Wilbooks: Books from Bruce

Bruce Larkin, the published author of over five-hundred early children's books, including the extremely popular Larkin's Little Readers Series, would like to promote literacy through book ownership.

Larkin has generously agreed to donate sets of fifty (50) free books at the pre-kindergarten, kindergarten, first grade, and second grade reading levels. Through the Books From Bruce program, children can be given books to call their own. Book ownership and books in the home are good indicators of future success in school. Bruce Larkin believes all children and their siblings should enjoy the advantage of having books in their homes.

Math titles include:

  • Patterns All Around Us
  • Animals with Stripes
  • A Dollar Bill
  • Puppies Run Away

Brainfreeze Puzzles

Philip Riley and Laura Taalman create colorful, hand-designed Sudoku variation puzzles with additional rules that challenge you to rethink your old Sudoku strategies and encourage you to devise new ones. This website accompanies their book, Color Sudoku, with free example puzzles and solving tips.

Stan Wagon developed the semester's first Macalester College Problem of the Week based on Riley and Taalman's Sudoku variation, as announced on the mailing list that the Forum hosts for him:
