Montessori Human Organ Match - Miniature Body Parts with Cards to Match - Early Childhood Biology Learning Toy This Montessori learning activity focuses on matching miniature human organ figurines to their matching realistic photo cards. Children lay out the cards and place the miniatures on the matching picture. This set is also a perfect addition to science lessons. Visual Discrimination: This activity focuses on more advanced preschool matching. The objects are not an exact copy of the photo so children need to carefully observe details to match correctly. Includes 10 miniature organ replicas (.5"- 3" Long) - 10 laminated cards professionally printed on 100# cardstock and laminated with 5 mil lamination. The cards are classroom tough. Cards are 2.6"x 2.5" Noticing subtle attributes, such as color or shape, is a building block to reading and math. For example, when your child notices the similarities and differences in shapes, such as a square and a rectangle, they using the same skills needed to recognize the differences between letters, number and symbols. This is a handmade item. I created the picture cards and have them printed locally by a professional family-owned print shop here in Michigan. Item is simply packaged in a vinyl zipper bag. Please see photos.
