fan of decorating my bulletin boards. Hello, I have an entire page on my blog dedicated to bulletin board designs. This year, after moving classrooms for the second time in two years, I decided to take a different approach to bulletin boards.

I still decorated the walls around my bulletin boards, but I chose to keep the bulletin boards clean and reserved for student work. My thought behind this was that I have lots of energy to decorate before school starts. After school starts, that energy is devoted elsewhere. So, if I want to make a habit of displaying student work in my classroom, I need to make it as easy as possible. Otherwise, it won't happen!

In this photo, you can see my two bulletin boards. I had several others in my first classroom, but my new classroom didn't have enough wall space. My husband ended up using them in his classroom. 

To keep my bulletin boards from looking bare and un-decorated, I made a poster to hang on each bulletin board.

I am proud to say that the first poster came down last week. So, they'll soon be a blog post to share the new bulletin board. :)

Want a copy of the poster for your own bulletin board? You can download it here.

Monday Must Reads: Volume 11

It's time for another Monday Must Reads! Thankfully, it's a much less hectic Monday than last week due to the fact that the Oklahoma Teacher of the Year Ceremony has come and gone. In case you missed it on Twitter, I didn't win. And, I'm completely okay with that. The winner is a fantastic and inspiring lady, and I'm certain she is perfect for the job of OK ToY! I'm 100% at home in the classroom (the same cannot be said for giving speeches on a stage!), and I'm super excited that I will get to continue teaching in the classroom next year. Otherwise, how would I come up with ideas to blog about?!?

Mrs. Riley shares a graphic with different division-related vocabulary. For the past few years, I've taught my students about the word "vinculum." But, "obelus" and "virgule" are new to me!

For the second year in a row, I have had my math concepts students make mobiles using construction paper and stickers. When I shared a picture of this year's mobiles, Andrew Gael shared his own project he does with students that definitely knocked my socks off. Andrew has his students make different shapes, fill the different shapes with different numbers of beans, and create an actual mobile! I. Am. Impressed.

Mr. Fredericks put a twist on the classic line-up structure. Students had to put themselves in order according to their guesses without talking!

Image Source:
David Butler comes up with the coolest activities for his weekly 100 Factorial events! I've seen the four color theorem plenty of times before. But, I've never seen it turned into a competitive game!

Image Source:
David also created a very interesting problem called "Zero Zeros" that I need to spend some time thinking about!

Need to teach piecewise functions? Susan Russo has you covered with an awesome real-life scenario to motivate your graphing. Krispy Kreme Doughnuts!

Kathryn Kubena has a way of appealing to your sweet tooth and making you wish you taught geometry all at the same time. The idea of using marshmallows as points and candy corn as arrows is BRILLIANT.

Image Source:
Rick Barlow gets his students up and moving around the classroom while practicing their vocabulary. I love everything there is to love about his vocabulary party idea! Can't wait to try this in my own classroom! Check out his blog post here with more details!

Image Source:
Need to teach the difference between discrete and continuous? Meredith Purser had the great idea to bring some props to class!

Image Source:
Laura Vogel brings graphing data to life by having her students GROW their own data. Yes, I want to be that kind of teacher! #teachergoals

Years ago, I blogged about using fast food combo meals to teach the distributive property. Stephanie Goldberg took it up a FEW notches by having her students build their own combo meals with the most adorable stickers I have ever seen.

Joe Cossette shares posters of three actionable norms he plans on implementing in his classroom this year. I think we should all aspire to follow these in our own classrooms.

 Until next week's post, keep sharing your classroom awesomeness!

Free Scientific Method Posters from Scholastic

At the beginning of my career, I ran across a set of free scientific method posters from Scholastic. I remember thinking to myself, "These are so cute. I almost wish I was a science teacher!"

Fast forward a few years. I'm now teaching chemistry after teaching physical science last year. This means I can finally hang them up in my classroom!

