Emergency sub plans for 2nd grade, no prep substitute math worksheets and a ready-made sub folder are all in this print and go Mini Mystery Detective math pack for second grade. Ten one-page detective cases cover adding within 20, two-digit addition and subtraction, place value, telling time, number lines, picture graphs, measuring length and equal shares, so a full morning of second grade math is ready the moment a teacher calls in sick. A sub plan page, an answers-at-a-glance sheet and a notes-for-the-teacher form come with it, so the adult in the room knows exactly what to do.
The morning a teacher wakes up sick is the one morning there is no time to plan, and these emergency sub plans are already written for whoever walks in. Every page explains its own math in the directions box, so the substitute hands it out and a second grade class gets straight on with it. Students match each answer to a suspect and cross that name off, so the pack marks itself.

When to Use This Resource
This is the pack that lives in the sub folder all year, written for the day nobody planned for. It holds up whether the substitute is a math specialist or has not taught second grade in years, and because each case is its own topic a teacher can pull a single page out any time one is needed. Use it for emergency sub plans and substitute folders, sub tubs, math centers, morning work, early finishers, homework, small group review, and back to school or end of year practice.
Grade Levels
Written for 2nd grade all year round, and useful for 3rd graders who need a confidence-building review at the start of the year.
