I’ve been a fan of this factoring puzzle for factoring quadratic trinomials since I worked through it at a Common Core workshop I attended (OGAP) in the summer of 2013. Over the last couple of days, I have been going back through these resources that I originally blogged about and giving each resource its own …

# Open Middle Tasks

I was shocked at first …

I’m here today to share a trig ratios puzzle with you. I’m currently using part of my summer to create some activities for my Pre-Calculus classes for this upcoming year. Last year, I felt like I definitely spent more of my time creating things for my Algebra 2 classes than my Pre-Calc classes. This was …

Two summers ago, I created some open middle style problems that have been a hit in my classroom. Both problems use a reusable set of tiles that have the numbers from -4 to +4 printed on them. These tiles are laminated which has helped them hold up to use over multiple years. The first problem …

After making my Function (or Not) Puzzle to give students practice classifying relations as a function or not a function, I was eager to make a similar open middle style activity to practice a different skill. I settled on creating an evaluating functions activity that would give students practice evaluating functions and hopefully help them …

I created this function vs not a function puzzle to help my students practice determining if a relation is a function or not a function. I also wanted my activity to perform double duty. I wanted students to be able to use the exact same activity to form relations that were functions and that were …
