Challenge your 7th graders to think strategically and flex their integer operation skills with Expression Maker: Integer Operations Puzzles! This engaging math puzzle set includes eight progressively challenging task cards where students fill in missing numbers to create true expressions using addition, subtraction, multiplication, and division. Each puzzle features a Number Bank and specific goals—similar to an “Open Middle” problem format.

Designed to deepen conceptual understanding and procedural fluency, this activity helps students master integers operations while promoting mathematical reasoning and collaboration. As learners experiment, test, and revise their expressions, they build critical thinking skills and perseverance—key elements of Building Thinking Classrooms. Whether used as a lesson, station rotation, or enrichment task, Expression Maker makes integer operations meaningful, engaging, and discussion-rich—helping every student grow in confidence and accuracy.
