Inside the case file
5th grade math review worksheets covering adding, subtracting and multiplying decimals, long division with two-digit divisors, powers of ten and metric conversions, adding and subtracting unlike denominators, multiplying fractions, order of operations with brackets, volume of rectangular prisms, line plots and the coordinate plane are all included in this no-prep Mini Mystery Detective pack. Ten one-page detective cases cover a whole year of grade 5 math, one topic per page, so you can use them in any order as back to school review, a beginning of the year assessment for rising 6th graders, end of year review, math centers, morning work, early finishers, sub plans, homework or small group intervention. Use it as a spiral review in the first weeks back, as cumulative practice before a test, or as an end-of-year wrap-up — the ten topics stand alone, so you can hand out one case a day or the whole pack at once. Completely no prep, just print and go.
What's Inside
- Decimal operations: adding, subtracting and multiplying to hundredths, set out with the decimal points lined up
- Long division: four-digit dividends and two-digit divisors, written under the division bracket
- Powers of ten and metric conversions: multiplying and dividing by 10, 100 and 1000, kilograms to grams, milliliters to liters, and rounding decimals to the nearest tenth and hundredth
- Order of operations: parentheses and brackets, including expressions with two levels of grouping
- Adding and subtracting unlike denominators: two bars cut into different sized pieces, answers in simplest form
- Multiplying fractions: an area model shaded both ways, so students see why the product is smaller than either fraction
- Volume of rectangular prisms: counting unit cubes on the small crates and multiplying length by width by height on the large ones
- Coordinate plane: two number patterns graphed as ordered pairs in the first quadrant, then continued past the last plotted point
- Plotting figures on a grid: read the corners off the axes and find the area in square units
- Line plots with quarter inches: how many days, and how much rain, read straight off the plot
- A red-inked answer key for every single case
Ten separate cases, each one a single page with a matching answer key. Every page covers a different fifth grade math topic.
What is a Mini Mystery Detective?
A Mystery Detective is a print-and-solve detective activity: an escape room without the locks. Each page sets up a case with a line-up of suspects, and every suspect wears a number on an ID badge. Students solve the problems, cross off the suspect whose badge matches each answer, and the one suspect still standing is the villain.
Because every correct answer eliminates exactly one suspect, the page checks itself. Students know straight away if something has gone wrong, and they will go back and find their own mistake to catch the culprit.

Grade Levels
Designed for 5th grade and for 6th graders reviewing fifth grade skills at the start of the year. Also beneficial for struggling 7th graders who need a confidence-building recap, and for advanced 4th graders ready to stretch. Because each page is one topic, you can hand out the pages that match what you are teaching and save the rest.