I thought the posters were missing something, so I whipped up a "Scientific Method" header to hang on top. You can download my file for this scientific method header poster here.

Eventually I will get around to sharing pictures of all the posters in my new classroom!

Question Stack Explanation Card

I'm currently in the process of making more question stacks for my Algebra 1 classes. Every year, students are a bit confused when I introduce the practice structure. Often, they are talking or day dreaming when I am giving the crucial instructions, and they end up wasting a lot of time.

This year, I've decided to make a template for students to use with their question stack cards that has the instructions printed on it.

Here's what I've come up with:

I've printed them on peach paper and laminated them.

You can download the file here.

Want to see the question stacks I have created thus far and posted on my blog?
Factoring Trinomials
Rationalizing the Denominator
Adding and Subtracting Polynomials in Function Notation
Operations with Radicals
Evaluating Expressions

How Many Elements Can You Name?

Just a quick post today to share a quiz I recently wrote for my chemistry class. It's a quiz to see how many of the elements they already know before we delve into our study of the periodic table.

I don't expect my students to be able to name all 118 elements. Hello, I can't even do that myself! But, I do want to emphasize to my students that there are 118 elements. The numbers are there only for students to keep track of how many they can remember. They do not need to know the atomic number for each element and place it correctly. Though, maybe the quiz could be used for this later in the year???

War Activity for Practicing Absolute Value, Opposite, Reciprocal, and Opposite Reciprocal

I might have went a bit crazy when I started making activities for our first skill of the year in Algebra 1. So, you'll have to put up with quite a few posts involving activities for practicing absolute value, opposite, reciprocal, and opposite reciprocal.

Today, I want to share a war activity I created. My sister and I loved playing war when we were kids. Most games weren't that exciting. Whoever had the most aces almost always won. But, there was just something exciting about throwing down a card to see whose card had the highest value.

While the traditional card game is only played with two people, this practice activity can work with two, three, or even four students in a group. Each group gets a set of cards. The cards are printed on two different colors of paper and laminated.

The yellow cards are criteria cards. There are fifteen cards. Three each of five types: original number, absolute value, opposite, reciprocal, and opposite reciprocal.

The criteria cards get shuffled and placed in the center of the playing area. The rest of the cards are distributed evenly according to the number of players.

The top card on the deck of criteria cards is turned over. This card tells the players how the winner will be decided. The player whose original number is the greatest will win. Original number is the easiest because students don't have to do anything to their numbers to determine the winner.

Each player turns over the top card on their deck.

8 is the highest original number, so the other two players give their cards to the player who had 8. These cards are placed on the bottom of the winner's stack.

Now, let's change the criteria card and flip over some new numbers. This time, students have to find the opposite reciprocal of their numbers.

1/3's opposite reciprocal is negative while the others are positive, so that player doesn't win. 1/3 > 1/8, so the face-up cards are given to the player with -3.

Up next: Opposite

The opposite of -7 is 7 which is the highest value of any of the opposites (7, 6, 1/4).

Next Round: Absolute Value

My students really enjoyed this game! They had quite a bit of trouble comparing fractions to determine which was larger. I spent a lot of time going around and helping students figure out which values were bigger when fractions were involved. This is something they should have mastered in middle school, but we'll just have to keep practicing comparing numbers until they get it!

Here are a few action shots:

Add Em Up Activity for Non-Standard Operations

Non-standard operations are one of the skills that are in the new Oklahoma standards that weren't in the old standards. So, I need to work on building up activities for this topic. I decided to create an Add Em Up activity to give my students practice with these weird looking problems.

Students are given four problems. When all four problems are complete, the sum of the four answers should match the number in the center. This allows students to check their work. If their sum doesn't match, it's time for them to start rechecking their work!

You can give all four problems to one student, or you can give the set of four problems to a group and have each student do one of the problems. Either way works! I prefer to have each student do all four problems myself.

Here are the two problem sets I created:
