Aba-Conundrums give logic and reasoning room to move as children slide into real mathematical success! These 120 puzzles will have children shuffling their abacus beads up and down as they solve clever conundrums using their knowledge of numbers and a variety of mathematical skills. Aba-Conundrums includes a brightly colored abacus and spiral-bound puzzle book with a marker and erasable pages. Put the electronics away and explore the world of numbers with this ancient, multi-cultural calculating device!

Author's note: When my friend Bob Sweat brought me back an abacus from his trip to Asia and suggested that I might want to create some puzzles for it, I didn't even know how to use an abacus. But I took his suggestion as a challenge and ended up having great fun creating this set of puzzles. Finding a publisher was also challenging, but that's another story. I just want to say, "THANK YOU, Bob!"


Dedication:

“This book is dedicated to all my wonderful Asian friends and to an omniscient God who needs no counting device to know even the number of hairs on our heads.”
