Principal Shaw is retiring. In his honour, the people from the neighbourhood gather for a carnival and picnic in the schoolyard. One of the booths is a dunk tank and Eddie, a student, sits in the hot seat. Blindfolded, his challenge is to guess the age of each contestant in three tries or less. Using his ability to compare numbers, Eddie remains dry for a long time. But when Mr. Shaw's turn comes, Eddie goes for a dunk. At the end of the book, suggestions for additional activities help adults and children explore number comparison further.--Ministry of Education website.
