Solving One-Step Equations

Inside the case file

Homework, morning work and a sub folder for the week before the break: five Easter CSI Mini Mystery Detective math case files on solving one step equations, 6th grade and 7th grade algebra. Students solve equations with one variable across the four operations on each crime sheet, then match the solution to a suspect and cross that name off until one is left, so algebra arrives as math worksheets and math activities in one no prep download. One step equations Easter work for March and April, then test prep, homework, morning work, sub plans and spiral review. No prep CSI math, with detective activities and full answer keys.

The week before the Easter break needs a lesson that runs on its own, and these one step equations cases do. Every solution a student finds takes one suspect off the lineup, so the class keeps going for the culprit rather than the grade. One case fills a period, and the answer keys are already behind each page.

The Cases

1. Missing Easter Eggs - every egg has disappeared
2. Easter Bunny Kidnapped - the Easter Bunny has been taken
3. Teachers Easter Chocolate - the whole stash has gone
4. Your Last Chocolate - somebody ate your last one
5. Easter Bunny’s Carrots - every carrot has gone missing

What's Inside

• Five case files, each with a crime sheet of equations and its own lineup of suspects
• One step equations with one variable, across adding, subtracting, multiplying and dividing
• Whole number solutions, so the algebra is the work and not the arithmetic
• Each answer matches one suspect and no other, so the page checks itself
• A full answer key for every case
• Print and go: no cutting, no laminating, nothing to prepare

What Is a CSI Mini Mystery Detective?

A CSI Mini Mystery Detective puts a crime, a lineup and a page of math in front of your class, and the only way to name the culprit is to get the math right. Each suspect carries a number, each solved question matches one of them, and that suspect is crossed off until a single name remains. Because a wrong solution eliminates the wrong person, these detective activities make students check their work in a way math worksheets cannot.

When to Use This Resource

The week before the Easter break is the hardest week of spring to teach, and this gives you real one step equation practice that a distracted class will still finish. It also works as the review before an equations test, because the five cases cover all four operations rather than drilling one. Solving the wrong way round crosses off the wrong suspect, so students spot the inverse they should have used.

It suits test prep, homework, math centers, morning work, early finishers, sub plans and homeschool lessons, with a class, a small group or one student alone.

Grade Levels

Written for 6th grade and 7th grade, where one step equations sit in the standards. Fifth graders take it as an introduction once inverse operations are taught, and 8th graders use it as a warm up before two step equations.

Why Teachers Love These Cases

• All four operations across the five cases, not one drilled five times
• Students catch a wrong inverse when the wrong suspect comes off
• No prep in the week before the break
• Works with a whole class, a small group, partners, or one student alone
