Intro to Graphing Linear Inequalities in Two Variables
Help students confidently learn how to graph linear inequalities in two variables with this engaging and structured worksheet set! This resource guides students step-by-step through the key concepts needed to understand and graph inequalities on the coordinate plane. Students begin by comparing linear equations and inequalities, discovering the difference between a single line (a path) and a shaded solution region (an open field). They then practice identifying solution points, testing order

Order of Operations Algebra 1 -Activities, Notes, Practice, Maze, Quiz, Present
A complete, classroom-tested Order of Operations lesson that fixes the #1 PEMDAS misconception — that multiplication "beats" division and addition "beats" subtraction. Students learn the tied-operations, left-to-right rule through a "Calculator Court" error-analysis launch, then practice with leveled problems, a self-checking Crack-the-Code maze, and a quiz. Print PDF + editable PowerPoint, all keys included.Stop the "PEMDAS says multiply before divide" mistake for good.This lesson targets the e

Hi, I'm Isaac. 23 years in math classrooms — middle school, Algebra I, Algebra II, then back to Algebra I. Every resource here was built on a prep period, tested with real students.
Three years of middle school math gave me the foundation. Then Algebra I, then 14 years of Algebra II at a private high school (with a stretch of Geometry alongside). The past five years I've been back in Algebra I — both Honors and on-level. Every resource you'll find in this store came out of those Sunday-night prep periods: the tools I wished I had when I needed a unit test, a worksheet, a vocab activity, and a Friday game all by Monday morning.
What you'll find here:
Crack the Code puzzle bundles — self-checking worksheets in four formats (Riddle, Dialogue, Mystery Picture, Loop Cards). Engaging enough that students actually want to finish them.
Unit bundles (coming soon) — full pre-organized daily-practice packs for plug-and-play use.
Standalone activities — focused practice on specific topics, all TEKS and CCSS aligned.
Bonus with every purchase: free access to the live web app at themathtoolbox.com — 15+ classroom tools (Jeopardy, Kahoot, Escape Room, worksheet and test generators, and more) pulling from the same standards-aligned question bank used to build every product in this store.
What drives the work: find multiple ways to make math actually land for the students who think they're bad at it. A Friday puzzle that lets the kid who hates word problems get the right answer. An exit ticket short enough they finish it instead of giving up. Local and national teaching awards over the years, but those only matter here if they make the resources better for your students.
