The user is invited to engage in 5 different puzzle types- Word Find, Missing Vowels, Scrambled Words, Nurikabe & Mine Finder- in this 6 X 9 activity book, featuring the bridges of North America. A great gift idea for ages 12 to 18+ that invites the user to use a computer to dig deeper and discover bridge types- especially arch, truss, suspension and beam- and to see real life pictures with facts about construction, purpose and historic value of these bridges. The Mine Finder and Nurikabe puzzles encourage thoughtful logic skills.
