{"product_id":"two-step-equations-mystery-detective","title":"Two-Step Equations | Mystery Detective Worksheets | Grades 5–8 | Smuggler","description":"\u003cp\u003eTwo step equations practice for 7th grade math, with ten Mini Mystery Detective cases on solving equations of the form px + q = r and p(x + q) = r. It's 7.EE.B.4a work that uses integers, negative numbers and decimals, and the smuggling ring theme suits middle school. Use the worksheets as warm-ups, in math centers or for homework during your expressions and equations unit. There's no prep, and every case has an answer key.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCases 1 to 4 have no parentheses. They start with positive answers, then bring in negative numbers, negative coefficients and decimal coefficients. Cases 5 to 7 move on to equations with parentheses, and the last three cases mix both kinds. Students find each answer on the suspect list and cross that name off. If every answer is right, one suspect is left at the end, and that's the villain.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10 one-page cases with 20 two-step equations each, and an answer key for every case\u003c\/li\u003e\n  \u003cli\u003eEquations written both ways around, like 7t − 34 = 344 and 168 = −3(k − 36)\u003c\/li\u003e\n  \u003cli\u003eEvery answer is a whole number.

The cases get harder in the order they're numbered, which means you can hand them out as the unit goes along. Cases 8 to 10 mix both forms of equation, and they make a solid review before a unit test. The pack also works for small groups, sub days, early finishers and state test prep. 8th grade teachers can use it to review equations at the start of the year.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMade for 7th grade (7.EE.B.4a).
