Telephone Keypad Puzzle
Ready for a rough, tough code-cracking activity? In this excerpt from our Spy Math workbook, your kid gets to help secret agent Ian Danger by cracking the code on this mysterious fax sent over by his archnemesis, Walt Warner. Your kid can "call" upon (sorry, we couldn't help it!) his own logic and deduction skills to narrow down the letters contained in this scrambled note!
