Colorku: Color version of Sudoku complete with wooden board, 81 wooden marbles, puzzle cards, cardholder, solution sheet and plastic lid. This is waaaay more suited to my yellow/red quadrant / right-brained self!
Perfect for long car trips and airplane trips, this small wooden mosaic puzzle will keep them happily busy creating all sorts of colourful patterns. Made of bamboo, the Geo Form Puzzles are also a good choice for an eco-friendly gift.
DIY Portable LEGO Kit with Free Printable Activity Cards. I like this for school, older kids can have activity cards to create planets/atoms/molecules/fractions, younger ones can practice fine motor skills.
