I created this graphing inequalities work mat when I taught Algebra 1 to help my students conceptualize what it actually meant to graph an inequality. So often, I have a tendency to just give my students a set of steps to follow without making sure they understand why we are following those steps. Why are …

# Dry Erase Activities

I created this Key Features of Functions Work Mat to use with my Algebra 2 students during our introductory functions unit. We used it to practice concepts including domain, range, increasing and decreasing intervals, positive and negative intervals, and x- and y-intercepts. I printed the Key Features of Functions Work Mats on 11 x 17 …

Here’s a third hidden equation puzzle from Erich Friedman. Circle one symbol in each column so that a true equation results reading from left to right. I love to use these hidden equation puzzles with dry erase pockets in my classroom. If you don’t have a classroom set of dry erase pockets, you could also …

I want to convince you why dividing polynomials using the box method is my favorite method for dividing polynomials. After taking a 2 year hiatus from teaching Algebra 2 to dabble in teaching physical science and chemistry, I’m back at it this year. One of the things I really missed about teaching Algebra 2 was …

This Evaluating Functions Spider Puzzle was the perfect practice activity for my Algebra 1 students. These spider puzzles are the creation of Andy Lutwyche, and they are a free download on TES. Andy has created spider puzzles for many other topics as well that are well worth checking out! I use these spider puzzles inside …

Before we started translating between words and algebraic expressions, equations, and inequalities, I decided to figure out what my students remembered about this process from previous math classes. I created a chart to be printed on 11 x 17 cardstock. I printed one chart for each table group. Then, I slid each sheet of cardstock …

I think I’m almost finally done sharing activities to review absolute value, opposite, reciprocal, and opposite reciprocal. This was a new skill addition this year, so I had to start from scratch with making review activities! To understand my rationale for this activity, you kinda need to know what my SBG quiz for this skill …

Last year, I learned about an activity called “Make a Million” from Julie Morgan who blogs at Fraction Fanatic. I tried this out with students several times throughout the year. It’s perfect for those awkward five minutes when you get through your lesson plan way faster than you expected. Kids LOVED it, but every time …

I created this printable Venn Diagram template to use with Guess My Rule cards, but it could be used in so many different ways in the math classroom. A couple of weeks ago, I was afraid that the lesson I had planned on Venn Diagrams wouldn’t take the entire 50 minute class period. I was …

Earlier this week, one of the science teachers I follow on Twitter retweeted an activity posted by AACT. The activity was called The Periodic Table of Mistakes. At first glance, it looks like a regular periodic table, but there are actually 25 mistakes hidden within the table. I right clicked on the image and selected …
