Secret Number Puzzles

These are super fun and highly addicting! Students are given a set of clues and they have to work through them to come up with the Secret Number!! Note: Levels roughly correspond to grade levels (with Level 0 being Kindergarten) but it's really up to you and the class dynamics which level you give your students. We sometimes use them to review concepts we've taught, other times to preview upcoming math concepts to a very captive audience :) Enjoy!
