Colourful and beautifully illustrated, these durable two-piece Opposites Puzzles help build student confidence with phonics, word recognition, and vocabulary development. Students read the word and then find the matching puzzle piece with the word's opposite, such as long-short, cold-hot, sitting-standing, etc.. The set includes 30 self-correcting puzzles and a teacher's guide with suggested activities and extension ideas. Each completed puzzle card measures about 11.5 cm x 9.5 cm (4.5" x 3.75").
