Wollygoggles and Other Creatures Author:Thomas C. O'Brien Teachers, this is one of THE best sources for your young thinkers. Wollygoggles is a collection of reproducible brainteasers, all clustered around mathematics and nonverbal skills. I use them with my gifted students, grades 3-5, and they beg for more!

See if you can tell what makes them a Wollygoggle! WOLLYGOGGLES: 1, 4, 9, 36 & 121 . "NOT" Wollygoggles: 5, 12, 33 and 130.
