## WODB: Which One Doesn’t Belong?

Today, I just want to write a quick post about a #MTBoS resource that I hope everyone is already familiar with.  I used it a couple of weeks ago in my classroom, and the experience was such a fun, positive one! The resource is Which One Doesn’t Belong? The idea is that there are four …

## Modeling Exponential Growth and Decay Activity with Skittles

Today I’m sharing a creative way to use candy (in this case Skittles) for a modeling exponential growth and decay activity in Algebra. Last summer, I attended several weeks of workshops and conferences.  At the first workshop of the summer, I got to participate in an activity that used M&Ms to model exponential decay.  I …

## Modeling Function Machines with Flip Chutes Activity

Here’s a hands-on lesson I put together to teach my Algebra 1 students to evaluate and graph functions using function machines made of flip chutes. Let me set the stage so you can see where this falls in my Algebra 1 curriculum.  At this point in the year, my Algebra 1 kiddos have reviewed the …

## Russian Fable for Marriage Probability Activity

My statistics class recently worked through a probability activity involving a Russian fable regarding marriage from the MEP Demonstration Project. I’m gonna be honest.  My students and I have way too many conversations about my current relationship status.  I’m not married, and that bothers them.  Students have stopped me in the Wal-Mart parking lot to …

## Fly Activity for Graphing Ordered Pairs

I created this fly activity to introduce my students to the history of the coordinate plane and give them much-needed practice graphing ordered pairs. In college, I was always taught to begin my lesson plans with an anticipatory set.  I always struggled with these.  I couldn’t quite remember my teachers ever using them when I …

## Rational and Irrational Numbers Exploration Activity

This is a picture of a foldable that I created for my students to use as they walked through a rational and irrational numbers exploration activity.  This activity did not go as planned.  I thought it would take one class period.  After one class period, we had only started to scratch the surface.  I ended …

## Literal Equations Scavenger Hunt Activity

I realized I never wrote about the literal equations scavenger hunt activity I did with my Algebra 1 students for much-needed extra practice. During our unit on linear equation, my Algebra 1 students really struggled with converting equations from standard form to slope-intercept form.  So, I decided to save our unit on systems of equations …

## Guess the Age Activity for Introducing Absolute Value

Today I want to share a guess the age activity I used with my Algebra 1 students to introduce the concept of absolute value. Monday was my students’ first experience with absolute value in Algebra 1.  A few students who took Algebra 1 last year already knew what absolute value was.  A few others wrongly …

## Domain and Range Pictionary Activity

We started our Describing Graphs Unit in Algebra 2 by playing some domain and range pictionary. I used the domain and range graphing cards from Zero-Knowledge Proofs.  I gave each student two pages of cards to cut apart and keep in their notebook.  My students were surprisingly impressed by the small pocket we created to keep …

## Adding and Subtracting Polynomials Activity

Today I want to share an Adding and Subtracting Polynomials Activity I created for my Algebra 1 students. One of our objectives in Algebra 1 is that students will be able to add and subtract polynomials.  My students are usually pretty good about remembering to distribute the negative when the second polynomial is written in …
