6th Grade Review | Math Mystery Worksheets | Back to School | Ratios Percent Area

A whole year of 6th grade math, one topic per detective case — students solve each problem, write the answer in the box beside it, match it to a suspect, and cross suspects off until one is left standing. This no-prep, printable, self-checking Math Mystery is built for the first weeks back, and works just as well for spiral review, math centers, bell work, homework, early finishers, substitute/relief days and test prep. Every page is a different standard, so the pack doubles as a beginning-of-year diagnostic.

The 10 Mysteries

The Mixed-Up Recipe — Every recipe table has one number rubbed off, and each table follows a single rule across.

The Split Rations — The camp cook lost the tally sheet; every question asks how many times the second amount fits into the first.

The Discount Dodge — Every fair price was marked down overnight, and each tag asks for the amount off or the full price.

The Coded Lockers — Every locker code was rewritten as an expression, so the order of operations opens the doors.

The Freezer File — Someone moved every marker on the temperature line, and students read two points and evaluate.

The Balanced Books — The clerk weighed every delivery instead of counting it; each scale balances, so students solve for x.

The Muddled Scores — The summary sheet blew away, and each set needs the measure named above it.

The Crooked Signs — Every sign was cut to the wrong shape; students find each area, with the dashed line as the height.

The Practice Log — The register went missing, leaving only the plot of how long each cadet practised.

The Flat-Pack Fraud — A pallet of unfolded, unlabelled boxes arrived; each net folds into one box, so students find the surface area.

Why Teachers Love It

Zero prep — print and teach. The built-in answer keys make every case self-checking, so students get instant feedback and stay motivated. Because each page targets a different standard, the pack tells you in one sitting which topics your incoming class actually holds — and the detective hook pulls in reluctant and struggling learners who would stall on a plain review packet.

Skills Covered

Ratio tables and equivalent ratios, dividing fractions, percent of a number and discounts, evaluating expressions with the order of operations, integers on a number line, one-step equations, mean, median, mode and range, area of triangles and parallelograms, dot plots, and surface area from a net — plus logical reasoning and deductive elimination as students rule suspects out clue by clue.

What's Included

Printable one-page mystery worksheets, one math topic on each, suspect line-ups, complete answer keys with the villain marked, and student instructions — all in one PDF.

Best Used For

Back to school review, beginning-of-year diagnostics, spiral review, math centers, bell work, homework, early finishers, substitute/relief days, and test prep for grades 6–7.
