How much is signed first by starting with both your closed hands, four fingers touching the thumb on either side of your body, facing up. Then move your hands upward, with palms still facing up and fingers opening wide, and make a questioning face.
This is a great sign for older children to use when playing show. Children can make a game out of using how much, along with the name of an item, such as an apple. Then another child responds with a number.
Use the how much quantifier to equip our babies with more control over the things they want and the things they may not want. We use it for food portions or during play. For example; we can ask your baby how much candy he or she wants.
