Perfect for five- and six-year-olds, this appealing collection is full of fun, with riddles to solve, grids to fill in, and word games to play. In “Book Reviews,” children have to match up author names with book titles: they’re punning pairs, with BILL E. GOAT as the writer of LIFE ON A FARM, for example. “A Symbol Puzzle” provides a simple introduction to cryptology. And can young solvers find the state names (Alaska, Indiana, Ohio) hidden in some silly sentences? What a great way to build language skills!
