The Box is Locked! Multiplication/Division Challenge Holiday Sweaters, Christmas

The Box is Locked! is an engaging math challenge for the Christmas holidays, with a multiplication and division story problem focus. Franny has built quite the online business selling her Granny's ugly holiday sweaters. She's looking for some qualified business partners, so she came up with this challenge for your students! Franny has locked a prize inside of a box, and students must solve her clues and find the key to open the box! (*Note: no mention of a specific holiday, like Christmas, is given within the resource.)

Students must DO MATH and BREAK CODES in order to solve Franny's six clues! Clues involve engaging number stories (all multiplication/division based) in which the answers are needed to complete other clues; construction of "Franny's Decoder Tube" (don't worry, it's actually pretty simple to make) to figure out a password; and even a "Shift Cipher" secret message that reveals the location of the hidden key. Once students find the key, they’ll open the lock and share Franny’s prize with the entire class!

I provide you with:

• an opening note from Franny to set the scene
• ideas for prizes including a collectible ribbon/bookmark (collect them all!) and a sheet of homework passes
• paper lock, key, and straps to secure the box containing the prize. (You could also use a real lock and key with a box secured with a chain.)
• SEVEN difficulty levels of clues with multiplication/division story problems and clever puzzles that students must solve in order to ultimately find the location of the hidden key. ("Difficulty Levels At-a-Glance" Chart is included to help determine appropriate level.) See below for further details on levels.
• Full answer keys
• Step-by-step, detailed instructions on how to set up the materials, including: preparing the prize box, hiding the key (two specific options provided), setting up the clues, and leading the activity.

All you provide is a box that closes, like a shoe box or storage bin. (For this "The Box is Locked" activity, students will also need scissors and a little bit of tape to complete certain clues.)
