Shape Sorting Box: Although this sorting box is recommended for 2-4 year olds, it is perfect for young toddlers (18 months to 2 years). Although toddlers grasp the concept of object permanence, they still love pushing back the wooden lid to find the blocks inside. If you slowly show toddlers how to place the blocks into their respective cutout shapes, they will master it in no time. I recommend showing children how to use this material and then allowing them to explore with it on their own.
