This Compound Inequalities Question Stack is a great self-checking activity to give your algebra students some much-needed practice with solving and graphing compound inequalities on a number line. I originally created this activity to use with my Algebra 1 students. If you are thinking to yourself that “Sarah hasn’t taught Algebra 1 in years,” you …

# One Variable Inequalities

I created these graphic organizers to give my Algebra 1 students some structured practice solving equations/inequalities with variables on both sides of the equal sign. We started out by gluing in a set of steps to our interactive notebooks. I created six practice problems for my students to work through together. This year I am …

I created these compound inequalities graphic organizers to give my Algebra 1 students practice solving compound inequalities. We completed these graphic organizers after our compound inequalities foldable. We only did four practice problems in our notebooks for compound inequalities. I think we should have done more. Here are close-ups of each: Free Download of Compound …

We did six practice problems in our notebook over solving equations/inequalities with variables on one side. Students stapled these problems together and glued them on a single page. Some students even chose to staple their paper with the steps on top of the practice problems to condense things even further. I kinda like this approach! …

This inequalities investigation was inspired by an activity from Discovering Algebra called “Toe the Line.” The goal of this activity is to remind students that we need to flip the inequality symbol whenever we multiply or divide both sides of the inequality by a negative number.

Recently, I wrote a blog post sharing a set of speed dating cards I created to review absolute value, opposite, reciprocal, and opposite reciprocal using printable business cards. I used the blank template I created to create a new set of speed dating cards for a different topic: graphing solutions on a number line. I’ve …

I created this one variable inequalities card sort activity for my Algebra 1 students to complete before we moved on to looking at two variable inequalities. Students are given five number lines and five equations/inequalities to match up. I created the number lines for this card sorts using GraphFree.com. I printed the card sort on …

I created this compound inequalities foldable to introduce the topic to my Algebra 1 students. We glued the resulting foldable in our interactive notebooks. I have NEVER been happy with how I’ve taught compound inequalities in the past. I’ve never really given my students as reason for why we need to even deal with compound …

On Friday, my Algebra 1 students started to review inequalities. It was so refreshing to see them realize that this was something they had studied last year in 8th grade. A few students mentioned that they had never figured out how to do these problems last year, and they asked lots of awesome questions. Including …

I want to highlight this one variable inequalities square puzzle shared by Public Schools of North Carolina in their Resources for Algebra Blackline Masters collection (page 1 of PDF). The file no longer exists online, but an archived version still exists due to the Internet Archive. These square puzzles are often known as “Tarsia puzzles.” …
