sensory balloon with matching cards. great for teaching 5 senses to preschoolers or keeping toddler hands busy! Except make balloons all one color, or else they'd memorize the color rather than rely on senses to determine contents.
Teach with Trash: Tissue Box Science It would be a good idea to use these as mystery boxes. Place six items in boxes and have them guess what the objects are or what they may all have in common. Could be used to introduce a new unit or book.
