This reasoning activity challenges students to use the clues provided to figure out which number the butterfly was hidden behind. Students read each clue and eliminate the numbers from 1- 50 that don't fit, crossing them off on the number grid. They continue clue by clue until only one number remains. Included is the PDF document (downloadable), which includes 6 logic problems, answer key and a blank template for students to create their own Hidden Butterfly logic problems to challenge their classmates.
