Scientific notation worksheets, converting standard form numbers practice pages, and self-checking Mini Mystery Detective pack of math activities for 7th grade, 8th grade and 9th grade are all included in this printable detective pack. Students write very large and very small numbers in scientific notation - moving the decimal point, counting the places, and deciding whether the power of ten is positive or negative. Perfect for math centers and stations, guided math and small groups, warm ups and bell ringers, homework and independent practice, spiral review, test prep, intervention, tutoring, enrichment, early finishers, substitute plans and homeschool. Completely no prep - just print and go.
Every case is set in space: a missing moon rock, a radio dish that has gone silent, a stolen star chart, a torn spacesuit, a frozen countdown at mission control. Miscount the decimal places and no suspect matches - the pages check themselves, so students go back and find their own mistake before it ever reaches your marking pile.
What's Inside
- Writing large whole numbers in scientific notation: 630,000 = 6.3 x 10^5
- Working with numbers into the millions and hundreds of millions: 245,000,000 = 2.45 x 10^8
- Writing decimals smaller than one with negative exponents: 0.00074 = 7.4 x 10^-4
- Counting decimal-point moves rather than digits, so the exponent is never one out
- Keeping the coefficient between 1 and 10 and dropping the zeros the point moved past
- Mixed pages of large and small numbers, where the sign of the exponent has to be decided every time
- A one-page reference sheet on how to write a number in scientific notation, with the decimal point hops drawn out
Five leveled cases run through one space mission: The Missing Moon Rock, The Silent Radio Dish, The Stolen Star Chart, The Torn Spacesuit and The Frozen Countdown.
Answer keys, a detective's case log and a certificate of achievement are included.
What is a Mini Mystery Detective?
A no-prep detective activity where students solve math problems to cross off suspects and unmask the culprit. Skill practice plus critical thinking in one engaging, self-checking worksheet set - like an escape room without the locks.
