This simple, classic toy starts with a hard plastic frame and a set of colorful cotton looms that kids can weave to create real potholders. Teachers, especially for first and second graders, consider looms a valuable learning toy. In weaving loops, six-year-olds get invaluable practice with pattern and sequence, thinking skills they're learning in early math. They also improve small motor skills, which they need in order to master writing. (Hearthsong, $9.98)
