Preparation

- No Prep required! Print the student pages, staple or place in a folder, and your students are set to go.

- Have the video hook ready for viewing at the start of the lesson on an IWB, iPad or computer monitor screen.

- Editable hideouts list included: This enables you to change the location names and alter the mystery outcome. Two alternative pre-made lists also included for a quick swap out.

-----------------------------------------------------------------------------------------------

Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

Clue 1: Subtracting Decimals (Wholes/Tenths)

Clue 2: Subtracting Decimals (Wholes/Tenths/Hundredths)

Clue 3: Subtraction Word Problems (3-digit to 6-digit whole numbers)

Clue 4: Subtracting Fractions (Like Denominators, simplifying required)

Clue 5: Subtracting Fractions (Unlike Denominators,simplifying required)

Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities.

----------------------------------------------------------------------------------------------

Multiple Uses

- Suitable for independent, pairs, or group work.

I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, then move on to the next clue either within the same lesson or the next math session. New math content presented? Make a lesson out of it by modeling the math before diving into the clue. I like to say, "we must learn something new before attempting the next clue."

-----------------------------------------------------------------------------------------------

How long will this activity take?

Time to complete will vary anywhere between 30mins - 2 hours or more! It mainly depends on how familiar your students are with the math mystery format, as well as how difficult they find math skills covered in the particular mystery. Please check the math skills outlined in the clues above to help determine suitability for your class.

Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, π’/π£ + π€/π₯ = (π’π₯ + π£π€)/π£π₯.)
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
