Children classify card images into categories. Cues from the matrix card's horizontal and vertical axes show a pattern. Children distinguish the logical progression of images with classifications such as, “nearest, near, far and further; lowest, low, high and highest”. A variety of descriptions may apply to each, so the children can extend their vocabulary with team work. Contents: 6 plastic matrix cards 96 plastic image cards manual wooden box (34 x 34 x 7 cm)
