BRAIN TWISTERS. Hayes, Paul. Illustrations by Peggy McEwen. Shane Doyle, Rick Rowden, Jodi Shuster. Sami Suomalainen, Ashley Lenz and Arnie Lipsey. Burlington, Hayes Publishing, 1987. 32pp. paper. $3.95, ISBN 0-88625-149-4. (Mind Benders series). Grades 4 to 7 Reviewed by Maureen Pammett Volume 16 Number 4 1988 July The third in the "Mind Benders" series, this volume follows much the same format as the others in the series. Forty-three brain twisters are included. As might be expected, there is more reading involved in grasping the problem. The same variety is evident here, and the solutions certainly require creative thinking. Once again, excellent fare for the children. Another title listed in the series is Number Mysteries.* Maureen Pammett, Bridgenorth, Ont. *Reviewed vol. XVI/3 May 1988 p. 101.
