From High and Low to Fast and Slow, opposites are full of fun in this Sandra Boynton board book favorite.Boynton's delightful rhyming text and whimsical cast of animal characters, who play on a teeter totter, lift weights, talk on the phone, and hide under umbrellas, perfectly complement the concept of opposites while introducing little readers to new words and juxtaposing ideas. Hot and cold Young and old Wet and dry Hello! Goodbye.
